LM9702 Real Time Digital Image Processor

General Description

The LM9702 contains all functions needed to build a VGA digital

still and/or video camera. It incorporates a 16 bit RISC micropro-

cessor, a flexible image processing pipeline, hardware JPEG

compression, and the required periphery modules in a single IC.

This architecture allows a very fast click-to-click time and full res-

olution video without sacrificing image quality or cost; because

the computation extensive operations are processed by circuitry

dedicated to image processing. The highly optimized memory

management provided by the LM9702 keeps the memory cost of

the complete camera to a minimum.

A chip set comprising of the LM9702 and a National VGA CMOS

image sensor complemented by a lens, battery, compact flash,

power management for the battery, and LCD (optional) yields a

complete high performance cost effective digital still and/or video

camera.
