What are your cogs doing ?

Cluso99

Taking a break, so thought I would let you know what my cogs are doing...

Cog 0 : Launches the RamInterpreter, then launches other cogs, then compares their output and speed
Cog 1 : Runs FullDuplexSerial
Cog 2 : Runs ClusoDebugger (currently pasm but being modified to include spin)
Cog 3 : -free-
Cog 4 : -free-
Cog 5 : Runs the RomInterpreter and a Spin Test routine
Cog 6 : Runs the RamInterpreter and a Spin Test routine (known working version)
Cog 7 : Runs the ClusoInterpreter and a Spin Test routine (this is being debugged)

I am glad I don't want to run VGA

I can't resist this one:

Cog 0 : Runs a supervisory task
Cog 1 : Runs a variant of FullDuplexSerial
Cog 2 : Runs an SPI driver for the ENC28J60 ethenet chip
Cog 3 : Runs an SPI driver for an SD Card
Cog 4 : Scans 24 analog channels at a rate of 1000Hz per channel
Cog 5 : Scans 8 digital channels for signals at up to 15kHz per channel
Cog 6 : Process the changes detected by cog 5.
Cog 7 : Free, totally free.

And I've still got 817 longs of memory left!

This is before the application of JDForth - I'll post a comparison once the code has been converted (About 50% done).

JDForth - Forth to Spin Compiler http://www.jacobsdesign.com.au/software/jdforth/jdforth.php
Includes: FAT16 support for SD cards. Bit-bash Serial at 2M baud. 32-bit floating point maths.·Fib(28) in 0.86 seconds. ~3x faster than spin, ~40% larger than spin.

I have two props that talk to each other on the same board so:

Prop1:

c0: spin, not used after launch
c1: 320x240 mono LCD refresh (~60 Hz)
c2: 4 Bit bidi comm to other prop
c3: bitmap refresh
c4: oscillator and keyboard scan
c5: game of life
c6: not used
c7: not used

prop2:

c0: spin, not used after lauch
c1: ADC, 500 kSps
c2: FFT 1024 points
c3: comm to other prop
c4-c7: not used



But most of my projects are just small pieces of assembler code, so I use the simulator.

I should get one :> ... now that I can.

I have 5 proto boards in diferent configurations and diferent COG use.

And reprogram it very often in my experiments.

Nothing is impossible, there are only different degrees of difficulty.

For my main experiment controller which runs about 4 different pieces of equipment:

C1: Menu system, data entry, program flow, TV_Text
C2: TV
C3: Keyboard
C4: Motion control
C5 -C8 Empty so far, plans for a strobe sync

Hey, one could do pictures of ...· ;-)

(now what order did they startup in?)

Time to ask again - what are your cogs doing??

Sometimes I'd really like to know !

Current effort is:

8080 CPU part 1
8080 CPU part 2
8080 CPU part 3
8080 CPU part 4
Keyboard
TV
SD Card
Free

Yep I'm trying to speed up the 8080 emulation by using 4 COGs. Very early stages yet.

For me, the past is not over yet.

0. Main Cog (Eeprom R/W, Commands in/out from USB, Blinks 1/3 LEDs, Checks Errors, 16Bit D/A converter)
1. FullDuplex
2. Loops a 16 bit A/D taking 1000+ samples / sec
3. Math crunching A/D and floating point numbers
4. PWM a Motor

Guessing: about 4000 Lines of code in cog"0" alone and 1/2 memory used total all cogs.
