Design And Verification Of SOC For High-Speed Media Transmission And Processing

With the increasing standard of living,video streaming is increasingly being used in everyday entertainment.Video can provide a more direct visual stimulation than text or pictures,but at the same time the data transmission rate requirements will become higher and higher.In some specific cases,there is a long physical distance between the sender and receiver of video media,when the ordinary media transmission protocols in daily use scenarios will not be compatible with the two needs of high speed and long transmission distance.So we need to set a high-speed media transmission protocol to meet the long-distance transmission requirements.At present,some foreign chip manufacturers have started to develop high-speed media transmission transceiver chips in this direction,but the transmission protocols they use are all private standards,which are not compatible with each other;and there is no suitable protocol standard to meet the design requirements of long-distance high-speed media transmission transceiver chips in China.This thesis mainlyproposes a high-speed media transmission protocol that can meet the transceiver function of mediumor long-distance high-speed media transmission in most scenarios,and designs a SoC system that can integrate the protocol interface according to the application requirements,integrating the video processing function with the transceiver function of medium-and long-distance high-speed media transmission,so that it can meet a wider range of application scenarios.This thesis firstly proposes a more unified protocol specification based on the demand of medium-and long-distance high-speed media transmission,introduces the application scenarios of the protocol,briefly introduces the physical layer based on the transmission protocol stack,and highlights the packet format and interaction flow of various service types in the media encapsulation layer;then designs the bus matrix of the SoC system based on the AMBA bus,and completes the system architecture design such as address mapping.Then the design description of the register level(RTL)of the video media encapsulation and unpackaging and PSK information security authentication process is completed based on the proposed protocol specification,and the functional simulation of the design results is performed;meanwhile,the integration process of the system is introduced with the SDIO interface IP as an example,and the functional simulation verification of the SDIO interface module is completed.Finally,the FPGA prototype verification platform is built according to the SoC requirements,and the ASIC design transformation and integrated wiring process are introduced with the SDIO interface as an example,and the on-board verification of the system SDIO interface function and video image transmission function is completed in the FPGA verification platform.
