20 fuck it. All sorts of broken, will try to fix it tomorrow earlz 4415d 09h /tinycpu/
19 Got beginning of core/decoder for the CPU earlz 4415d 10h /tinycpu/
18 Finished memory controller earlz 4418d 20h /tinycpu/
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct
earlz 4419d 09h /tinycpu/
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 4422d 12h /tinycpu/
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4424d 09h /tinycpu/
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4424d 17h /tinycpu/
13 Forgot about the new library I added earlz 4424d 20h /tinycpu/
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD
earlz 4424d 21h /tinycpu/
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 4428d 10h /tinycpu/
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4428d 10h /tinycpu/
9 Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench earlz 4428d 18h /tinycpu/
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing
earlz 4429d 18h /tinycpu/
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 4429d 19h /tinycpu/
6 Reworked memory code to hopefully synthesize better earlz 4429d 23h /tinycpu/
5 Modified registerfile to be dual-port for both read and write earlz 4430d 10h /tinycpu/
4 Added internal memory interface
Updated design
earlz 4430d 18h /tinycpu/
3 Updated registerfile to have 2 read ports
Added super rough design document mainly just for brainstorming
earlz 4431d 10h /tinycpu/
2 Initial commit earlz 4431d 11h /tinycpu/
1 The project and the structure was created root 4431d 14h /tinycpu/
