| 摘 要： | 介绍了板上编程（OBP）技术的基本原理。在实现上，以Atmel的高性能AVR单片机ATmega16L为核心。通过Philips的USB1.1控制芯片PDIUSBD12和上位机高速传输编程数据，同时，将组织好的数据并行发送给Altera的EPM240，由其产生JTAG时序，通过TAP（Test Access Port）与边界扫描（Boundry-Scan）技术，控制目标系统上微处理器引脚信号，最后完成与数据总线相连的FLASH存储器编程。

| Abstract: | The On-Board Programming technology is introduced. Taking Atmel's high-performance MCU Atmega16L as processing core and using Philips's high speed Universal Serial Bus(USB 1.1) peripheral controller PDIUSBD12 to communicate with PC. EPM240 generates JTAG timing. Based on Test Access Port and Boundary-Scan technology, the voltage level on pin of object processor is controlled by EPM240. At last,the flash memory connecting to processor is programmed. |
