- 3. Computer Architecture Instruction Types Data Transfer Instructions Arithmetic Instructions Logical Instructions Program-control Instructions System-control Instructions I/O Instructions
- 4. Computer Architecture Data Transfer Instructions Data-transfer instructions are concerned with data transfer between the processor and main memory. Register to register Register to memory Memory to register Memory to memory
- 5. Computer Architecture Arithmetic Instructions All instructions comprising of arithmetic calculations.
- 8. Computer Architecture Logical Instructions These instructions include Boolean AND, OR, NOT, EXCLUSIVE-OR and also shift operations.
- 9. Computer Architecture Program-control Instructions These instructions may be classified into fours groups Unconditional branch instructions Conditional branch instructions Subroutine call instructions Interrupt-handling instructions
- 10. Computer Architecture Program-control Instructions Unconditional branch instructions • JUMP • GOTO
- 11. Computer Architecture Program-control Instructions Conditional branch instructions If (condition) then branch to execute a new instruction else execute the following instruction.
- 12. Computer Architecture Program-control Instructions Conditional branch instructions
- 13. Computer Architecture Program-control Instructions Subroutine call instructions
- 14. Computer Architecture Program-control Instructions Subroutine call instructions
- 15. Computer Architecture Program-control Instructions Interrupt-handling instructions An interrupt may be defined as a hardware initiated subroutine call. For example in a microprocessor based system, an I/O device such as a keyboard may generate an interrupt to inform the processor the valid data is available.
- 16. Computer Architecture System-control Instructions Several processors sharing a single memory unit. Processor1 Processor2 RAM
- 17. Computer Architecture System-control Instructions Processor1 Processor2
- 18. Computer Architecture I/O Instructions I/O instructions allow a processor to perform input and output operations.
- 19. Computer Architecture Reduced Instruction Set Computer (RISC) Run fast Cost less Use set of simple instructions
- 20. Computer Architecture Assignment: Report Writing • Write a report not more than two pages • Topic “Is RISC better than CISC?”
