Abstract
A device is described that includes an encoder/decoder (CODEC) in which functionality is partitioned between a video front end (VFE) and a video back end (VBE). The VFE encapsulates functionality and image processing operations to support a variety of applications, and presents a flexible inter-processor by which an external master device can easily control these operations. The video back end (VBE) operates as an encoder and/or a decoder to generate encoded and/or decoded video sequences. The VFE and VBE may execute within an operating environment provided by a slave device.
