Basic Terminologies

9Zelalem Birhanu, AAiT

Basic

• Clock Cycle

Period of the CPU clock

The fundamental unit of time for CPU activity

• Instruction

A meaningful command to be executed by the CPU along with the data operands

• Register

The fastest temporary data storage in the memory hierarchy

• ALU

A digital logic circuit to process logic and arithmetic

Basic

• Memory

A device used to store programs (instructions) and data

One of the basic elements of a computer

• Memory Hierarchy

Register -> Cache -> RAM -> Disks

• Cache

Fast, static memory to hold most frequently used data/instructions

Systems

• Microprocessor

Control only, external memory and I/O required

8086, M68000, MIPS, SPARC, Pentium, ARM7…

• Microcontroller

Integrated control, memory and I/O on a single chip

AVR, PIC, 8051, MSP, Coldfire, LPC…

• Microcomputer

Complete systems – CPU, Memory, I/O,…

PC, Mac, VAX, PDP, SunSparc

Arch

• CISC

Complex instructions, Simpler compiler, complex and large hardware

• RISC

Few and simple instructions, complex compilers, small and simple hardware

• Pipeline

A structure just like a product assembly line

Process the next task while the current one is in progress

Next Class

• 8086 Architecture
