System supporting real-time processing inside streaming data piece and design method

Abstract

The invention relates to a system for supporting real-time processing inside a streaming data piece and a design method. The system comprises a streaming data acquisition module, a streaming data transcoding module, a streaming data caching module and a streaming data display module, wherein the streaming data acquisition module utilizes a VHDL to design a streaming data sensing device configuration unit and a streaming data parallel acquisition unit, the streaming data transcoding module utilizes the VHDL to establish a production line and a shifting operation architecture and improve the efficiency of conversion from a YCbCr format to an RGB format, the streaming data caching module utilizes FIFO to establish a two-stage queue cache, solve the problem of data communication between three-stage asynchronous clock domains and further solve the problem of data collision caused by the fact that the streaming data acquisition speed and the transcoding speed are inconsistent, and the streaming data display module utilizes the VHDL to design an HDMI chip configuration unit and enable the streaming data to be displayed on the external display through an HDMI interface. The streaming data processing system integrates acquisition, transcoding, caching and display functions and can improve real-timeliness of streaming data processing, and high integration and miniaturization of the streaming data processing system can be also promoted.

Description

technical field [0001] The present invention belongs to the fields of electronic engineering and computer science. The present invention specifically relates to a system and design method that supports real-time processing of stream data in a slice, and aims to design a stream data processing system that integrates functions such as collection, transcoding, buffering, and display, and can not only improve the efficiency of stream data processing Real-time performance can also promote high integration and miniaturization of streaming data processing systems. Background technique [0002] The advent of the digital age has put forward higher requirements for the streaming data (such as high-definition video streaming) industry. The high-definition video stream real-time display processing system has been widely used in weather forecast, robot vision, medical image, missile precision guidance and other fields. In the field of aerospace, ballistic weapons generally adopt a vari...

Problems solved by technology

However, the most common high-definition video streaming system at present, that is, the mode of PC plus capture card, not only seriously lacks in portability, but also cannot meet the requirements in terms of real-time video stream processing.

Even some video stream processing systems can meet the requirements of portability and real-time performance, but they are not widely used because of the high cost
