Yesterday, I discovered a 959416035780 byte log file on a client server. Enough to write a post about every year the Universe has existed.

If you're writing assembler, I heartily recommend Compiler Explorer. I wrote about this from a RISC-V perspective a while back. #asm #riscv

All being well, I'll release the next installment of 🏝️ Isle #FPGA computer this Friday, in time for Halloween. Here's a colour reference graphic I created for the included palettes (you can create your own too).

I realise I've been a little quiet on the 🏝️ Isle #FPGA computer over the last month, but I've been beavering🦫 away on the 2D drawing engine, including 8 new Verilog modules, docs, tests, and a blog post. You can see a screenshot from the draft blog post below. More news soon…

Over the weekend I released the next part of Isle #FPGA Computer covering bitmap graphics.

I've added more docs and tests, but I'm still finding the right approach to the Isle blog and working on diagrams.

I'm getting to grips with more cocotb tests for Isle #FPGA computer. This new test verifies pixel output end-to-end: address_calc > vram > clut > display. We're not letting any latency issues sneak in. Will be part of chapter 2: bitmaps.

Part of the Isle #FPGA computer project is explaining my design choices. I hope this is interesting and aids you when working on your own hardware. In the display modes post, I explain why I'm supporting 1366x768, 1024x768, and 1280x720: projectf.io/isle/display...

Icepi Zero looks like an interesting open-source ECP5 #FPGA dev board. It’s got a decent spec in a small form factor. The only obvious omission is audio out. The big question is, how much will it cost? www.crowdsupply.com/icy-electron...

I don't yet have a complete system to share with you. Getting the design right takes a lot of experimentation; I've hit dead ends several times. I'll gradually introduce components over the coming months. The first part looks at display signals. #FPGA 📺 projectf.io/isle/display...

New #FPGA project from me this Friday. Just been validating the HTML and running some final tests. I thought it was time I nailed my colours to the mast. 🚀

My MacBook Air battery life has sucked recently, and it occurred to me to check if I'd left a Verilator simulation running. Instead, I found dot(1) with over 1500 minutes of CPU time!

We've tested 2, 4, and 16 colours, so why not 256? All colour depths supported by the 32-bit bram design with bit (sic) write. 32 x ECP5 brams is 64 KiB, which fits nicely in 25F+. Shown here with ULX3S #FPGA dev board.
