Embedded real-time image processing platform device

Abstract

The invention discloses an embedded real-time image processing platform device comprising an interface module provided with various interfaces for connecting external devices, a control module used for operating an operation system for managing and monitoring, a computing module used for computing data at high speed by utilizing a plurality of DSPs (Digital Signal Processors) and a power management module used for providing a power supply scheme for the whole device. External video stream and / or image data are input from the interface module through an external A / D (Analog / Digital) conversion module under the managing and the scheduling of the control module, and then are transmitted to the computing module to be processed, and result data are stored or output from an output interface of the interface module and displayed, thereby real-time image processing is finished. The embedded real-time image processing platform device has the advantages of high computing efficiency, good interaction, strong real-time, good reliability, flexible structure, good universality and strong expansibility, can be used for the development of conversional interfaces and high-speed computing processing, and can be effectively applied to researching, testing and developing of various methods in the digital image processing field.

Description

technical field [0001] The invention belongs to the field of digital signal processing devices, in particular to an embedded real-time image processing platform device, which can be used for research, testing and development of digital image processing methods under various application backgrounds. Background technique [0002] Embedded systems refer to application-centric, computer technology-based, tailorable software and hardware, and are suitable for special-purpose computer systems that have strict requirements on function, reliability, cost, volume, and power consumption. Embedded technology has developed very rapidly in the past few decades, and more and more image processing problems and real-time control problems can be realized in embedded systems. The reason for the rapid development of embedded systems is not only its small size, but the most important thing is the embedded real-time operating system that came into being with embedded systems. The operating syste...
