| Abstract: | 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. |
