简要介绍了Franklin C51交叉编译器的特点，较详细地讨论了C51语言程序设计的基本技巧及其与汇编语言程序的混合编程、中断处理过程等实际问题，并给出了相应的处理程序。-this article introducede the point of C51 across compiler,and discussed the essence skill of C51 programmer.

在微型计算机系统中, CPU与外部的基本通信方式有两种,一种是并行通信即数据的各位同 时传送,其优点是传输速度较快,但数据有多少位就需要多少条传送线 而串行通信中数据一位一位顺序传 送,能节省传送线. 用Verilog HDL语言实现了串并、并串通信接口之间的转换-In the micro-computer system, CPU and the outside of the basic means of communication there are two types of parallel data communication that is transmitted at the same time you have the advantage of faster transfer speeds, but data on the number of those who need the number of transmission line and string A line of data communications, a sequence of transmission, transmission lines can be saved. using Verilog HDL language and realize the string, and string conversions between the communication interface

详细描述了存储器的基本结构，从最简单的单位存储单元到复杂的SDRAM,是软硬件设计师的最佳参考-Described in detail the basic structure of memory, from the simplest unit of memory cells to complex SDRAM, is the best reference software and hardware designers
