Mai :v_trans:<p>After getting a basic ALU design done yesterday &amp; starting a **very** rough start at a microcodeish thing, today the first design of the controlunit &amp; 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! :3</p><p>Still 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">#<span>hardware</span></a> <a href="https://soc.saiyajin.space/tags/fantasyconsole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fantasyconsole</span></a> <a href="https://soc.saiyajin.space/tags/diy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>diy</span></a> <a href="https://soc.saiyajin.space/tags/verilog" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>verilog</span></a> <a href="https://soc.saiyajin.space/tags/systemverilog" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>systemverilog</span></a> <a href="https://soc.saiyajin.space/tags/software" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>software</span></a> <a href="https://soc.saiyajin.space/tags/cpudesign" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cpudesign</span></a> <a href="https://soc.saiyajin.space/tags/hardwaredesign" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hardwaredesign</span></a> <a href="https://soc.saiyajin.space/tags/fpga" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fpga</span></a> <a href="https://soc.saiyajin.space/tags/fpgadev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fpgadev</span></a></p>
Tom Gambill<p>Baby steps in getting my Apple I reproduction PCB up and running. 6502 CPU booting with just RAM and ROM attached.
