DSP/BIOS是TI公司为其DSP量身打造的一套实时多任务操作系统。由于DSP/BIOS的移植过程较为繁琐,并且在TMS320C6000(简称C6000)系列DSP上移植过程较为复杂。为了解决这些问题,通过分析C6000系列DSP芯片的上电启动过程和DSP/BIOS程序启动的一般流程,提出了一种DSP/BIOS在C6000系列DSP芯片上通用自启动方法,然后对DSP/BIOS中存储段配置、链接命令文件操作以及不同RAM架构下二级BootLoader的实现进行了详细设计和说明,实现了DSP/BIOS工程在C6000系列DSP上自启动的通用方法。该设计已经成功应用在某多信号采集传输项目中。
Abstract
DSP/BIOS is a set of real-time multitasking operating system tailored by TI for its DSP.Because the transplanting process of DSP/BIOS is cumbersome,and the transplanting process on TMS320C6000 series DSP is more complicated.In order to solve these problems,by analyzing the power-on and startup process of C6000 series DSP chips and the general process of DSP/BIOS program startup,a general self-starting method of DSP/BIOS on C6000 series DSP chips is proposed.The configuration of storage segment,the operation of link command file and the realization of the second-level BootLoader under different RAM architectures are designed and explained in detail,and the general method of DSP/BIOS project self-starting on C6000 series DSP is realized.The design has been successfully applied in a multi-signal acquisition and transmission project.
