22 Added to process sensitivity list to avoid warning and added ELSE for IR so it doesn't generate a latch earlz 4496d 17h /
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 4496d 17h /
20 fuck it. All sorts of broken, will try to fix it tomorrow earlz 4497d 17h /
19 Got beginning of core/decoder for the CPU earlz 4497d 19h /
18 Finished memory controller earlz 4501d 04h /
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct
earlz 4501d 18h /
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 4504d 20h /
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4506d 17h /
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4507d 02h /
13 Forgot about the new library I added earlz 4507d 04h /
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD
earlz 4507d 05h /
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 4510d 18h /
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4510d 19h /
9 Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench earlz 4511d 02h /
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing
earlz 4512d 02h /
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 4512d 03h /
6 Reworked memory code to hopefully synthesize better earlz 4512d 08h /
5 Modified registerfile to be dual-port for both read and write earlz 4512d 19h /
4 Added internal memory interface
Updated design
earlz 4513d 03h /
3 Updated registerfile to have 2 read ports
Added super rough design document mainly just for brainstorming
earlz 4513d 19h /
