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.
