Mai :v_trans:After getting a basic ALU design done yesterday & starting a **very** rough start at a microcodeish thing, today the first design of the controlunit & overall cpu design comes together, so it can actually calculate an addition from two arbitary registers and store the result back into a register of choice! :3Still a lot to go but excited it works already somewhat! <a href="https://soc.saiyajin.space/tags/hardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hardware</a> <a href="https://soc.saiyajin.space/tags/fantasyconsole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fantasyconsole</a> <a href="https://soc.saiyajin.space/tags/diy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#diy</a> <a href="https://soc.saiyajin.space/tags/verilog" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#verilog</a> <a href="https://soc.saiyajin.space/tags/systemverilog" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#systemverilog</a> <a href="https://soc.saiyajin.space/tags/software" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#software</a> <a href="https://soc.saiyajin.space/tags/cpudesign" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cpudesign</a> <a href="https://soc.saiyajin.space/tags/hardwaredesign" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hardwaredesign</a> <a href="https://soc.saiyajin.space/tags/fpga" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fpga</a> <a href="https://soc.saiyajin.space/tags/fpgadev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fpgadev</a>
