]本文介绍了如何利用CPLD(复杂可编程逻辑器件)与单片机的结合实现并行I／ O(输入／输出)接口的扩展。该设计与用8255做并行I／O接口相比，与单片机软件完全兼容， 同时拥有速度快，功耗低，价格便宜，使用灵活等特点-] This article describes how to use the CPLD (complex programmable logic device) and the single-chip combination to achieve parallel I/O (input/output) interface expansion. The design and use 8255 to do parallel I/O interface as compared with the single-chip software is fully compatible at the same time have a fast, low power consumption and cheaper prices, the use of flexible features such as

虚拟机设计与实现源代码，很不错的源代码。至于书籍可到网上下载！-Virtual Machine Design and Implementation of source code, source code is pretty good. As for books can be purchased online at download!

This is a package to calculate Discrete Fourier/Cosine/Sine Transforms of 1-dimensional sequences of length 2^N. This package contains C and Fortran FFT codes.

试试,我不知道这里怎么弄.才来的.谁告诉我一下吧.-try, I do not know how get here. Only to come. Who told me about it. Thank you
