COMPUTER OR GANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION

A multicore computer, also known as a chip multiprocessor, combines two or more
processors (called cores) on a single piece of silicon (called a die). Typically, each
core consists of all of the components of an independent processor, such as registers,
ALU, pipeline hardware, and control unit, plus L1 instruction and data caches. In
addition to the multiple cores, contemporary multicore chips also include L2 cache
and, increasingly, L3 cache.
