CPU-Sim

A Simplified Visualisation of a 16 bit CPU core with a custom instruction set

Instruction Set

1. NOP No operation
2. LDA <Address> Load address into accumulator
3. LDI <Unsigned Byte> Load immediate into accumulator
4. STA <Address> Store accumulator into address
5. ADD <Address> Add accumulator
6. SUB <Address> Subtract accumulator
7. MUL <Address> Multiply accumulator
8. DIV <Address> Divide accumulator
9. JMP <Address> Jump
10. JGZ <Address> Jump if greater than zero
11. JLZ <Address> Jump if less than zero
12. JEZ <Address> Jump if equal to zero
13. JNZ <Address> Jump if not equal to zero
14. INP Input to accumulator
15. OUT Output to accumulator
16. HLT Halt
