TFTD: Half the battle with bitmap graphics is address calculation.

Looking promising. Here the #riscv CPU is updating the text scrolling register. There’s CDC from system to pixel clock domain. #FPGAFriday

Well, it works in simulation with one clock domain. But will 🏝️ Isle.Computer hardware registers work on real hardware with two clock domains? 🤔 #FPGA

Yikes. .io is expensive these days. But I’d be sad to retire projectf.io.

“We appreciate the community’s candid feedback” 😆

Good news! AMD listened. Linux will be supported by the basic ($0) version of #Vivado: https://adaptivesupport.amd.com/s/question/0D5Pd00001aT5IcKAK/adding-linux-support-back-for-the-basic-free-version-of-vivado?language=en_US

Merged improvements to Isle.Computer hardware register timing, canvas (bitmap) address generation, and docs. #FPGA

I still have much to learn about cocotb. You can see my cocotb test for the canavs display address here: https://github.com/projf/isle/blob/main/hardware/tests/gfx/canv_disp_agu.py

I've uncovered and fixed a bug in my graphics scaling hardware. My room temperature's down 3ºC on last night. Good times.

Contrast this with AMD's approach to GPU. ROCm is not only free on Linux, it's increasingly open source, even though it's targeting professional GPU compute users. https://www.phoronix.com/news/AMD-rocprof-trace-decoder
AMD Makes rocprof-trace-decoder Open-Source

AMD open-sourced the ROCprof Trace Decoder 'rocprof-trace-decoder', a tool useful for developers targeting the AMD GPU compute stack.

All recent dev teams I've worked with in hardware and software have been Linux/Mac. AMD should be releasing a free version of #Vivado for Linux and macOS.

Imagine if AMD charged $1000+ to compile software on Linux.

The only people hurt are hobbyists and the future of #FPGA outside big enterprises.
