Rev Log message Author Age Path
18 Finished memory controller earlz 4499d 02h /
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct
earlz 4499d 15h /
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 4502d 18h /
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4504d 15h /
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4504d 23h /
13 Forgot about the new library I added earlz 4505d 02h /
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD
earlz 4505d 03h /
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 4508d 16h /
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4508d 16h /
9 Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench earlz 4509d 00h /
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing
earlz 4510d 00h /
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 4510d 01h /
6 Reworked memory code to hopefully synthesize better earlz 4510d 05h /
5 Modified registerfile to be dual-port for both read and write earlz 4510d 16h /
4 Added internal memory interface
Updated design
earlz 4511d 00h /
3 Updated registerfile to have 2 read ports
Added super rough design document mainly just for brainstorming
earlz 4511d 16h /
2 Initial commit earlz 4511d 18h /
1 The project and the structure was created root 4511d 20h /
