Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] refer to figure 1 , the spaceborne real-time parallel data processing system of the present invention is composed of a power supply subsystem, a dedicated instruction set processor parallel processing array subsystem and a data distribution drive synthesis subsystem to form a three-layer general processing platform structure. in:

[0024] The power supply subsystem provides power for the entire system, which is composed of DC-DC modules and their corresponding filter circuits, and is located at the bottom of the entire platform;

[0025] As the interface between the system and the external system, the data distribution-driven synthesis subsystem mainly completes the input preprocessing of data and the output of processing results, and acts as a "bridge" between the external processing signal and the parallel processing array inside the 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...
