Quad-core image processor

摘要

A quad-core processor for use in a hand-held device with a CMOS image sensor. The quad-core processor has an image sensor interface for receiving data from the CMOS image sensor and four processing units interconnected with each other for parallel processing of data from the image sensor interface. The four processing units and the image sensor interface are integrated onto a single chip.
