computer

An 8-bit machine with 16 bits of address space. This is my attempt at virtual memory, access modes, and preemptive multitasking.

here it is running the multiple-handlers.asm program

the assembly program

; $ cat test.asm
.data
    page_table:
        .byte   0x00
    incrementor:
        .byte   0x00

.text
    main:
        vset    page_table
        cset    0x40
        clac
        stor    incrementor
    loop:
        add     incrementor
        addi    0x01
        stor    incrementor
        clac

assembles to the binary file

$ python assembler.py -f test.asm -o test
$ hexdump test
