@BrunoLevy01 yes!!! I’m currently rewatching the whole series so that I can read the follow up comic created by 4 French writers ☺️ #goldorak

@yrabbit @BrunoLevy01 I did not know, you are doing great! It seems as you are directly diving from the intro course into leisurely conquering a new arch, discovering sizecoding while at it :-) See you next time at the #Lovebyte demoparty!

Sharing this I saw on twitter by BrunoLevy01:
——
The simple #femtorv-quark takes no more than 200 lines of VERILOG. Yes, it is the complete description of a risc-v processor, that can run C programs compiled with gcc-riscv

The #FemtoRV Quark, a small #RISCV RV32I core developed by @BrunoLevy01 and me has been implemented in silicon by a team from Brazil:
https://github.com/FelipeFFerreira/ITA-CORESVery happy about that!
See the original processor source here:

Congrats @destevez, well deserved for #MaiaSDR !
Meanwhile @BrunoLevy01 and @sylefeb this might be of interest to you as, during the #SDR Academy conference ( #sdra https://2023.sdra.io/ ), they also call for more #FPGA people to submit for next year. A bit like when you Sylvain have presented #Silice to South Indian SDR User Group (SI-SDR-UG) https://youtu.be/fr4Dst1fQrk?t=10554

I am happy to announce the FemtoMSP430, a processor designed with the instruction set of the classic #MSP430, but with a flexible bus interface similar to @BrunoLevy01 #FemtoRV32 including memory busy signaling. The playground contains a phantasy "microcontroller" design for the #ULX3S #FPGA board, interactively running the original #Mecrisp #Forth image for MSP430G2755, enhanced with a text mode on 800x600 video, USB-CDC terminal and a lot of GPIO wires: https://codeberg.org/Mecrisp/FemtoMSP430

Found an excellent walkthrough video https://www.youtube.com/watch?v=8boamDdvD8s for the #FemtoRV-Quark https://github.com/BrunoLevy/learn-fpga/blob/master/FemtoRV/RTL/PROCESSOR/femtorv32_quark.v code! @BrunoLevy01 and me did our very best to make the Verilog source of our #RISCV RV32I processor core readable, and this video explains all the tricks involved in a very nice style with drawings.

Went with another classic, the dragon statue.
This shows triangulated surface remeshing using a (very basic) #JuliaLang wrapper for @BrunoLevy01 et al.'s fantastic Geogram library (https://github.com/BrunoLevy/geogram).

After Hours Engineering: SoC Episode 1: VGA and femto
We begin by covering a relatively simple VGA and finish off with a brief on the CPU (aka femto by @BrunoLevy01 )
Feel free to come along for the journey! 🙂

The space mission MAIUS-2 I wrote firmware for since 2019 launched in November 2023, and I am now open for new paid projects! My favourites are #Assembler, #Forth and #Verilog on #FPGA. I am the author of #Mecrisp, a family of optimising Forth compilers (Mecrisp-Ice went to space!), did processor design with @BrunoLevy01 (#FemtoRV Gracilis) and I love #sizecoding challenges (Byte-Athlon Champion in #Lovebyte 2023). Formally, I am Dr. rer. nat. in biophysics with experience in laser spectroscopy.

Four RV32I @risc_v cores totaling ~333M IPS do work with a 480p frame buffer 🤓. 20 threads, ~software rendering, but focus isn't on CPU core, next up: experiments with custom accelerator pipelines to offload compute 😏 #PipelineC
#FPGA #HDL #RTL #graphics #RISCV Thanks @BrunoLevy01 and friends! -
Under the hood: HUGE Laguerre diagrams (fig 1), used to compute the large sparse matrices (fig 2). Grid 5000/SLICES has nice "pocket calculators" (fig 3), so we played with them and obtained interesting timings (fig 4) on a smaller problem (120 million points). Can we do even better ? More to come.

Working on Scalable Optimal Transport with R. Mohayaee, C. Dapogny and E. Oudet:
more than 1 billion particles !
➡️ use algebraic multigrid preconditioner (AMGCL)
➡️ rewrite GPU backend: no limit on matrix size, supports multi-GPU !
➡️ Available in OpenNL: https://github.com/BrunoLevy/OpenNL -
This chip is special,
(https://tinytapeout.com/chips/ttsky25b/)- it has designs made by hobbyists
- and, more importantly, it has two #FemtoRV designs in it !!
- these two FemtoRV designs were authored by othersWhat is FemtoRV ? It is a super simple RiscV processor that we designed with @Mecrisp because we were boring during COVID...),
More information here:
https://github.com/BrunoLevy/learn-fpga/I am super excited, can't wait to see whether these 200 lines of VERILOG can be turned into a real Risc-V CPU on a chip !

I was considering tinkering with #femtorv to make it run on the device, but it seems that others already did it, it is part of the Apicula examples, here:
https://github.com/YosysHQ/apicula/blob/master/examples/femto-riscv-18.v
I'll try that tomorrow (let us call it a day for now) -
The traditional blinky was easy, let us see whether #femtorv flies...
