sen<p>Some discussions I had last week got me motivated to start working on my <a href="https://hachyderm.io/tags/homebrewcpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>homebrewcpu</span></a> again, and I have a good start at DMA support today!</p><p>Once DMA is done I need to figure out traps/faults, then I’m basically ready to call the architecture done. My goal is to finalize the architecture by next November, then start working on translating Verilog into 10K ECL! (and continue work on the LLVM port in parallel as my brain needs to think about something different)</p>

Futuristic Robert [KJ5ELX] :donor:<p>So I have started a <a href="https://infosec.exchange/tags/project" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>project</span></a> to build a home-brew <a href="https://infosec.exchange/tags/CPU" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CPU</span></a> from scratch using 74LS series ICs. This is the beginning of the first module. This board contains 6 8-bit registers which will result in 4 general purpose and 2 “transfer registers.” It will mate to another board that wil most likely be some sort of bus controller. I’m making this up as I go along, but it’s a project I’ve wanted to do for a long time. I expect tons of compromises and bodge wiring along the way but gotta start somewhere, and this purely for fun and learning. </p><p><a href="https://infosec.exchange/tags/homebrewcpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>homebrewcpu</span></a></p>
