  bart b6831c4209 Added L2 cache (no L1 for now) between CPU and SDRAM controller. No noticable performance difference, can likely be optimized further to reduce cache hit latency. 1 жил өмнө
  bart 69e83fb855 Fully implemented interrupts in verilog. Return address appears to work fine, but might need some further testing for different delays in the pipeline. 2 жил өмнө
  bart e493a27ab4 Started on interrupts. Triggering seems to work, reti still needs to be implemented 2 жил өмнө
  bart 9662964536 Added back scripts for converting to spi.txt. Tested code to run from SPI flash, fixed cycle delay for SPI flash in output latch in MU which caused the bus_q to arrive a cycle later than bus_done. 2 жил өмнө
  bart 0e533922fb Connected instruction memory to the MU via the arbiter 2 жил өмнө
  bart 916054063a Added MU from FPGC5, created arbiter to regulate access to the CPU memory bus from both Instruction and Data memory, created fast testbench for arbiter, can now start adding arbiter and MU to CPU design 2 жил өмнө
  Bart fb0e4b363f Instruction memory can now have a delay without messing up the pipeline 2 жил өмнө
  Bart 3714a90401 Forwarding now also works for data memory and also probably branches and other MEM operations. Fixed a bug in forwarding where EX was used instead of WB 2 жил өмнө
  Bart 9da01544e7 Jump flush now seems to work. Made simple Quartus project to test in hardware and it seems to work fine there as well 2 жил өмнө
  Bart a76e895a39 Started working on the CPU pipeline. Basic load, arith and jumps seem to work now. No hazard handling yet. 2 жил өмнө
  Bart 7b0a44b7be Added testbench template with gtkw config 2 жил өмнө
  Bart 55f619efae Initial commit with some empty Verilog template code from FPGC5 2 жил өмнө
