摘要
DSP处理器与FLASH存储器的接口设计是开发嵌入式系统的一项重要技术,本文采用一种简单可行的方法,通过TMS320F2812的外部空间XZCS6AND7信号线和FLASH的片选CE相连。在TI公司DSP集成开发环境CCS2.0下,通过JTAG口实现对DSP外部Flash可擦写存储器的烧写;将用户数据文件烧写到DSP的外部Flash中,并在TMS320F2812 DSP系统板上多次测试通过。
The design of interface between DSP processor and FLASH memorizer is important in embedded system. The paper introduces to use a simple way, link XZCS6AND7 of TMS320F2812 and CE of flash. Writing outside Flash by J-TAG interface which based on CCS2.0 of TI Company. User writes files data to outside Flash of DSP. At the same time, we have successfully test it to base on TMS320F2812 system board.
