ABSTRACT:
An improved system and method for the transference of data with minimal delay and loss is disclosed. Primarily useful in maintaining the flow of an isochronous data stream, the present invention minimizes delay through the use of a shared buffer for both the data source and destination and without reliance upon an interrupt to transfer data. The present invention minimizes data loss through the use of a double buffer, the size of which is adjusted to accommodate interrupt latency without increasing transference delay.
