Abstract

The invention provides a main control device. The main control device comprises a power port, a dual-port RAM module, a CPU module and a communication interface module, wherein the power port is connected with the CPU module and the communication interface module; the dual-port RAM module is connected between the CPU module and the communication interface module and is used for receiving and storing control information sent by the CPU module and detection information sent by the communication interface module; the CPU module is used for reading the detection information stored in the dual-port RAM module, generating control information according to the detection information and sending the control information to the dual-port RAM module; the communication interface module is used for sending the detection information to the dual-port RAM module and reading the control information stored in the dual-port RAM module. According to the main control device, information transmission between the CPU module and the communication interface module is achieved through the dual-port RAM module, communication rate is improved effectively, and then the performance of the main control device is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a master control device. Background technique [0002] In a multi-processor (hereinafter referred to as CPU) system, for example, in a master control device, data exchange and acquisition are important components. The device requires a very high communication rate for data exchange, usually the average rate is about 10K, and sometimes even needs to reach more than 100K. [0003] In the existing master control device, its data exchange and acquisition are usually based on the bus. figure 1 It is the system structure diagram of the existing main control device, such as figure 1 As shown, the CPU board and the communication interface board realize interaction through the data bus on the backplane, and the CPU board and the communication interface board are powered by an independent power supply board. [0004] However, because the communication rate of the data bus is relatively...
