Title: MULTI-TASK MASTER CONTROL SYSTEM FOR REMOTE SENSING SATELLITE IMAGE PROCESSING LOAD
Abstract:
Disclosed is a multi-task master control system for a remote sensing satellite image processing load, the system using a "CPU+2FPGA" architecture, wherein an embedded real-time operating system is transplanted into a CPU to serve as a master control management module for completing state monitoring and management and task scheduling of a remote sensing satellite image processing load, having sufficient flexibility, security and stability; and an FPGA is used for integration and distribution of communication information, may compensate for the defect of the CPU having different interrupt priority levels and limited interrupt vector tables when faced with a plurality time sequence interfaces, and is also used for image preprocessing, able to satisfy the requirements of real-time low delay for a larger amount of data. The system structure design of the present invention can effectively achieve a master control management function, can also satisfy a high parallel processing requirement and a complex floating point number operation requirement for an image, and satisfy the requirements for security, reliability and high flexibility of the system.
