26 Added extra check to make sure fetcher works properly after memory write earlz 4513d 14h /
25 Wait for memory state now works as expected, and opcode `mov [reg], immd` works now earlz 4513d 18h /
24 Good news, mov to IP actually works as expected! earlz 4514d 12h /
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 4514d 12h /
22 Added to process sensitivity list to avoid warning and added ELSE for IR so it doesn't generate a latch earlz 4515d 04h /
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 4515d 04h /
20 fuck it. All sorts of broken, will try to fix it tomorrow earlz 4516d 04h /
19 Got beginning of core/decoder for the CPU earlz 4516d 06h /
18 Finished memory controller earlz 4519d 15h /
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct
earlz 4520d 05h /
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 4523d 07h /
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4525d 05h /
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4525d 13h /
13 Forgot about the new library I added earlz 4525d 15h /
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD
earlz 4525d 16h /
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 4529d 06h /
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4529d 06h /
9 Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench earlz 4529d 14h /
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing
earlz 4530d 13h /
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 4530d 14h /
