ABSTRACT:
A method of and an apparatus for parallel processing video compression is described herein. A picture is divided into N zones vertically, and Vertical Split Parallelism (VSP) deploys N+1 processes: N M-coding processes for general macroblock coding in N zones and one E-coding process for entropy coding. By dividing a macroblock encoding process into M-coding and E-coding processes, multiple M-coding threads and one E-coding thread are able to progress simultaneously with proper synchronization between threads. Since the workload of M-coding processes is greater than E-coding for each macroblock coding process, two cores are able to be designated to the two M-coding processes. Either of the cores are able to be designated to the E-coding process since the workload of E-coding is light. Therefore, VSP utilizes parallel processing computing power efficiently.
