一个ARM7的应用程序-an ARM7 applications

arm7内核的verilog代码，可以综合，虽有几条指令没有实现，但已实现的功能对理解arm体系结构已足够-ARM7 core Verilog code can be integrated, although some commands do not realize, it has been achieved in understanding the functional architecture has enough arm

应用背景通过dma控制来读取ad信号，在很多传感器应用方面都能用到，比如压力传感器读取，温度读取等等而且用起来也十分方便。希望能帮助大家。关键技术读取ad信号，dma读取，嵌入式开发，不是位操作，看起来通俗易懂，而且开发容易，还包括一些其他信号的读取，如超声波，气压计，加速度计等等。

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.
