Video data processing and processor arrangements

Abstract

Consistent with one aspect, a circuit arrangement performs a variety of operations for tasks relating to motion and includes one or more ALU components. One such circuit arrangement is adapted to provide a picture phone that includes: a telephone transceiver; a camera; a display; a digital signal processor (DSP), including a multiplier unit, adapted to perform image data (de)compression; and a reduced instruction set computing (RISC) processor for routing data among the camera, the display, the DSP, and the telephone transceiver. Further, a memory is used to store (de)compression algorithm code executed by the DSP and data routing control code executed by the RISC processor
