Rev	Log message	Author	Age	Path
26	Added extra check to make sure fetcher works properly after memory write	earlz	4389d 11h	/tinycpu/
25	Wait for memory state now works as expected, and opcode `mov [reg], immd` works now	earlz	4389d 15h	/tinycpu/
24	Good news, mov to IP actually works as expected!	earlz	4390d 09h	/tinycpu/
23	Added top module for testing how our memory and cpu will work together. (hint: success) Messing around with a small timing issue in core	earlz	4390d 09h	/tinycpu/
22	Added to process sensitivity list to avoid warning and added ELSE for IR so it doesn't generate a latch	earlz	4391d 01h	/tinycpu/
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	4391d 01h	/tinycpu/
20	fuck it. All sorts of broken, will try to fix it tomorrow	earlz	4392d 01h	/tinycpu/
19	Got beginning of core/decoder for the CPU	earlz	4392d 03h	/tinycpu/
18	Finished memory controller	earlz	4395d 12h	/tinycpu/
17	Added fetch component for fetching from memory to instruction register Added additional testing for carryover to make sure it's correct	earlz	4396d 02h	/tinycpu/
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	4399d 04h	/tinycpu/
15	Added README, LICENSE, and the (so far not created) incdec component	earlz	4401d 01h	/tinycpu/
14	Added ALU with all the operations we'll need. Synthesizes as well trivially	earlz	4401d 10h	/tinycpu/
13	Forgot about the new library I added	earlz	4401d 12h	/tinycpu/
12	registerfile has ports for every register now makefile now uses GHW file format for gtkwave instead of VCD	earlz	4401d 13h	/tinycpu/
11	Finally, it synthesizes to BRAM.. Possibly need to fix how the DataOut syncs with WriteEnable and Address though if I plan to both read and write on the same clock edge	earlz	4405d 02h	/tinycpu/
10	Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs	earlz	4405d 03h	/tinycpu/
9	Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench	earlz	4405d 10h	/tinycpu/
8	Added blockram for inferring actual block RAM. Now we need a memory controller, not a crappy memory emulation thing	earlz	4406d 10h	/tinycpu/
7	Changed memory to fix bound check error Decreased size of RAM since 4096 bytes of RAM would require an FPGA with more than 32K flip-flops (mine has ~4000)	earlz	4406d 11h	/tinycpu/
