摘要： A memory arrangement method and system for AC/DC prediction in video compression applications based on parallel processing is disclosed. The method and system achieves optimum operating efficiency for data operation and reading based on parallel computing characteristics (Single Instruction Multiple Data (SIMD)) of an operation unit of the system. Additionally, the method transplants a VC-1 video compression system running in an operating system (the Windows operating system, for example) to a system platform using a digital signal processor (DSP) as an operation unit and implements a real-time VC-1 encoder according to parallel computing characteristics of a hardware core of the system platform.
