Computer Systerm Architacture的结构介绍

I only record the most important informations which are unkown or easily forgotten for myself.

Computer systerm is composed of hardware and software.

RAM（Random Access Memory）is storage for instruction and data. The reason why it is called RAM is that CPU could access any location in memory at random and retrieve the binary information within fixed interval of time.

逻辑门(Logic Gates)

There are 8 types logic gates which consists of AND, OR, NAND, NOR, BUFFER, INVERT, EXCLUSIVE-OR(XOR), EXCLUSIVE-NOR.

XOR’s output is 1 if any input is 1 but excludes the combination when both input are 1.

EXCLUSIVE-NOR’s output is a invert of XOR.

逻辑运算

Notice: x+yx=(x+y)(x+z)

MAP SIMPLIFICATION

Karnauph map(K-MAP) shows up in this chapter.

n variebles will have 2^n minterms

The way to get the correct formulation of the K-MAP is illustrated in followered graphs, and Don’t Care Conditions is in it too
