在系统可编程通用数据下载器的设计与实现

Design and Implementation for an Interchangeasble ISP Data Downloading Unit

研究了在系统可编程（ISP）器件的功能定义数据下载的原理、规范，讨论了一种采用单片机控制的、接口可编程的ISP通用数据下载器硬件电路和软件程序的设计，为数字系统设计真正实现在系统可编程（ISP）提供了一种新的实用方法.

The fundamental and process of data downloading for ISP devices are discussed. An interchangeable ISP data downloading unit supported by a MCU is designed and implemented. The results provide an optimal solution for the real implementation of in system system programmable digital logic.
