摘要
介绍了TI公司的实时操作系统(RTOS)内核DSP/BIOS,阐明了使用DSP/BIOS开发雷达目标检测系统的优点。先利用FPGA控制高速A/D对雷达视频数字化,然后使用DSP/BIOS内核构建多个数字信号处理线程,通过芯片支持库(CSL)配置外设资源,最后对程序进行实时分析和优化。从而大大降低了DSP系统开发的复杂度,缩短了开发周期,顺利实现了雷达目标自动检测等功能。
The article introduces the kernel of real time operation named DSP/BIOS by TI, and illustrates the superiority of using DSP/BIOS on developing the detection of radar objects system. First the system digitizes the radar video by the FPGA controlling the high speed A/D chips, then the kernel of DSP/BIOS can be used to design several digital signal process threading and Chip Support Library（CSL） can be utilized to configure peripheral equipment, at last using the real time analysis tools, we can analyze and optimize the digital signal processing program. The DSP/BIOS reduces the complexity of the DSP system developing, shortens the developing period and accomplishes the automatic detection of radar objects system.
