AT89C51SND1C是AT89C51核心的处理器，包含一个MP3解码器，完全兼容8051的Keil C51编译环境，适合8051使用者的MP3解码应用。本代码在基本代码基础上增加了LCD驱动部分，需要比较多的RAM和ROM资源，大家按照自己的系统资源情况，选择基本版本代码还是扩展LCD的代码。

Design patterns are elegant, adaptable, and reusable solutions to everyday software development problems. Programmers use design patterns to organize objects in programs, making them easier to write and modify. C# Design Patterns: A Tutorial is a practical guide to writing C# programs using the most common patterns. This tutorial begins with clear and concise introductions to C#, object-oriented programming and inheritance, and UML diagrams. Each chapter that follows describes one of twenty-three design patterns, recommends when to use it, and explains the impact that it will have on the larger design. The use of every pattern is demonstrated with simple example programs. These programs are illustrated with screen shots and UML diagrams displaying how the classes interact. Each of these programs is available on the companion CD-ROM and can be run, examined, edited, and applied.

Please read this document before attempting to compile and run the libraries and applications! The projects must be compiled in a particular order. Standard support questions are about compiler and/or linker errors that are generated when users try to compile the projects in the wrong order. Other information of interest is available here, so read the entire document fi rst. Wild Magic Version 2.1 is what ships with the fi rst printing of the Game Physics book. Some of the applications that are referenced in the book did not make it onto the CD–ROM for the book. Version 2.2 contains those applications, plus more

一个用自己写的编译器编译的操作系统内核. 有包含中断和不包含中断两个版本. 还有简单的用户应用程序。 因为该代码原目的是下载到硬件上使用，所以kernel必须限制在该硬件可接受的8k rom之内。作者对优化代码大小也下了相当的功夫。 为了保证程序可以运行，这里附带了编译该操作系统的编译器。

嵌入式系统的资源有限，应用程序通常都是固化在ROM中运行。ROM中的程序执行前，需要对系统硬件和软件运行环境进行初始化。这些工作是用汇编语言和C语言编写的Bootloader代码完成的
