PORTABLE HANDHELD DEVICE WITH MULTI-CORE IMAGE PROCESSOR

摘要

A portable handheld device includes an image sensor for capturing an image; and a one-chip microcontroller having integrated therein a CPU for processing a script language and a multi-core processor for processing an image captured by the image sensor. The multi-core processor includes therein multiple processing units connected in parallel by a common crossbar switch. Each processing unit includes an arithmetic and logic unit (ALU), each ALU defining therein two internal crossbar switches for internal data transfer within one processing unit.
