Document Summary

Lecture 1 (jamie mitchell: you have decided to buy a new portable device (tablet/laptop) and are comparing several options. Discuss four (4) characteristics you should consider when comparing their cpus. Amount of cores (multi, dual, or quad) Graphics processing unit (gpu) - processor that displays images. Processing speed - measured by cpu"s clock speed. Cache memory - special group of fast circuitry (faster processing: describe moore"s law, including future challenges and potential solutions. Gordon moore predicted that the number of transistors per square inch on chips had doubled every 2 years and the trend would continue. Physical limits to the amount a chip can hold, expensive. Modern day chips can be 3d and stacked: describe four (4) components of a cpu, and how they relate to the machine cycle. Decode - the arithmetic/logic unit (alu) performs arithmetic involving integers and logical operations (decodes instructions) Execute - instructions are carried out (bus interface unit - allows core communication)
