#picoice — Public Fediverse posts

Not having #AMD #Xilinx #Vivado #Chipscope based live #hardware debug for the #picoice #Lattice #ice40 #FPGA was a little annoying

so I am hoping to revive the small pipelinec project that was sorta a build your own chipscope attempt 🤙 and demo that on the pico ice

^^^ Is an excellent video describing how the FemtoRV works. I will soon be comparing #Mecrisp #ice with Risc-V, so the timing is almost perfect.

Here are the instructions for using #e4thcom with #mecrisp on the #picoIce. #Ice40 #fpga #forth

I am interested in building a #uxn cpu on an #fpga.
I have already built #Mecrisp #Forth on the #PicoIce.
A Uxn cpu is just a slightly different stack machine.
Maybe I will eventually build an entire Varvara computer on an FPGA.

I now have a Mecrisp Forth core running on the pico-ice FPGA.

Here is the documentation for the #PicoIce echo server.
It lets you test connecting #micropython #forth or other languages running on the #RP2040 to the #ice40.

I received an #upduino and a #picoice circuit board this week, got the basic tools working, and am working on an echo server. Soon I will be building a #Mecrisp #Forth core.

I am giving a talk on #Forth this week at the #fpgaworld conference in stockholm.

#ZeptoForth boots on the #PicoIce, which means that the default power, usb and flash pins are correctly connected. Which means that #MicroPython and #Mecrisp probably boot as well.

As soon as I get my #FPGA working on the #Upduino, I want to buy a Pico-Ice, and check out the REPLs..

I am building a many core #Forth processor on Lattice Semiconductor FPGAs using the open source #Yosys tools. The first products released will be two 4 core processors. 16K* 16 bit words or 10.6K * 24 bit words. Every pair of processors will communicate using 10Kbits of dual port RAM. The processors will run on the $35 #PicoIce and $30 #Upduino boards. Later there will be hundreds of cores on the larger #ULX3S #ECP5 boards.

This is the board I am planning on using. Just be careful not to short circuit the board.
