This is a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program. All written in masm assembler. There is also a small 252 byte driver that allows nonstandard floppy formats on dos systems below 7.0. Floppies can be formatted in any track and sector layout. 1.44M floppies can be formatted to 1.76 M. All source code,includes and libraries are included. Modify the bld.bat file to your own needs. There are many asm tricks in the source code. Have fun with this old code.

这是我一个DSP实习,用汇编语言编实现离散余弦变换(DCT)的DSP程序设计。它有详细的设计流程、仿真结果,有完整的模块源码。其中有工程文件,和一个WORD文档,相信能让你清新的了解设计过程,掌握汇编设计离散余弦变换!

Like many of my colleagues in this industry, I learned Windows programming from Charles Petzold s Programming Windows—a classic programming text that is the bible to an entire generation of Windows programmers. When I set out to become an MFC programmer in 1994, I went shopping for an MFC equivalent to Programming Windows. After searching in vain for such a book and spending a year learning MFC the old-fashioned way, I decided to write one myself. It s the book you hold in your hands. And it s the book I would like to have had when I was learning to program Windows the MFC way.
