Universal development platform with audio and video functions for embedded measuring and controlling equipment

Abstract

The invention relates to a universal development platform with audio and video functions for embedded measuring and controlling equipment. The universal development platform comprises a bottom plate and a core unit. The core unit comprises a microprocessor and a memory, the dominant frequency of the microprocessor is 1GHZ, 32 / 32KB data / instructions are stored in a first-level cache, 512KB data / instructions are stored in a second-level cache, the operating rate of the microprocessor is 2 hundred million instruction sets per second, various functional modules are embedded in the microprocessor and include an audio and video processing module, a peripheral interface module, a video display module and a network functional module, and the peripheral interface module is connected with peripheral interfaces by 200 pins which are arranged in four rows. The universal development platform for the embedded measuring and controlling equipment has the advantages that the audio and video functional module and the various peripheral interfaces are added into the universal development platform, so that the universal development platform for the embedded measuring and controlling equipment comprises multiple functional modules and abundant interfaces, the development efficiency is improved, development risks and the research and development cost are reduced, and the research and development time is shortened.

Description

Technical field [0001] The invention relates to a development platform for embedded measurement and control equipment, in particular to a general development platform for embedded measurement and control equipment with audio and video functions. Background technique [0002] In the current monitoring system, in addition to the demand for traditional analog and digital acquisition, the demand for sound and video image acquisition, recording, and remote transmission has been increased. The traditional equipment is analog and digital monitoring equipment, video surveillance, and remote The communication equipment is separated, which increases the cost and difficulty of integration of various equipment, and also reduces the reliability and maintainability of equipment operation. [0003] The computing and processing functions of the main control unit of the existing embedded measurement and control equipment platform are not powerful enough, the peripheral interfaces provided are not r...

AI Technical Summary

Problems solved by technology

[0003] The computing and processing functions of the main control unit of the existing embedded measurement and control equipment platform are not powerful enough, the peripheral interfaces provided are not rich enough, and the expansion function modules are single, which makes developers who use this platform have to use some standard generalized functions. Re-development and debugging reduce development efficiency, increase development risk and R&D time, which will inevitably increase R&D costs. However, the biggest defect is that the processor of the existing measurement and control platform does not have audio and video processing functions, because audio and video processing consumes The CPU resources are huge, and ordinary ARM processors are simply not competent, and audio and video are difficult to expand
