CPU 2fe0518bb3 Improved interrupt timing/alignment, fixing bug where interrupts are not allowed during the UART bootloader. 1 an în urmă
GPU 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 an în urmă
IO 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 ani în urmă
Memory 9a285550c0 Updated documentation a bit, added newlines to BENCH, removed wrong comments from L2cache.v 1 an în urmă
DtrReset.v b74702c915 Created full FPGC6 verilog simulation, added Quartus code from FPGC5 with CPU from FPGC6. Works in hardware, but has combination loop somewhere at the arbiter and the registerbank and stack are not using block ram 2 ani în urmă
FPGC6.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 an în urmă
