Abstract:
1. A data compression system for splitting input DCT (Discrete Cosine Transform) transform data into transformed data halves, the system for use in data storage and data communications, the system comprising, a plurality of communication lines operable to couple a plurality of process units to a buffer, the plurality of process units adapted to implement at least portions of a rotator and a splitter, the rotator for rotating the input DCT transform data into rotated transformed data, and the splitter comprising process units for splitting the rotated transformed data into transformed data halves of odd transformed data and even transformed data, the process units being rotators having the same rotation angle, each of the rotators provides odd transform data and even transform data of the transformed data halves, the transformed data halves being lossless transform data.
