Abstract

The invention discloses a multi-processor parallel processing system for digital signals, which is mainly used for infrared real-time signal processing systems, such as infrared detection systems andthe like. The technical scheme of the invention is shown in a figure 1, and comprises the following aspects of: 1, realizing the communication between a multi-processor platform and an upper host through a PCI bridge and an FPGA; 2, realizing a link port communication module inside the FPGA so as to realize the high-speed communication between the FPGA and a DSP; and 3, realizing a message communication interface needed by the cascade connection of a plurality of multi-processor system boards through the FPGA. The multi-processor parallel processing system has the advantages that the system isprovided with parallel multi-processor inside subsystem boards, and supports that the plurality of multi-processor system boards can form a stronger multi-processor platform through board interconnection.

Description

technical field [0001] The invention relates to computer system structure and parallel processing technology, specifically refers to a multi-processor parallel processing system for digital signals, which is mainly used for processing infrared real-time digital signals of an infrared detection system. Background technique [0002] An infrared detection system is usually composed of two parts: an infrared detector and an infrared signal processing platform. The infrared signal processing platform usually has to complete two main tasks: one is to process the image signal sent by the detector, detect the target with specific requirements from the complex background, and give the target information or further process it; two. Yes, the infrared signal processing platform is required to be able to accept the monitoring of the upper host, and transmit infrared images and detection and tracking results to the upper host, thus forming a complete system. [0003] In the design and de...

Problems solved by technology

[0005] The current multiprocessor platform has the following characteristics: the one is that for the communication path between the multiprocessors, the first-in-first-out memory (FIFO) is mainly used, the transmission speed is slow, and the external bus resources of the multiprocessor are occupied; , for the host computer interface, most of them are still based on low-speed bus, there is no large-capacity cache, there are problems of slow transmission speed, discontinuous intra-frame transmission, and occupation of external resources of multi-processors

Third, in terms of the scalability of the multi-processing platform, due to the use of first-in-first-out memory (FIFO), the connection is complicated and the scalability is poor.
