Rev Log message Author Age Path
26 Added extra check to make sure fetcher works properly after memory write earlz 4468d 16h /tinycpu
25 Wait for memory state now works as expected, and opcode `mov [reg], immd` works now earlz 4468d 21h /tinycpu
24 Good news, mov to IP actually works as expected! earlz 4469d 14h /tinycpu
23 Added top module for testing how our memory and cpu will work together. (hint: success)
Messing around with a small timing issue in core
earlz 4469d 15h /tinycpu
22 Added to process sensitivity list to avoid warning and added ELSE for IR so it doesn't generate a latch earlz 4470d 06h /tinycpu
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 4470d 07h /tinycpu
20 fuck it. All sorts of broken, will try to fix it tomorrow earlz 4471d 06h /tinycpu
19 Got beginning of core/decoder for the CPU earlz 4471d 08h /tinycpu
18 Finished memory controller earlz 4474d 18h /tinycpu
17 Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct
earlz 4475d 07h /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 4478d 10h /tinycpu
15 Added README, LICENSE, and the (so far not created) incdec component earlz 4480d 07h /tinycpu
14 Added ALU with all the operations we'll need. Synthesizes as well trivially earlz 4480d 15h /tinycpu
13 Forgot about the new library I added earlz 4480d 18h /tinycpu
12 registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD
earlz 4480d 18h /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 4484d 08h /tinycpu
10 Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs earlz 4484d 08h /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 4484d 16h /tinycpu
8 Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing
earlz 4485d 15h /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 4485d 17h /tinycpu
