Basic Terminologies Zelalem Birhanu, AAiT

9

Basic • Clock Cycle  Period of the U clock  The fundamental unit of time for U activity

• Instruction  A meaningful command to be executed by the U along with the data operands

•  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  -> 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 – U, 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
