D201376 Distributed processing (distibuted processing) and Parallel processing (Parallel processing) Two different architectures to improve the speed of parallel processing. Distributed processor is a computer system that connects multiple computers in different locations, or with different functions, or with different data through a communication network to coordinate large-scale information processing tasks under the unified management control of the control system.
D201376 distributed processing and Parallel processing Two different architectures are used to improve the speed of parallel processing. Parallel processing is a computer system that uses multiple functional components or multiple processors to work simultaneously to improve the performance or reliability of the system, which at least includes parallelism at the instruction level or above.
D201376 distributed processor is a computer system that connects multiple computers in different locations, or with different functions, or with different data through a communication network and coordinates large-scale information processing tasks under the unified management control of the control system.
For complex high-performance automation systems, such as automatic steelmaking systems, automatic steel rolling systems, high-speed and high-precision CNC device systems, etc., for information processing and control systems requiring high-speed real-time response, such as aerospace communication systems, automatic information processing and control systems of modern civil aviation aircraft, Industrial robot system, which is usually composed of a single microprocessor, can not meet the requirements of the whole information and control system. The computer system composed of multi-microprocessors with relatively dispersed functions can meet the overall requirements of the above system well.
D201376 system designers usually divide the function of the whole system into a thousand relatively independent sub-systems (or sub-modules),
so that each processor in the multiprocessor system corresponds to its sub-system and undertakes the information processing task of the predetermined functional unit of its sub-system, and can also appropriately share the task assigned by some system control functional units. When the whole system is running, each processor subsystem can carry out the information transmission control and processing in parallel and independently. In this way, the integrated real-time response ability of the total system is improved, the throughput and speed of data processing are increased, and its reliability and overall function are also strengthened.
