摘要: 针对TMS320C672x DSP引导装载过程开发困难的问题,提出一种新的引导程序开发方法。在单片机内,设计从RS232接口到DSP中的SPI接口的数据转换程序,实现PC直接与DSP通信,在PC上使用VC对引导程序进行编译。应用结果表明,该方法使开发过程更方便、快捷。

关键词: 数字信号处理器, 引导程序, RS232协议, SPI协议

Abstract: This paper proposes a novel bootloader development method, aiming at the problem of the difficulty in TMS320C672x Digital Signal Processor(DSP) bootloader load procedure development. In Micro Controller Unit(MCU), a data conversion program between the RS232 interface and the SPI interface in DSP is implemented to make PC communicate with DSP directly. The bootloader can be compiled on PC with VC. Application results show that this method makes the development process easier and faster.

Key words: Digital Signal Processor(DSP), bootloader, RS232 protocol, SPI protocol
