一种可编程异构芯片设计方法应用于视频桥接
A Programmable Heterogeneous Chip Designed for Video Bridging
摘要
Abstract
With the development of intelligent era,more and more devices have cameras and display screens,which are in various video formats with different interfaces.To fill the gaps,video bridging is widely required.The previous solu-tions adopted field programmable gate array(FPGA),graphics processing unit(GPU),and application specific integrated circuits(ASIC).However,it is difficult to meet the requirements of low cost and ultra-low power consumption and miniatur-ization,especially in the field of mobile display.This paper proposes a novel heterogeneous architecture which seamlessly integrates FPGA,microcontrol unit(MCU),ASIC,and memory into a single silicon chip.This chip not only achieves minia-turization,but also has the advantages of low cost and low power consumption;More importantly,this chip can support bridging requirements for different interfaces and video formats.At the same time,this paper provides evaluation methods and solutions for different algorithm applications,and provides a basis for architecture design.The chip has been successful-ly taped out in an industrial 22 nm process.It can support video input formats with a resolution of 3 840×2 160 and a re-fresh rate of 144 Hz,as well as video output formats with a resolution of 1 080×2 340 and a refresh rate of 90 Hz.The ex-perimental results show that,in supporting the similar function,the overall chip size is about 4 mm×4 mm and the total pow-er consumption is about only 200 mW,both of which are less than one tenth of AMD XC7K325T and Zynq Z7035.In other words,for applications in video bridging scenarios,our solution has significant optimization compared to traditional com-mercial FPGAs in terms of cost and power consumption.关键词
