CPU CHAPTER 3

Alu cpu

perform basic math used to connect core and L cashe

1L cashes

smaller faster memory

2L cashes

a larger slower than 1 from cpu

3L cashes

largest/furthers memory from cpu

D-ram

slower ram chipper used in L3 cashes

component that stores data is

ram

type of ram is used for main system memory/ ACTIVALLY DATA CPU USE

D-RAM

single CORE

a one processing core

Multicore processor

two or more processing core

Hyper-threading

a single core doing two task at the same time all this for improving performance

passive cooling

sitting and doing nothing

active cooling

by moving air

liquid cooling

using liquid to pull heat out of the system into water moving in a close loop

Thermal paste

paste used to fill in gaps and provide better heat transfer between to parts

throttling

slowing down the system during a lower power states or when its over heating

SRam

faster than dram used in L1/L2 cashe

front side bus

bus that connects the cpu it external memory what is it

MULTIPLIER

clock signal is multiplied to get the cpu speed set automatically

1 Hertz HZ

ONE Cycle per second

1 megahertz MHZ

ONE MILLION CYCLES PER SECOND

1 GigaHertz ghz

1 BILLON CYLES PER SECOND
