[0063] Step 1: Set up shared memory inside the on-board computer system. This shared memory is 8K×16bit in total, and can be continuously expanded according to the increase of interactive information. Divide this shared memory into three equal physical address spaces, each computer can read all the memory space, but can only rewrite the physical address space corresponding to this computer;
[0064] Step 2: The computer uses the underlying instruction set to access the memory address through the IO interface between the CPU chip and the shared memory to obtain the interaction information provided by other computers and the interaction information written into the machine. The CPU accesses 700 IOs every 1ms, each IO is 16 bits, and the code rate is about 11.4Mbps. This rate far exceeds the 2Mbps of the 1553B bus and the 114.2Kbps of the serial port 422, which can meet the requirements of the Mars exploration process and the rate of information exchange between the control softw...
