+GRU Devlog 13 - yemu, gasm and ocpu
+</title><description><![CDATA[
+
+<p>This week I have done several new instructions for yemu. For example all transfer instructions.</p>
+
+<p>Also I have rewritten gasm to support 6502, published it and it should help me with debugging yemu.
+It supports not very a lot instructions but I hope it is good start.</p>
+
+<p>But I think the coolest what I did this week is ocpu proccessor specification.
+Currently it is draft but i have already published it <a href="https://g1n.ttm.sh/gru/ocpu">here</a>.
+I hope this specifications will be Turing complete and we will try to implement it in real world.
+But firstly we need to make this specififcations complete, assembler and emulator for it.</p>
+
+<p>Also smlckz&rsquo;s idea was to make translator from ocpu assembler instructions to avr to emulate it on arduino!</p>
+

-<p>This week I was developing new OS - Orion.</p>
-
-<p>I don&rsquo;t understand very basic osdev thing so I decided to make OS on C and Asm.
-Currently that can just output text (with printf arguments) on screen and serial.
-Now gros is much cooler than Orion - it has input, interupts and a lot of else.
-But maybe I&rsquo;ll understand OSdev better.
-Currently working on GDT (global descriptor table) and than will work on
-interrupts and exceptions.</p>
