bart 69d109e653 Added hardware signed and unsigned integer division and modulo. Created simple integer calculator to test. Updated several programs and BDOS to use new division hardware while keeping software calculation as legacy functions. 1 год назад

L1Dcache.v add43b75da L2 cache at 100MHz now greatly increases performance. Attempted to create l1i and l1d cache, but becomes unstable and the issue is difficult to similate/replicate. Therefore, all l1 cache is now bypassed and the code can be found in l1cacheUnstable.v. As no l1 cache anymore, I removed some ccache statements to increase performance as this instruction currently does nothing. 1 год назад

ROM.v 55f619efae Initial commit with some empty Verilog template code from FPGC5 2 лет назад
SDRAMcontroller.v 28bcde6466 New SDRAM controller that uses both SDRAM chips. Now separate bus from MU for better performance, as controller runs at 100MHz. Also updated some debug code as debugging was needed. Tested working in hardware. 2x performance boost in some cases. 1 год назад
SPIreader.v 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 лет назад
VRAM.v 6dc8fc396f Added Pixel Engine in simulation. 2 лет назад
