The subminiature SINS computer system based on DSP and MCU
Jiang Zhi-yong · Applied science and technology · 2008
A sort of SINS computer is designed based on DSP,in which a double CPU structure was adopted involving a DSP and an MCU.The DSP is mainly responsible for data calculation and the MCU responsible for data collection and control of the system.At the same time,CPLD completes decoding and control.The data exchange between the MCU and the DSP was realized through HPI interface of DSP.The block diagram of hardware structure and flow chart of program design were given.The presented method is important for navigation computer's miniaturization and the reduction of cost and volume of the navigation system in military and engineering fields.
