Method for joint development of video algorithm and hardware implementation

Abstract

The invention discloses a method for joint development of video algorithm and hardware implementation. The method comprises the following steps of: synchronously performing the video algorithm development and the hardware implementation in two principal lines, in the video algorithm development process, estimating objective and subjective vision performance of the video algorithm, simultaneously, performing hardware architecture design for the video algorithm, detecting whether the video algorithm meets a hardware constraint, once the hardware architecture is out of the implementability range of the hardware resource, simultaneously performing the joint optimization of a video algorithm level and a hardware architecture level. The invention further provides corresponding optimization strategies, and provides a development platform matched with a development process, in each link of the development process, the resource of the development platform provides efficient and accurate support so as to ensure that the development of a video processing chip can be finished correctly and quickly. The method can be used for quick development of the video processing chip from the algorithm development to the chip front end design.

Description

technical field [0001] The invention relates to the technical field of chip design for digital video processing, in particular to a method for joint development of video algorithms and hardware, which is applied to the design of high-performance processing chips for video processing such as digital high-definition televisions, set-top boxes, and video surveillance. Background technique [0002] Digital image and video processing technology is widely used in many fields, such as digital TV, video surveillance, medical imaging, industrial inspection and consumer electronics. At present, processing algorithms are usually completed by software. With the development of deep submicron technology and large-scale integrated circuit technology, multimedia real-time hardware processing has become a new development trend. [0003] In the current field of digital high-definition TV in China, most electronic companies adopt two research and development models. One model directly purchase...

Problems solved by technology

This process has two disadvantages. From the perspective of algorithm development, it is likely that the developed algorithm is not feasible in hardware, or the resulting hardware scale is huge, exceeding the constraints of the data bandwidth or scale of the chip; from the chip design. Look, if the algorithm is not changed after delivery, and the optimization effect is limited only by optimizing the hardware structure, it is necessary to formulate a more efficient development process for the joint development of video algorithms and hardware implementation.
