bart da2bff2ea2 Removed/disabled NTSC from design, as the tiny HDMI monitor is practically always used. Also greatly increased L2 cache size, although no performance benefits for the relatively small programs I currently use for benchmarking. 1 år sedan

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 år sedan

MemoryUnit.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 år sedan
ROM.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 år sedan
