Rev	Log message	Author	Age	Path
25	Wait for memory state now works as expected, and opcode `mov [reg], immd` works now	earlz	4390d 00h	/
24	Good news, mov to IP actually works as expected!	earlz	4390d 17h	/
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 18h	/
22	Added to process sensitivity list to avoid warning and added ELSE for IR so it doesn't generate a latch	earlz	4391d 10h	/
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 10h	/
20	fuck it. All sorts of broken, will try to fix it tomorrow	earlz	4392d 10h	/
19	Got beginning of core/decoder for the CPU	earlz	4392d 11h	/
18	Finished memory controller	earlz	4395d 21h	/
17	Added fetch component for fetching from memory to instruction register Added additional testing for carryover to make sure it's correct	earlz	4396d 10h	/
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 13h	/
15	Added README, LICENSE, and the (so far not created) incdec component	earlz	4401d 10h	/
14	Added ALU with all the operations we'll need. Synthesizes as well trivially	earlz	4401d 18h	/
13	Forgot about the new library I added	earlz	4401d 21h	/
12	registerfile has ports for every register now makefile now uses GHW file format for gtkwave instead of VCD	earlz	4401d 22h	/
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 11h	/
10	Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs	earlz	4405d 11h	/
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 19h	/
8	Added blockram for inferring actual block RAM. Now we need a memory controller, not a crappy memory emulation thing	earlz	4406d 19h	/
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 20h	/
6	Reworked memory code to hopefully synthesize better	earlz	4407d 00h	/
