    • 摘要: 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。

    • 摘要: 以数字信号处理(Digital Signal Processing,DSP)平台实现图像处理的应用开发一般较复杂,不利于复杂背景下弱小目标的检测.为提高检测程序执行的高效性和稳定性,提出了基于DSP/BIOS图像处理的弱小目标检测方法.该方法以高性能数字媒体处理器DM642为核心,以DSP/BIOS内核和动态调用API函数为辅助,以工业现场复杂镁熔液中弱小目标检测为载体,并通过数字I/O口的输出信号来判断检测的目标.经过不同条件下400次实验结果表明,综合检测率高达90.5%,与单线程DSP检测算法相比,检测率提高了11.04%,检测程序的执行效率和稳定性都得到提高.%The application and development of image processing methods that are based on the digital signal processing platform aregenerally complex processes;theseare also not feasible for the detection of weak and small targets in a complex background. In order to improve the efficiency and stability of a detection program, a method for the detection of weak and small targets based on DSP/BIOS image processing was proposed. In this method, the high performance of the digital media processor DM642 was considered to be the core, and the DSP/BIOS kernel and dynamic call API function were the auxiliary modules.Weak and small targets were detected in an industrial scenario where magnesium melt was used as the carrier in a complex background;the estimated target was determined by observing the output signal of the digital I/O. The results of 400 experiments under different conditions showed that detection rate was 90.59%, which is 11.04% higher than thatof a single thread DSP detection algorithm; moreover, the efficiency and stability of the detection program also improved.

    • 摘要: 在跳频通信系统中,跳频图案生成大多基于FPGA实现。提出了一种新的基于DSP生成跳频图案的方法。分析了DSP/BIOS的启动过程和DSP定时器工作原理,通过对DSP定时器计数器的控制,利用定时器中断生成跳频周期,进而生成跳频图案。对方法的实现结果进行了测试,给出了分别采用CLK和PRD模块实现时的跳频周期曲线,分析了测试结果,指出采用CLK模块更有优势,可以满足系统设计需求。%In the implementation of frequency hopping system, frequency hopping pattern is usu-ally generated based on FPGA. A new frequency hopping pattern generation method is proposed here, based on DSP. The startup procedure of DSP/BIOS is analyzed at first, then the working principle of the DSP timer is too. Through the control of DSP timer counter, the frequency hopping period is generated using the timer interrupt. So the frequency hopping pattern is gener-ated. The results of this method are tested and given, including the frequency hopping period curves separately using DSP/BIOS’ s CLK and PRD modules. With the analysis of the results, it is pointed out that CLK module is better over PRD module in the frequency hopping pattern gen-eration. The method can meet the system design requirements.
