01: Introduction to Computer Architecture

Costs, Power, Performance Budgets

what does a computer architect actually decide, map software needs onto hardware within

Architecture

the visible hardware-software contract

Microarchitecture

the logical arrangement of components

Microarchitecture

specific implementation of the ISA many _ implement the same x86 ISA

Organization

another name of microarchitecture

One memory

Von Neumann Architecture, stored-program, instructions and data share _ _

Fetch, Decode, Execute

Von Neumann Architecture, cycle

CPU and Memory Unit

arrows between _ _ _ _ are the potential bottlenecks

Harvard Architecture

separate memories and paths for instructions and data

Harvard Architecture

L1 instruction, data caches

modern CPU’s are “Harvard inside”, split _ _ and _ _ over one shared main memory

DSPs and Microcontrollers

Harvard architecture, true Harvard

Digital Signal Processor
