Abstract

The invention relates to a loading device for centralized storage of satellite-borne multiprocessor software, a software loading method and a software updating method. The loading device comprises a bus, a control module and n processing modules, wherein the bus is connected with the control module and the n processing modules and is used for completing data exchange between the control module and the processing modules; the processing modules are used for completing processing of satellite-borne data; the processing modules do not comprise memories which are used for storing loading programs; the control module is used for completing scheduling and storage of loading software of the processing modules; and the loading software of the processing module is stored in a memory of the control module. According to the device and the methods provided by the invention, the costs of components and parts can be greatly saved, the layout spaces of printed boards can be saved, the power consumption of products can be decreased, the weights of the products can be lightened, and convenience is brought to the updating and maintenance of software.

Description

technical field [0001] The invention relates to the technical field of loading, in particular to a device for centralized storage and loading of software of an on-board multiprocessor, a loading method and a software updating method. Background technique [0002] At present, most of the electronic systems of space vehicles use DSP (Digital Signal Processor) and FPGA (Field-Programmable Gate Array) as the core information processing modules. The functions and performance of the electronic system largely rely on DSP and FPGA software to achieve. In order to improve the processing capability, the parallel processing architecture of multi-channel and multi-processing modules is an inevitable trend and development direction. [0003] Conventional on-board processing module software configuration, such as figure 1 As shown, the processing module includes DSP, FPGA, configuration memory and power supply. The common way to load DSP and FPGA software is to place PROM (Programmable R...
