New 16-Cog, 512KB: Instruction List plus Semantics & Naming discussion

Here is the latest instruction set posted by Chip ~9 Apr 2014
I will try and keep this updated until the next FPGA code release.

I have proposed a few changes in the posts below that may simplify things, make the manual easier to write, and reduce the perceived number of instructions.

    Note I fixed the missing "D/#,"

    This only changes the compiler, which now must recognize #LO, #HI, #XOR, #OFF, #Z, #NZ, #C, #NC as reserved names, but simplifies it down to one instruction.

    This reduces the instruction count (theoretically) and simplifies the manual.

    The only change to the existing instruction coding is I have rearranged the lower 3 bits of "S" (mainly to permit #0 and #1 for CLR and SET).

    Thoughts anyone???

    Replies were as follows:

    Does GETP become GETPIN and GETNP become GETNPIN so it's consistent?
    Yes, I think there are quite a few simple changes that could be made to simplify things.

    Did you mean one assembler mnemonic, rather than one instruction.
    There are still 8 unique opcodes/instructions.

    A single form has merit, but if you want to use a param to indicate the action then SETPIN is better as MOVPIN, or WRPIN
    SETP was already use to SET the pin - most programmers expect SET to do what it says

    MOVPIN/WRPIN semantics work on all cases, except for the XOR case, where #XOR is a little confusing.

    To keep a common name of WRPIN & using your form, then this would do what it says.

    WRPIN #NOTPIN

    and pairs with
    RDPIN
    Yes, one mnemonic. Yes MOVPIN or WRPIN/RDPIN might be better, and #NOT or #NOTPIN.

    While I am at it, I think SETS / SETD / SETCOND / SETINST were nicer as MOVS / MOVD / MOVCOND / MOVI or MOVINST.
    Thoughts?

    Following on from...

    OFFP/NOTP/CLRP/SETP/SETPC/SETPNC/SETPZ/SETPNZ

    replaced with the single instruction...

    WRPIN D/#, #0 / #1 / #NOT / #OFF / #Z / #C / #NZ / NC

    and...

    GETP/GETNP

    replaced with...

    RDPIN [#NOT], D/# WZ,WC

    thoughts??


    Does this make sense...

    ISOB/NOTB/CLRB/SETB/SETBC/SETBNC/SETBZ/SETBNZ

    replaced with the single instruction...

    WRBITS #0/#LO/#1/#HI/#NOT/#ISO/#Z/#C/#NZ/#NC, D,S/#

    (maybe change the operand positions???)

    #ISO might be (not quite sure what it does)

    RDBITS #ISO, D, S/#

    Similarly...

    SETPTRA, SETPTRB, SETINDA, SETINDB, SETINDS, GETPTRA, GETPTRB, ADJINDA, ADJINDB, ADJINDS

    might be better as...

    SET #PTRA/#PTRB/#INDA/#INDB/#INDS, D/# [,S/#]
    GET #PTRA/#PTRB, D
    ADJ #INDA/#INDB/#INDS, D/# [,S/#]

    To be honest, I find the SETP, CLRP, etc... easier to remember. The absolute number of instructions isn't a big deal to me. Mnemonics that resonate with a simple verbal representation of the function are more valuable.

    One general SETPIN with odd modes is non-optimal, particularly given the reserved names. Much prefer the simpler case for readability, ease of discovery, etc...

    I also prefer the simple D & S argument form. That's an awful nice attribute of PASM. Going to 2 and sometimes 3 and maybe one is something I would prefer minimized.

    Focusing on the number of primary instruction mnemonics at the expense of more arguments and or fiddly keyword space doesn't add value, IMHO.

    I think the semantics are critically important at every stage. The actual names are not… what seems like a perfect name for an instruction to one person might just as easily create confusion in the next for reasons that really cannot be controlled or anticipated. Clear semantic representation and a good cheat sheet are probably all that can really be achieved by mashing the subject.
    I would like to see any suggestions for simple name changes wait until the work is mostly done. At this point, it is really best that Chip use names that make the most sense to him.
    So, I am happy that this is about semantics and not about names!:)

    Heater has correctly identified the area of stack memory and utilization to be one of those areas that troubles new(and old) users and could use a good semantic overhaul. When I first encounter the area, I was surprised that "stack" was not a reserved word with special meaning to the compiler. The user shouldn't be forced to use this keyword, but it should be a keyword with special meaning.

    Cluso,

    Do you need these pin instructions? I know they are convenient, but if they didn't exist, would you really suffer? I realize that this is not an issue of semantics, but this is your thread so I know you won't miss my question… and I don't want to start a new thread just to ask you a question. Would it slow down execution?

    Cluso,

    Do you need these pin instructions? I know they are convenient, but if they didn't exist, would you really suffer? I realize that this is not an issue of semantics, but this is your thread so I know you won't miss my question… and I don't want to start a new thread just to ask you a question. Would it slow down execution?

    Rich
    Chip put them in, so I presume they don't take much.
    However, they do make life easier to write directly to a pin (each of the 64 pins can be addressed, but only 1 at a time), so it does make some drivers much simpler to code, and perhaps faster to execute.

    Looks good Cluso. Filed for cheat sheet later on.

    You know, once we get the FPGA, it might be worthwhile to knock out some little samples and truth tables. I had some notes on the other design that were getting there.

    To be honest, I find the SETP, CLRP, etc... easier to remember. The absolute number of instructions isn't a big deal to me. Mnemonics that resonate with a simple verbal representation of the function are more valuable.

    One general SETPIN with odd modes is non-optimal, particularly given the reserved names. Much prefer the simpler case for readability, ease of discovery, etc...

    I also prefer the simple D & S argument form. That's an awful nice attribute of PASM. Going to 2 and sometimes 3 and maybe one is something I would prefer minimized.

    Focusing on the number of primary instruction mnemonics at the expense of more arguments and or fiddly keyword space doesn't add value, IMHO.
    Then perhaps the names should be more in line with a family. It is so much easier to read the instruction manual if the instructions can be grouped by naming.

    So if the pin instructions were PINOFF, PINNOT, PINCLR/PINLO, PINSET/PINHI, PINC, PINNC, PINZ, PINNZ they could be under the heading PINxxx and be describe simply. They can then be counted as a single group of instructions - means a lot when you say you have 160+ instructions or 80 base instructions. We don't want it to look too complex (remember the comments about the 400+ instructions.

    And yes, its worthwhile discussing while Chip is doing other things. We can suggest, but of course he is the arbiter. Currently we don't have an fpga to really play with so we might as well discuss something useful.

    Interested by what you mean by truth tables? Do you mean when Z & C are set?
    I would like comments to go with some of those more obscure instructions if anyone has the time and knows what they do. (We don't need to bother Chip).

    Sort of.

    Truth tables isn't quite right, but for the logical operators. For other ones, there are key inputs and outputs, like the ones we would use for testing that would be nice to have.

    Remember how Moto did it's programmers manuals? Sometimes a code fragment made sense. Other times, the edge conditions and boundary conditions were listed along with unambigious arguments. That kind of thing.

    The groups you have make sense. Rather than pack the header info into the instruction, which reduced clarity, simply add headers to the groups! Then the instructions can be as they mostly are, easy to remember.

    PIN, PIN, PIN, PIN...

    So we have group header

    Pins

    SETP, NOTP, CLRP, etc...

    Less overall to type, groups remembered once, etc...

    Of course a list of instructions looks complex! So does a simple number of instructions. In some basic sense, they are, but grouping things simply does a lot more damage on that problem than attempting to sort it all in the name of things, which generally fattens those up a lot, adds no more value than the group headings and other simple presentation devices do, and we type a lot more than we otherwise would in the end.

    Most of the instructions names are down to the nubs. There are some like the wait ones that aren't but they sure read well.

    So yeah, I really like the groups and would add headers and when we produce some reference material, can add some stuff there that I mentioned above. I don't mean to imply you should do it, or that it needs to be done now either. Wasn't my intent at all. I like your lists. And they are useful, and a great start for lots of other things!

    The fact that the R bit was repurposed into another instruction bit has confirmed my suspicion that, in the end, this chip and the original P2 will be nearly indistinguishable. It opens the door to 500+ instructions like there are on the P2. Now all we need is the CLUT and the fancy video hardware (and hubexec if it wasn't added yet) and the two chips will be completely indistinguishable. Please stop adding features and release something simple, like the P1, very soon, where the main difference is that there's just more preexisting stuff and no new features except encrypted bootloader, because that was one of the things high-volume people wanted, and really simple things like more pins (and dacs because they can be borrowed from the original P2) and hardware multiply.

    If this chip is too similar to the original P2, no one (i.e. high volume customers) will use the what was originally supposed to be P2 when it is finally released, and, even worse, the original P2 might never be released because there won't be enough incentive to release it. I probably missed something because there's been too much going on for me to keep up with, but wasn't this new chip supposed to just be something new that was a lot faster and had more cogs, pins, ram, etc. to increase the Propeller's usability and popularity so Parallax could get enough money to make what was supposed to be the P2?

    Does Parallax have names for these two chips yet? The original P2 is the P8X32C, right? What's the new 16 cog chip called? found it... P16X512x

    electrodude

    EDIT: And yes, there will be 500 instructions in this chip if things keep going the way they are now. Most of the instructions on the original P2 were added because they were necessary to complete recently added features or because they were easy. For example, taking away the R bit means you have to add TARG and friends, and adding hubexec means you have to add AUGx and screw up jmpret. Most of the instructions in the table above aren't on the P1 - they were taken directly from the P2. There are already 169 instructions, up from only 64 on the P1.

    Is it really worth it to rewrite the P2? If you're going to add almost everything in the original P2, why not just strip down the P2 instead of building everything back up on top of the P1?

    PINS are a good example where PINHI, PINLO, PINOFF, PINXOR or PINNOT (nice wine ;) ), PINC PINNC, PINZ, PINNZ, PINGET, PINGETN make more sense (at least to me) and can be grouped onto the same page in the manual, instead of requiring a page for each instruction.

    Reading a lot of comments this past week, I don't think the fancy video hardware is going to go in this 16-cog chip. It may have been a big part of what made it infeasible at 180 nm.

    I too am just resigned to taking what I can get from the P2 project.
    It's also a matter of perspective, is it fortifying and building up a P1? or is it stripping down a P2? Isn't it kind of the same thing at this point?
    P2 is obviously going to morph into something unique, with its own reason to exist.

    The awesome thing about the hardware description code at this point, is it can be moved around in large chunks. Entire features brought in or left out with a copy and paste and some glue statements. Size up or down some array elements. etc.

    It's not. In this process, that video hardware is too aggressive. What we do get is a waitvid that has more bits per transfer, and a fast, direct connection to the DACS. This is great! The old P1 waitvid can't move enough data to make both effective use of the additional RAM we've got, nor effective use of the DACS. From the description we have so far, it's been expanded enough to make some really great displays possible.

    VGA only, at this process, makes a lot of sense too. TV, Component and some other things we might want can be done in software. And they can be done well too.

    Some day, when we can get the other design in a process to match it, that video system is really great! And by the time it gets realized, the display tech will be well matched to it. Honestly, that video system is a great piece of engineering that needs to get out there someday.

    But this one will punch well above it's weight, and it will work more P1 style, which is just fine. We know how to do that too.

    What Chip is doing is a refactor, taking the good things he can, optimizing for power, and in a few cases, like the pins, thinking in new ways to realize some of the basic goals he has for the device.

    I doubt we will see that huge number of instructions. And we really should maximize what we can do in this process! It's to the benefit of everyone IMHO. Let him work a bit. Good things are gonna happen.

    Re: Pages

    Well, I see it a few ways. There is the programmers quick reference, and some programming model, block diagram, data sheet. For a lot of people, that's the primary tool.

    Having a page per instruction is killer otherwise! That's where a code sample, key cases, truth tables, logic diagrams, etc.. go. Some of those pages won't have much, but others will have a ton.

    Wrap that all into an online system, and anybody anywhere can type part of an instruction, get a code snippet, understand the cases they need to, and carry on just fine, quick and easy.

    Or, if they are older school, they can print it off and have a manual too. Personally, I'm beyond manuals when I can get resources like that. And as time goes on, those pages can be augmented with whatever comes up on the support side of things too. No need to republish, or anything like that either. Simply change the date stamp, and or post up a notification, and everybody goes to it when they need to / want to.

    What I still think is nice for manuals, books, is more cookbook, how to, philosophy, tutorial types of things. Moto had it right way back when, and that's precisely what they did. One page per, and some were filled, others simple, with wide margins so people could scribble all over the place. Map that to the tech we have today, and it's excellent, easy to maintain, and the work to populate it can be distributed among as many people as is necessary, up to one person per instruction!

    Imagine we all took 5 - 10 instructions and over the course of a month, produced those pages, simple. We would be done! And it would be excellent!

    Somebody else can package that down into the lean, mean reference docs, etc...

    Thanks Ray
    My question was that as their are no delayed instructions, the JPD and JPND are invalid now.
    Another query on LINK, In P2(is that called P3 now?) the return address was saved to COG address 0.
    Cheers

    Chip was still listing the JPD and JPND although maybe he forgot to remove them.
    The LINK has the notation that the return address is stored to cog $1EF.

    Do you know what the register layout is in $1Fx ?

    Just my 2 cents.

    When it comes to naming op codes I believe that it is better to have individual names for functions that a reader can spot and go "THAT looks like what I want".

    If you cram a bunch of modes into one op code (name) then it can make it very hard for someone new to find what they are looking for.

    Conversely, it is harder to find an opcode mnemonic when you don't know what its called. Much easier if they at least all begin similarly. Like WAITxxx groupings and BITS grouping and PIN grouping, etc.

    I have worked on so many micros, sometimes I draw a blank for a mnemonic and I have to look thru a list. Oh, and I might be having a "senior moment" ;)

    I have updated the first post with the Instruction set sorted into groupings, and I have added instruction operation comments and Z & C flag settings. They are those that I think I know - please let me know here if you find any errors or can fill in the blanks.

    So THAT is what I am having when I constantly have to go back and relocate that instruction that I know I just used the other day... LOL.

    Yes I agree common functions need common grouped naming formats so that it is easy to scan a list and see what is there.

    I drove my self CRAZY for weeks when I started with the P1 looking for the 'SETBIT' function command... Kept thinking I must be missing something somewhere and that was why I could not find it...

    Do the delayed JPD and JNPD need to be removed from the list?


    Because there is no pipeline in this new chip, there are no delayed branches. So, all those -D branches are gone.

    I put the PICKZC D/#,S/# instruction in, since it provides the most flexibility.

    Yes, I don't know what I was thinking. JPD and JNPD won't exist.

    I agree that it would probably be a good thing to name all the pin instructions "PINxxx".
