I presume you have 2-3 latches for the address lines or are you using a CPLD?
I think there is a nice translucent blue version sparkfun case that would be nice.
XMM
===
There is no doubt that the differing versions of XMM will be slower than hub ram access, but it opens up access to large programs that may not necessarily require the full speed of the prop, but do require its intelligent peripherals by using other cogs. There is no doubt that all these XMM versions will make an impact on the applications of the prop.

I saw your post [noparse]:)[/noparse] Don't be shy. I was just thinking the next new board I do will be a latched 32 bit wide data bus straight from Propeller and clock-latched address with memory mapped perpherials and a second Propeller just for fun [noparse]:)[/noparse] First level device access using upper bits in the address phase from Propeller for command signalling will be monitored and acted upon by a small CPLD (or the secondary Propeller) and latches. A second level Bridge device will allow connections to other peripherals via a large address and data bus (think in terms of 100's of MB of SDRAM) and whatever can be connected to remaining pins on the secondary Propeller. ... Now where's that thread you started where I suggested a 20MB/s XMM bus is possible?
@Bill and @Ross, thanks guys. Now back to·my XMM C demo.

Looks nice in a box. Yeah $10-$12 is a bit steep, but you don't have to put it in a box, but it sure is nice to be able to do so.

if I would like to use it with SD-card, VGA, mouse, and keyboard there are no pins left for other things
except maybe P28-29 with I2C-IO-expanders
So I'm asking what kind of applications can be done with no IO-pins left for sensors or actuators ?

Wading through the Xilinx tutorial, it struck me that a parallel load, up down counter can easily be implimented on CPLD.
Take for example the code below. Can write a 16 bit address for random access and inc or dec the counter for sequencial access by clocking a single Pin X times.
What are your thoughts ?

It is possible to share I/O pins across multiple devices.
As an example, I reasoned I could add an sdcard to a board
that has no free pins, but that has an LCD shared with I2C bus.
regards peter
@Ron, The function sounds a lot like the HX512K CPLD. Instead of having to spend Propeller instructions sending a clock, it seems to me that anyone could load a down counter and use a free running clock. I assume you've also looked at the CPLD discussion in the 6.6MB/s thread. That looks like VHDL which I never bothered to learn but except for some of the horse designed by committe stuff, I can get the functions ... looks a lot like Verilog in many ways. I always thought Spin was influenced by Verilog/VHDL.
@StefanL38, there are 4 pins free if TV is used instead of VGA. I was thinking about a hand-held game console using QVGA or TV, a tiny joystick instead of mouse and some action buttons or accelerometer instead of keyboard. The DIN-6 connectors very conveniently have +5V like all mouse/keyboards, but I've never heard of anyone on this forum using a DIN-6 for connecting a GPS or other devices. Something to consider.

-OE Sorry I didn't know what you were doing to warn you. I fell into that trap with my TriBlade
Yes, I am using the Hirose microSD from DigiKey HR1941CT-ND. It is fairly easy to hand solder as the pins are exposed. Don't forget to not place any tracks under parts of the socket as it could short
I also found the CUI smt audio jack 4 conductors (for TV and audio using iPod video standard pinout so you can buy RCA cables cheap from eBay) DigiKey CP-43514SJCT-ND, VGA DigiKey 609-2802-ND, PS2 DigiKey CP-4060-ND, miniUSB DigiKey WM17115-ND, RCA (TV) DigiKey CP-1403-ND, Power Sw DigiKey 679-1854-ND, Pwr Connector 2.1mm DigiKey CP-202A-ND (we use 2.5mm in Australia). Some of these are smt and some are t/hole. Hope this helps
Would be great for everyone to use the same parts where possible

The counter is basically loads just like the 16bit latch, but it can also be incremented and decremented from an additional CLK pulse To provide faster addressing of a block.
Yes you are right HX512K without the 8bit bottle neck. Umm ...Maybe I should set up a post increment mode......more to think about
I do like the little prop in a box, really neat. There will be lots of interest in it I'm sure.
Ron
Funny you are using the same audio jack as me; I figured I could mount the smaller circumferance device in the same pads if necessary for iPhone head-seats. The one on the board has an extra pin on the back and there must be 10K of those at ACE around the block.
I too was attracted to the exposed Hirose uSD pins, and from the looks of of the loops on this prototype board (could not find a ready made eagle body), that was a good decision [noparse]:)[/noparse]
@Ron, glad you like "prop in a box" [noparse]:)[/noparse] An enclosure is almost always the hardest thing to find (at a reasonable price) except for cell-phones (search "housing" on ebay for examples ... lots of cool stuff there in Hong Kong). Post-increment is not very useful to me since you have to strobe something to make it work. I would rather just say "give me N bytes on t schedule" and then suck up the bytes with a wrbyte loop (or other collection mechanism like a long string of self-modified words).

Which flavour of Xilinx chip were you aiming at ?
I am just about to start experimenting with some XC9532s, which I had lying about. I have made the PIII cable interface, an elaborated XC board, a bit like Leon's, and a few input switches and output LEDs. XC9572s would fit as well but 144s and up, would req another board.
Also which is better VDHL, or Verilog (for a beginner). Most of the written stuff I have here is Verilog. I was originally aiming to bolt them onto Z80s, but the prop would not escape.

Well I have only just started playing with Xilinx Coolrunner, so I am no expert. I have been working through the VHDL Tutorials. I am thinking in terms of XCR3064XL.
There is plenty of resources to do the job, but I am thinking that Dram is so inexpensive the cost of a $10 CLPD is not so important. The more I play with this Coolrunner the more I like it.

Yes, but the clock should generated by a Propeller pin so it can be a good multiple of crystal frequency and gated, etc... if necessary.

Well, in any event the only way to get great data rates with low interface pin counts will be with a CPLD (serial data rates are nice but not great). But even with a CPLD there is number crunching to do before actual transactions happen.
Meanwhile, If no one is interested in the product based on the list above, then this is a dead duck. I'll finish the XMM C demo to see if it's worth anything, but I'm out of time for now [noparse]:)[/noparse]

Anyway, you cold probably drive a 41lV16100B Dram with 21 pins directly from the Prop, without external latches. We are all paddling own own
canoe at the moment [noparse]:)[/noparse]
@Kuroneko any thoughts on using Dram and CPLD to emulate Sram, could be cost effective

Wait till the smoke clears from UPEW. There's so much stuff going on at the moment that it's really hard to figure out where it's all going - but good designs will always sell.
The C demo would be a good selling point (not trying to self-promote here, since I presume you mean using your XMM extensions to ICCPROP). It just seems to me that most of the XMM boards currently under development are either being used to support various processor emulators, or to support C programming. Or did you have another application area in mind for your board?

It is obvious, there is a lot of interest with 2·items...
It is easy to tell this from the number of posts and views.
There are·3 or 4·very specific applications for External memory...
As long as it does not break your bank, every effort is worthwhile. I have no doubts my solution is correct for emulation and PropOS because random access to bytes is paramount and so is speed, particularly in emulation. However, other solutions such as yours are likely to be·better for sequential long access. There of course will be refinements. The RamBlade circuit (be it over 1 or 2 pcbs is irrelevant) is second generation and is manifestly simple, cheap and fast for what it is intended to do. It is just how to "package" the circuit which has to be refined for maximum benefit to others.
FWIW There are about 25 TriBlade pcbs out there.· It didn't cost me too many $$ other that time, and I really enjoyed designing and discussing it.
When I get some time (after RamBlade, etc) I think I may·resurect my faster Spin Interpreter to use XMM.

My main goal with XMM is to execute LMM C programs using as few Propeller pins as possible.
Someone pointed out that having only 20 free Propeller pins is still not enough though [noparse]:)[/noparse] oh well.
I'm considering a multi-propeller variant solution as I previously articulated in a response to Ron.
Haven't drilled into the gory details yet, but the idea keeps bubbling back up.
The idea of the same number of transactions for any data type width is a goal.
Interface transactions might be doable with 5 instructions for read.
The idea of a 256MB or 512MB linear address space is also very attractive [noparse]:)[/noparse]
@RossH, BTW I am very serious about providing drivers for use with Catalina.
I'm just challenged by time and the amount of work to do right now.
At least the board I'm developing has a 128KB EEPROM for EMM/XMM and uSD adapter [noparse]:)[/noparse]
