大多数电子系统的核心是处理数字输入、产生增值输出的处理器。通常一个系统的首要决策就是选择什么样的处理方案。处理方案确定之后,就要选择正确的驱动器和接收器。本文将介绍有关在驱动器和接收器的选择方面,应注意的问题。要求规定在选择处理器时,要综合考虑时钟频率、内存 At the heart of most electronic systems are processors that process digital inputs and produce added-value outputs. Usually a system’s first decision is to choose what kind of treatment options. Once the solution is finalized, it is necessary to select the correct driver and receiver. This article describes the issues to be aware of in selecting drives and receivers. Requirement in the choice of processor, we must consider the clock frequency, memory
