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 4575d 22h /
20 fuck it. All sorts of broken, will try to fix it tomorrow earlz 4576d 22h /
19 Got beginning of core/decoder for the CPU earlz 4576d 23h /
18 Finished memory controller earlz 4580d 09h /
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct
earlz 4580d 23h /
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 4584d 01h /
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4585d 22h /
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4586d 07h /
13 Forgot about the new library I added earlz 4586d 09h /
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD
earlz 4586d 10h /
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 4589d 23h /
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4590d 00h /
9 Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench earlz 4590d 07h /
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing
earlz 4591d 07h /
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 4591d 08h /
6 Reworked memory code to hopefully synthesize better earlz 4591d 13h /
5 Modified registerfile to be dual-port for both read and write earlz 4592d 00h /
4 Added internal memory interface
Updated design
earlz 4592d 08h /
3 Updated registerfile to have 2 read ports
Added super rough design document mainly just for brainstorming
earlz 4593d 00h /
2 Initial commit earlz 4593d 01h /
