Rev	Log message	Author	Age	Path
27	Added a few ALU opcodes and came across a weird propogation delay issue with my registerfile. As a workaround, I'm trying to use falling_edge instead of rising_edge. We shall see if I regret this later	earlz	4399d 10h	/tinycpu/trunk/docs/
25	Wait for memory state now works as expected, and opcode `mov [reg], immd` works now	earlz	4399d 16h	/tinycpu/trunk/docs/
21	The core_tb testbench finally passes. It probably doesn't synthesize, or even pass other testbenches, but it passes that one damn it.	earlz	4401d 01h	/tinycpu/trunk/docs/
19	Got beginning of core/decoder for the CPU	earlz	4402d 03h	/tinycpu/trunk/docs/
17	Added fetch component for fetching from memory to instruction register Added additional testing for carryover to make sure it's correct	earlz	4406d 02h	/tinycpu/trunk/docs/
16	Renamed incdec to carryover (see design for why). carryover should be done, though may change the "straight through on disable" behavior to instead leaving it floating depending on how things go later with coding.	earlz	4409d 04h	/tinycpu/trunk/docs/
14	Added ALU with all the operations we'll need. Synthesizes as well trivially	earlz	4411d 10h	/tinycpu/trunk/docs/
5	Modified registerfile to be dual-port for both read and write	earlz	4417d 03h	/tinycpu/trunk/docs/
4	Added internal memory interface Updated design	earlz	4417d 11h	/tinycpu/trunk/docs/
3	Updated registerfile to have 2 read ports Added super rough design document mainly just for brainstorming	earlz	4418d 03h	/tinycpu/trunk/docs/
