A CPU+FPGA OpenCL Heterogeneous Computing Platform for Multi-Kernel Pipeline
A CPU+FPGA OpenCL Heterogeneous Computing Platform for Multi-Kernel Pipeline
I'm pondering 15-bit (5 bits per channel) colour for my #FPGA display logic instead of the current 12-bit.
I prefer 15 to 16-bit for true greys. 24-bit seems overkill and requires twice the storage.
A minor downside is the absence of the human-parseable hex values you get with 12-bit (0xFFC). π¨
Summer 2025 #cvut defended theses by OTREES / βmyβ students:
See the last OTREES theses list for link to repositories and more
Another related theses from #cvut Faculty of Information Technologies mentored by Michal Ε tepanovskΓ½ to mention:
Stay tuned next summer as well, there is student interesting in thesis to add MMU to #QtRvSim
Just pushed some updates. I have posted the #verilog serial link code. This involved getting a set of scripts for simulation set up.
If anybody is interested in helping on this project, I'd love to have somebody try to follow the readme.md to install the prerequisites and run the ./run_sim script.
The goal would be to take notes and flesh out what things aren't in the prerequisite list and how to install them.
I'd be happy to do the same for somebody else's project.

I am happy to announce the release of a longwave software defined radio which I designed at work for experiments with #DSP algorithms, running on the #ULX3S #FPGA board. The user interface is based on #Mecrisp #Forth running on the #FemtoRV, and the signal chain contains a pipelined FFT designed by Dan Gisselquist. Many thanks to Ulixxe for their USB-CDC implementation!

I was just reading about #frugalComputing and found myself thinking of #Precursor
It feels to me like it would be a good fit for something like #deltaChat

Dear #lazymastodon:
I'm trying to move an #FPGA simulation from Rivera-PRO to Tachyon cvc64 in #verilog
I have a design with four "top levels" and cvc seems to chose the first one in the compile order. I would like to specify one explicitly.
I'm using the open version of the tool, so don't have paid support.
Documentation for this tool is... hard to find?
Can someone recommend a better tool? Or just show me where I missed in the documentation how to set the top?
