<h1>LOLcpu - my try to implement <a href="https://g1n.ttm.sh/gru/ocpu">GRU ocpu</a></h1>
<p>This is going to be something like log, where I am sharing some thoughts about electronics or circuits what I have done</p>

<h2>Some thoughts about first big cpu goal</h2>
<p>I think it will be unreal to implement ocpu specs in tiny amount of time, it may take ages.</p>
<p>So i decided to start from something easier.</p>
<p>My idea is to make cpu that have program counter, instruction register, and one general purpose register.</p>
<p>It will have 4 instructions - CLR, INC, DEC, FLR. CLR is instruction to set all zeros to general register.</p>
<p>INC and DEC is incrementing and decrementing its value. And FLR is too set maximum of that register (all ones).</p>
<p>I think that register should be at least 2-bit (but 4-bit mostly recommended), to know that it is working :)</p>
