Control signal flow
The single-board is directly controlled by the CPU of the main control unit, which sends configuration and query commands to each unit in the single-board through the control bus; the command responses, alarms, performance and other events reported by each unit are also reported to the CPU through the control bus.
The logic control unit is responsible for decoding the address read/write signals from the CPU of the main control board and loading the FPGA software.
Clock Unit
The clock unit receives the system clock from the backplane control bus and provides clock signals for other units of the single board.
