CCS环境两次编程实现DSP串行EEPROM自举的方法

The Method Realizing DSP Serial EEPROM Bootload By Twice Programming in CCS Environment

针对TI公司TMS320VC54系列DSP处理器独立运行需要程序自举引导的问题,介绍了一种利用CCS软件两次编程实现DSP通过SPI串行EEPROM完成程序代码自举的方法,给出了相应的硬件设计和软件编程思路,及以该方法实现DSP自举的实验。该方法硬件设计简单、成本低,而软件两次编程设计又方便DSP系统的在线编程调试和软件升级,可广泛用于程序代码不超过64K字节的DSP系统中。

In view of the problem for stand - alone TMS320VC54 family DSP of Texas Instruments Incorporated to boatload program, one kind of method with which DSP SPI serial EEPROM boofload can be realized by twice program in CCS software is introduced, and the corresponding hardware design and software programming mentality are given, as well as a DSP bootload experiment with the method. Hardware design of this method is simple and the cost is low. Software design of this method by twice program is convenient for on - line programming, debugging and software upgrade. The method can be widely used in DSP systems with no more than 64K bytes code.
