多核数字信号处理(DSP)芯片给信号处理能力带来了质的提升,TI公司推出的TMS320C6678是一款具有代表性的高性能多核DSP芯片。引导技术是DSP应用的关键技术之一。C6678有着丰富的外设接口,可选择多种引导设备,同时由于多核的存在,引导过程变得更为复杂。文中对C6678的引导方式进行了透彻的研究,介绍了C6678多核引导过程的具体实现步骤,对C6678引导程序的开发提供了实际的方法和经验。

Multi-core drgital signal processing (DSP) brought a quality improvement to the signal processing capabilities. The TMS320C6678 DSP presented by Texas Instruments (TI) is a representative high-performance multi-core DSP. Boot technique is one of the key techniques of the DSP's application. C6678 has various peripheral interfaces and can select different boot devices. Owing to this and the existence of multiple cores, it's boot procedure is considerable complex. This paper gave a deep research on boot modes of C6678, discussed the specific boot steps of C6678's eight cores, providing practical methods and experience to the developing of C6678 boot programs.
