摘要
介绍了在光纤陀螺捷联惯导系统中,以DSP为核心的导航计算机系统软件设计,由于TMSVC33 DSP片上只有RAM,无法对程序进行掉电存储,在此,介绍了系统在上电时,存储在片外FLASH的程序引导到DSP上的方法,并对DSP程序进行分析,这里给出程序流程图.该程序通过测试并在实际中得到应用.
The hardware design of navigation computer system with DSP as core is introduced in FOG strapdown inertial navigation system. With only RAM on TMSVC33 DSP chip , the program cannot be saved when power is off. Hence, a way is presented whereby the pregram saved on FLASH outside DSP is rebooted to DSP and DSP program is analysed. The flow chart of program is provided. This program have passed the test and is used in practice at present.
