Description

technical field [0001] The invention relates to the technical field of combined navigation and image processing, in particular to a high-speed and large-data-volume information processing system. Background technique [0002] In the technical fields of integrated navigation and image processing, a large amount of navigation data and images require higher and higher real-time signal processing capabilities, and the complexity of data processing is increasing. Integrated navigation requires automatic matching methods, and the requirements are quite high. High precision and high real-time performance all require more in-depth research on image matching algorithms. At the same time, its application environment has strict restrictions on system power consumption and size. Due to the limitation of a single DSP processor resource, it cannot meet its requirements in terms of high-speed data acquisition and processing, real-time analysis, and large-scale signal processing and calcula...

Problems solved by technology

The implementation of signal processing based on single-core DSP is difficult to adapt to the new demand for real-time processing of large amounts of calculations. The traditional DSP interconnection technology is to connect multiple single-core DSPs with high-speed interfaces. Its real-time data transmission capability and main control DSP processing The resource overhead of the processor will become the bottleneck of the system with the increase in the number of serially processed DSP processors, thereby limiting the expansion of the system and the improvement of actual processing performance, which cannot fully meet the needs of signals with large amounts of data and strong real-time performance. Processing requirements in the processing domain, while such a system architecture presents power and size issues
