- 4. History of (ISA) For the first time IBM introduce 360 in 1964. “An instruction set specifies a processor define storage limits and method of access.”
- 5. Instruction Set Architecture Instruction set architecture (ISA), is the part of the computer architecture related to instructions, registers, addressing modes, memory architecture, interrupt and external I/O
- 6. ISA semantically It is close to high level language. It is near to semantic gap. Semantically are heavy instructions such that RISC and CISC
- 7. Feature of ISA Implement ability is consider as a main part of ISA. It include performance and cost range. Programmability easy to express program efficiently.
- 8. Difference b/w RISC and CISC The difference b/w RISC(reduce instruction set computing) and CISC(Complex instruction set computing) is number of computing cycles each of their instruction take.
- 9. Computer set Architecture Computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems.
- 10. What is MIPS ? The number of MIPS (million instructions per second) is a general measure of computing performance.
- 11. Relation of complier and ISA The major purpose to generate the best code for machine. ISA can help the compiler by giving the best sequence of instruction
- 12. Advantage: Makes code generation easy. Dada can be stored for long periods is registers. The accumulator is only temporary storage so memory traffic is the highest for this approach
- 13. Disadvantage: All operands must be named leading to longer instruction.
