Abstract
Method of transferring isochronous data from a source over a clocked channel to a sink. The data is compressed by a compression ratio responsive to a depth of a first variable stack. The compressed data is stored in the first stack and clocked by the channel. Compressed data on the channel is expanded and stored in a second variable stack. The variable stack is clocked to maintain the second variable stack at a constant depth.
Claims1
Method of transferring isochronous data having a data rate from a source over a clocked channel having a traffic rate to a destination comprising the steps of:
- compressing said data by a compression ratio responsive to a depth of a first variable stack;
- storing compressed data in said first variable stack;
- clocking said first variable stack by said channel at said traffic rate;
- expanding compressed data from said channel;
- storing expanded data in a second variable stack;
- and clocking said second variable stack at a clock rate to maintain said second variable stack at a constant depth, said clock rate equal to said data rate.
