9. Basic Terminologies
9Zelalem Birhanu, AAiT

10. 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

11. 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

12. 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

13. 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

14. Next Class
• 8086 Architecture
