Device for realizing data exchange between high-speed interfaces

Abstract

The invention provides a device for realizing data exchange between high-speed interfaces, which comprises a camera microprocessor, an external memory interface (EMIF)-Video Port converter and an intelligent analysis microprocessor, wherein the EMIF-Video Port converter is respectively connected with the camera microprocessor and the intelligent analysis microprocessor. The device for realizing data exchange between the high-speed interfaces provided by the invention realizes the high-speed data transmission between the camera microprocessor and the intelligent analysis microprocessor by establishing a high-speed data channel between the camera microprocessor and the intelligent analysis microprocessor.

Description

technical field [0001] The invention relates to the technical field of traffic monitoring, in particular to a device for solving data exchange between high-speed interfaces. Background technique [0002] At present, an intelligent monitoring system usually includes a front-end camera and a back-end intelligent analysis device. The image or video collected by the camera is transmitted to the intelligent analysis device, and the image or video is detected, recognized and behaviorally analyzed by the intelligent analysis device. At present, there are two main data transmission methods between the camera and the intelligent analysis device: one is that the intelligent analysis device directly obtains the original image or video, which has a large amount of data, and communication interfaces such as LAN, USB data line and 1394 data line The number of frames that can be transmitted per second is low, and the intelligent analysis is based on the low frame rate, which greatly reduce...

At present, there are two main data transmission methods between the camera and the intelligent analysis device: one is that the intelligent analysis device directly obtains the original image or video, which has a large amount of data, and communication interfaces such as LAN, USB data line and 1394 data line The number of frames that can be transmitted per second is low, and the intelligent analysis is based on the low frame rate, which greatly reduces the effect of intelligent analysis

Another method is to compress the original image into JPEG, H.264 and other formats, and transmit it to the intelligent analysis device through the communication interface, and the intelligent analysis device decompresses it again. This method has high requirements on the compression device and causes more waste of resources
