Embodiment Construction
[0022] The target machine of this embodiment adopts the SPARC V8 processor as the CPU, and the host machine adopts the PC machine, and uploads the memory data or program of the target machine through 1553B bus, serial communication bus (UART), CAN, SPI or SPACEWIRE bus Load and download back to control the program execution flow of the target machine. Commands, data, and status responses between the host and target are all transmitted in the form of protocol packets. Normally, the PC always sends a command packet to the target machine first, and the target machine sends back the corresponding status response packet to the PC according to the protocol after receiving the command packet correctly. figure 2 It is a brief block diagram of protocol transmission.
[0023] Choosing which bus to use to establish the communication between the host and the target is transparent to the target, and this kind of bus can be changed as long as it meets the needs of the interface. The specific...
