Rev Log message Author Age Path
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct		 earlz 4429d 00h /tinycpu/trunk/src/
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 4432d 02h /tinycpu/trunk/src/
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4434d 00h /tinycpu/trunk/src/
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4434d 08h /tinycpu/trunk/src/
13 Forgot about the new library I added earlz 4434d 10h /tinycpu/trunk/src/
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD		 earlz 4434d 11h /tinycpu/trunk/src/
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 4438d 00h /tinycpu/trunk/src/
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4438d 01h /tinycpu/trunk/src/
9 Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench earlz 4438d 09h /tinycpu/trunk/src/
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing		 earlz 4439d 08h /tinycpu/trunk/src/
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 4439d 09h /tinycpu/trunk/src/
6 Reworked memory code to hopefully synthesize better earlz 4439d 14h /tinycpu/trunk/src/
5 Modified registerfile to be dual-port for both read and write earlz 4440d 01h /tinycpu/trunk/src/
4 Added internal memory interface
Updated design		 earlz 4440d 09h /tinycpu/trunk/src/
3 Updated registerfile to have 2 read ports
Added super rough design document mainly just for brainstorming		 earlz 4441d 01h /tinycpu/trunk/src/
2 Initial commit earlz 4441d 02h /tinycpu/trunk/src/
