A kind of two-stage DCT coefficient storage method based on pointer suitable for HEVC standard

The invention belongs to high-definition digital video compression coding and decoding technical fields, specially a kind of two-stage DCT coefficient storage method based on pointer suitable for HEVC standard.DCT coefficient is divided into three parts by the present invention：Sign bit, high position data and low data, and the upper section of data bit is incorporated into as high position data, remaining bits incorporate into as low data；Simultaneously using SRAM as the first order in storage hierarchy, for stored symbols position, low data and the high bit pointer that can point at high position data；Using register as the second level in storage hierarchy, for storing the high position data that some need to store；And calculate that high bit pointer is gone forward side by side line index using counter.The present invention reduces hardware costs by the storage strategy of stratification.
