Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a signal processing board for processing data in an electronic control system. Background technique [0002] In railway electrical control systems and other industrial control systems, especially in some high-performance real-time control systems, it is necessary to perform complex calculations on large amounts of data, fast calculations on control systems, fast management of peripherals, and external Real-time management of communications, support for operating systems, etc. At present, the commonly used processor cards generally use the CPU architecture. In order to meet the requirements of multitasking, the CPU needs to have a relatively high main frequency. The design of the board is difficult, the chip generates serious heat, and the reliability of the system operation is poor. At the same time, when the single-CPU framework runs the operating system, it cannot t...
