摘要
针对嵌入式天文导航系统,介绍了由两片 TMS320C6701 组成的双 DSP 应用硬件平台。每个 DSP 外围扩展了多种存储器,采用双端口 RAM 技术进行数据传递,流水线处理特点使得 DSP 的运算速度极快,双 DSP 还可以将整个系统运算速度大大提高。该硬件平台运算速度快、体积小,完全适用于运算复杂的嵌入式天文导航系统。
In view of the embedded celestial navigation system, a hardware platform composed of two TMS320C6701 digital signal processors is introduced. Several kinds of memories are extended on each DSP periphery and the data transmission is achieved by double port RAM. Because of pipeline structure design, the operation rate is very high. With using two DSP, the system rate is improved. The hardware platform has high calculation speed and small size, and it is suitable for the embedded celestial navigation system.
