Provides storage internal to the CPU

control unit consists of

stores microprogram

stores instructions and data

User/Modified

System/ROM

A way to describe microoperations capable of being performed by the data flow (data registers, data buses, functional units) at the register transfer level of design (RT)

Also describes conditional information in the system which cause operations to come about

Register Transfer Notation is A “shorthand” notation for …..

The general format of an RTN statement:

The possible locations in which transfer of information occurs are

data flow

Arithmetic operations, Logic operations, Shifts operations are ….

have multiple processors

When these processors all reside on a single chip, the term multicore computer is used, and each processing unit (consisting of a control unit, ALU, registers, and perhaps cache) is called a core

A prominent feature of contemporary computers is the use of multiple layers of memory, called….. , between the processor and main memory

cache memory is smaller and faster than main memory and is used to speed up memory access

by placing in the cache data from main memory, that is likely to be used in the near future

A greater performance improvement may be obtained by using multiple levels of cache

level 3 L3 cache closest to the core

, level n is …. and …..than level n + 1
