New arbiter that further improves performance by removing latency for instruction memory access. Created instability again, which I found to be caused by bad interrupt timings. Fixed by changing the interruptValid wire to use branch_MEM for alignment. I do not know why this fixed all problems as it is very hard to simulate this issue. L1 cache should be possible again!

DataMem.v

Assembler only needs Int: function, fixed position of program lenght. Ported ROM and UART bootloader over from FPGC5. Updated documentation on interrupts. Added resets. Fixed bug in MU. Increased stack size. Tested everything in hardware. Probably some other fixes and things I forgot.

Fixed more MU I/O bugs. Updated everything from BCC except the ASM to work on new CPU. Added back flasher programs. Fixed LOAD/HI bug by using unsigned const16 instead. Updated assembler including hotfix for FPGC jumping to addr3 after UART bootloader is done. FPGC6 now basically fully works again!

Basic CPU design now done with afaik working hazard detection, forwarding and stalls. Tested in hardware on a EP4CE6 using two SSDisplays and dip switches to view the register content (and see if it matches the simulation). No interrupts yet as this can probably be done at a later stage.
