Abstract
A method for sharing a buffer among multiple context engines, is provided. The method includes loading a memory element with a first data sequence. The method further includes loading a corresponding first context information to one of the multiple context engines. Subsequently, a direct memory access engine is loaded with the first data sequence dictated by the first context information. Then, the first data sequence is processed. While the first data sequence is being processed, the method includes loading the context engine with a next context information for a next data sequence contemporaneously with the processing of the first data sequence.
