Spaceborne real-time parallel data processing system

Abstract

The invention provides a space-borne real-time parallel data processing system aiming at the characteristics of huge data volume and high real-time processing requirements of the space-borne system. The system mainly consists of a power supply subsystem, a dedicated instruction set processor parallel processing array subsystem, and a data distribution-driven synthesis subsystem to form a three-layer processing platform structure. The data distribution-driven synthesis subsystem is used to complete the preprocessing and processing of input data The result output is located in the middle layer of the entire processing platform; the special-purpose instruction set processor parallel processing array subsystem is located on the top layer of the entire processing platform, and the special-purpose instruction set processor is used to form a parallel processing array to complete the processing of input data; the power supply subsystem The system provides power for the entire system and is located at the bottom of the entire processing platform; the three subsystems are connected through a dedicated bus layer. The invention has the advantage of being able to realize real-time parallel fast processing of massive data on the satellite, and can be used for denoising and compressing distributed images on the satellite.

Description

technical field [0001] The invention belongs to the technical field of data processing, in particular to a parallel data processing system, which is suitable for satellite data processing systems with large data volume and high real-time requirements. Background technique [0002] Satellites play a very important role in national economic construction, disaster reduction and prevention, and military intelligence collection. With the continuous increase of civilian and military needs, the demand for on-board data processing systems is becoming increasingly urgent, and the requirements for on-board computing and processing platforms are also getting higher and higher. Processing raw data on satellites is already an essential task, and on-board processing algorithms are becoming more and more complex and diverse, resulting in higher and higher performance requirements for on-board data processors. [0003] At present, the advanced spaceborne data processing system is developin...

Problems solved by technology

Among them, the implementation method using FPGA has poor versatility and portability, resulting in high system complexity, because one circuit is only suitable for one algorithm

The implementation method of DSP software programming is very flexible, but due to the performance of DSP itself and the serial execution of program instructions, it is difficult to achieve parallel processing and the data processing efficiency is low.
