Abstract: A whole I frame AVS real-time video encoder is designed and implemented on FPGA platform in this paper. The system uses the structure of the flow calculation, coupled with a dual-port RAM memory between/among the various functional modules. Reusable design and pipeline design are used to optimize various encoding module and to ensure the efficient operation of the pipeline. Through the simulation of ISE software and the verification of Xilinx Vritex-4 pro platform, it can be seen that the highest working frequency can be up to 110 MHz, meeting the requirements of the whole I frame real- time encoding of AVS in CIF resolution.


Keywords: AVS, Encoder, FPGA.
