computer archicture

Common goal for computer designer:

• maximizing performance and minimizing cost and energy.

• Energy

• maximizing performance

• No one

• Instruction set:

• • the set of commands understood by a given architecture

• • words of computer's language

Defining ISA :

• Defines registers

• Defines registers Ana data transfer

• No one

Types of ISA :

• Complex instruction' set computer (CISC)

• Compelex (Cisc) and reduced (risc)

• Stack and gpa

Example of Reduced instruction

• ARM, MIPS

• Intel ×86

• Simple instructions, each executes in one clock cycle almost

• RISC

• Cisc

Arithmetic Logic Unit

• Gpr

• ALU

Top-down apparch

• High level - assembly- machine code

• Machine code - asmmbly - high level

The mips

• • (Microprocessor without Interlocked Pipelined

• • (Microprocessor without Interlocked Pipelined
    Stages

• MIPS very typical of other ISAs

• T

• F
