Rev Log message Author Age Path
18 Finished memory controller earlz 4509d 12h /tinycpu
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct		 earlz 4510d 02h /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 4513d 04h /tinycpu
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4515d 01h /tinycpu
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4515d 10h /tinycpu
13 Forgot about the new library I added earlz 4515d 12h /tinycpu
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD		 earlz 4515d 13h /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 4519d 02h /tinycpu
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4519d 03h /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 4519d 10h /tinycpu
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing		 earlz 4520d 10h /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 4520d 11h /tinycpu
6 Reworked memory code to hopefully synthesize better earlz 4520d 16h /tinycpu
5 Modified registerfile to be dual-port for both read and write earlz 4521d 03h /tinycpu
4 Added internal memory interface
Updated design		 earlz 4521d 11h /tinycpu
3 Updated registerfile to have 2 read ports
Added super rough design document mainly just for brainstorming		 earlz 4522d 03h /tinycpu
2 Initial commit earlz 4522d 04h /tinycpu
1 The project and the structure was created root 4522d 06h /tinycpu
