PPT-Multiprocessing

Duocore processors What is Multiprocessing The use of more than one Central Processing Unit CPU with a single computer system to perform tasks In multiprocessing most if not all CPUs perform the same function however some may be reserved for a different function. g 03 Canonical example GPUs MIMD Multiple Instruction Multiple Data Ie 2 or more semiindependent CPUS 3 13 SIMD and MIMD Multiple CPUs come in several 64258avors SIMD Single Instruction Multiple Data Also called vector processor Sample instruction a What we sort of assumed so far…. Northbridge connects CPU and memory to rest of system. Memory controller implemented in Northbridge chipset. Devices and CPU can access memory via requests to Northbridge. Chak. Yee. How are SSDs involved?. File I/O slowest when seeking and writing to hard drive.. SSDs don’t have platters or mechanical heads, thus eliminates seek time.. . Single vs. Multithreaded Read.
