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.

Register forwarding now works for ALU operations, (memread getintid and savpc still needs forwarding). Regbank is simplified because no need for we_high anymore, load and loadhi are now done using an ALU operation.

Jump flush now seems to work. Made simple Quartus project to test in hardware and it seems to work fine there as well

Started working on the CPU pipeline. Basic load, arith and jumps seem to work now. No hazard handling yet.
