PARALLEL ENCODING/DECODING OF DCT COMPRESSION/DECOMPRESSION ALGORITHMS. |
摘要 |
Encoding and decoding speed in using DCT and IDCT algorithms is enhanced by parallel operation of coding and decoding devices. A frame of image data can be vertically sliced with each slice operated on by a dedicated encoding device and with the encoded slice data concatenated to form the encoded frame of data. Decoding speed is increased by using a plurality of decoding devices in parallel with each decoder having a Huffman decoder and a coefficient dequantizer through which all coded data flows. Only assigned blocks of data are operated on by the IDCT unit in each decoder. Each decoder device can have a plurality of IDCT units for operating on assigned blocks of data. |
