摘要
Abstract
In order to update the CPLD allocation software in embedded navigation computer system, a update scheme of CPLD allocation software update based on DSP applying serial port isproposed. The file that contains the information of CPLD configuration is sent to navigation computer system by UART port from PC. The JTAG time sequence logic of CPLD is simulated through I/O port of DSP. The CPLD configuration information file received by the serial port is immigrated into its internal logic to achieve CPLD software update. For the achievement of the above method, some key problems existing ing hardware and software are analyzed and solved. The method for updating CPLD software was implemented and applied in actual navigation computer system.关键词
