TYTEs - more than a word but not as long - agreed?

Dear Chip,

I use PNut to construct bytes, words, and longs, but what I would also like is an operator that takes 3 bytes. I'm sure it would be fairly simple to implement and the hardest part is coming up with a suitable name which is why I have suggested tryte for "triple byte". Now that I have done my part then how about it? Huh? :)

BTW, this is all your fault Chip, you made P2 handle unaligned data easily so seeing that I have 16-bit words addressing 64k which I could stretch to 256k I also thought well instead of a wasteful 32-bit address why not just use 24-bit addresses which are fetched with a long as the top 8-bits would be ignored in any memory reference. So if I can I will try trytes.

    That would be easy to implement in PNut. Remind me if it's not done soon.

    I was thinking that with the way the hub FIFO works, it could easily be made to handle any data size from 1 to 32 bits. The RAMs that we are using have bit-level write control, so it could work both ways. It's not practical to implement, at this point, but it could be used for things like 3-bit pixels, etc. I guess all addresses would need another 3 bits to get down from bytes to bits. Spin could be compiled into various bit-length data instead of just bytes. That's how the BASIC Stamp worked; that interpreter often just read one bit.

    Three nibbles makes a tribble? Sorry, it was too easy.

    trybble
  • Peter JakackiPeter Jakacki Posts: 10,193
    That's the trouble with trybbles is that they do more than nibble, they end up with a few bytes too many but at least they spot the Klingon agent. But i like the name, trytes or trybbles?

    How about dribbles/dreibbles from German drei for 3 :)
  • mindrobotsmindrobots Posts: 6,506
    Before long,
    tribbles will dribble,
    if bit two bytes
    past a nibble.


    Word!

    "trytes" is already defined as 6 "trits". A "trit" of course is the equivalent of a bit in ternary logic.

    so we are same generation ? ;-)

    a while ago there was Star Trek Night here and people selected the Trybbles episode as one to see again. ;-)

    average(WORD + LONG) = WONG

    That way, it's still 4 letters, like the others.

    Does that mean two WONGs don't make a WITE?

    Hi Chip, I think you're weally wong this time but you may be on to something. How about we shorten tryte to tryt to make it four characters and unique?
    I have amended the title accordingly.


  • evanhevanh Posts: 16,040
    Still clashes with the ternary Trit, albeit in pronunciation only.

    I suggest TWIT - Two Words In There, a lovely four letter acronym as well as a helpful mnemonic.

    TRIN?

    But WONG!

    Aren't two words in there, but since the hub is byte-aligned it does not matter. It's 3 bytes, so a TONG might work.

    But I do like the tribble or short TRIP. Yeah. That might work.

    Enjoy!

    TRIO?
  • Peter JakackiPeter Jakacki Posts: 10,193

    Let's see, we now have alternative suggestions for tryte as:
    • tribble
    • tryblle
    • dribble
    • driebble
    • wong
    • tryt
    • troglabyte
    • twit
    • trin

    Anything "ibble" based sounds good but a nibble is 4-bits so it would have to be hexiblle or "sexibble" but I favor a 4 letter version that at least sounds like 3 bytes.

    There most certainly are two words in there. This instruction is to take a long, ie 2 words on the Propeller, and place them into some new order of binary management. So with this in mind, I'm standing by TWIT!

  • msrobotsmsrobots Posts: 3,709
    I still think TRIP might be the best version. TWIT has some associations to guys like me and WONG seems to be - hmm - just WONG.

    All this dribble stuff, meh, but TRIN sounds good also.

    Enjoy!

    How about we don't try to name it. Instead, add

    RDBYTES D/#, S/#/ptr, #n
    WRBYTES D/#, S/#/ptr, #n

    xxBYTE, xxWORD, and xxLONG would just be aliases for N=1, 2, and 4 respectively.

    TYTE = tri-byte
    BYT3 = byte with backwards E

    I'm not quite following - Chip said this would be a PNUT ASM change, but your example suggests a packed reading of 3 bytes
    ( with presumably a matching Ptr+3 ). That's more than an Assembler change ?

    WONG is it! People around the great wall will just go crazy about it! :-D

    On the other hand the other permutation/contraption of LONG+WORD might even be better: LORD! Everybody knows christians have that sweet spot for trinity and everything-three! :clown:

    Would also sound like be me everytime someone suggests to extend the instruction word to some wacky number <> 32! :o

    I've just amended the tytle :) to gain consensus on this choice.

    Tytes or tights?
    http://www.oddee.com/item_98063.aspx

    tri-bytes seems to be a bit of better lexicon. Beware of men in tytes.

    Instead of 4 bits equaling a nibble, you could call 4 bits a tutu.
