Abstract

The invention relates to a real-time high-speed multi-DSP distributed processing system which comprises a communication processing circuit used to realize information exchange with a computer, wherein, the communication processing circuit is connected with a data bus; the data bus is connected in parallel with a plurality of DSP digital processors used in data processing; the communication processing circuit is also connected with a data bus arbitration logic circuit used to generate arbitration control signal; moreover, the data bus arbitration logic circuit is connected with each DSP digital processor through a data bus arbitration control lead wire. Compared with the prior art, the invention has the advantages that: 1. the invention combines with the HPI bus technology and the multi-DSP processor parallel processing and real-time transmission technology; 2. based on sharing resources such as a bus, the invention realizes high-efficient coordination of the operation of each DSP through the data bus arbitration logic circuit, thereby remarkably improving the real-time transmission capability of the entire system communication and data information.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a real-time high-speed multi-DSP distributed processing system, which is especially suitable for large-scale high-speed data collection and processing, real-time data analysis, digital image processing, video processing, real-time control and other signal processing fields. Background technique [0002] As a digital signal processor, DSP is used in various fields of signal processing. However, as the requirements for real-time signal processing capabilities are getting higher and higher, the traditional single DSP processor system is limited by the resources of a single DSP processor. High-speed data acquisition and processing and real-time analysis, signal processing and calculation in large quantities cannot meet its requirements. In order to improve the processing capacity, people try to realize by increasing the number of DSP processors. [0003] Existing data processing sys...
