Method for forecasting memory resource allocation of security protection video hard coding chip

Abstract

The invention discloses a method for forecasting memory resource allocation of a security protection video hard coding chip. System use memory is computed by a special computing method, in a hardware environment, errors can be corrected in such a manner that memory resources are forecast by software when a memory resource allocation computing unit module in the video hard coding chip has computation errors, a correct coding video frame can be outputted, and a series of problems caused by memory allocation errors are solved.

Description

technical field [0001] The invention discloses a method for allocating memory resources under the condition of a security video hard-coded chip, especially for a situation where the video hard-coded chip hardware computing unit makes an error in predicting the memory resource, which leads to a decrease in image quality or an error in the encoding process. A predictive method for memory resource allocation of security video hard-coded chips. Background technique [0002] Video hard-coded chip refers to the chip that does not depend on the main control CPU, and completes the audio and video decoding work independently through a dedicated SOC chip (System on Chip), such as: H.264\MPEG-4 video compression of DVR and IPC equipment in the security field etc., are basically "hard-coded" dedicated SOC chips. At present, most of the video encoding chips used in the security industry adopt a hard-coded solution. This solution generally adopts the integration of the hard-coded SOC chi...

Problems solved by technology

[0008] 1. Due to the late start of this technology, the support and flexibility of embedded software cannot be compared with soft coding;

[0009] 2. Faced with the chaotic video encoding and packaging formats on the market, hard decoding cannot be fully compatible;

[0010] 3. Soft coding has a large number of image output compensation and image quality enhancement technologies, while hard coding is still insufficient in this regard;

Once the hard-coded chip is finalized, the encoding format it supports and the computing unit modules related to hardware system resource allocation cannot be adjusted, especially the computing unit modules for hardware system resource allocation.

If the system resources obtained by the calculation are wrong, it will lead to coding errors or exceptions; system resource allocation mainly involves the allocation of memory resources. As a result, the image quality of video frames in this encoding format is degraded or errors occur. For example, when the encoded output video frames are decoded and played, video color errors, black screens, and blurred screens occur. especially important
