NanoProc

NanoProc is a Fantasy Computer. It consists of a 32-bit fantasy CPU with a fairly flexible instruction set.

The following is example assembly code to loop through the numbers 0 through 100 then halt the computer:

            MOVE  $ACC,   0  ; Initialize register ACC to 0
loop_begin: CMPGE $ACC, 100  ; Compare if register ACC is greater than or equal
                             ; to 100
            JUMPC loop_end   ; If the previous condition was true jump to the end
                             ; of the loop
            INC   $ACC       ; Increment register ACC by 1
            JUMP  loop_begin ; Jump to beginning of loop
loop_end:   HALT             ; Halt CPU execution

nanoproc's Issues

Finish Assembler

Finish the Parser
Implement Simple directives (ie. DATA, DATA_BUF, DATA_STR, OFFSET)
Implement Complex directives (ie. INCLUDE, MACRO/ENDMACRO, SECTION)

Finish initial round of virtual hardware

Implement np-term; a Terminal-only video display for the computer (uses BearLibTerminal for graphics)
Implement np-tick; a hardware Clock for performance measurement and future task-switching
Implement np-clock; a hardware Clock for retrieving wall-clock times
Implement np-disk; a virtual hard disk drive for permanent storage
Anything unforseen?
