Description
Real Time Digital Image Processor
Manufacturer
National Semiconductor Corporation
Datasheet
LM9704 Real Time Digital Image Processor
General Description
The LM9704 contains all functions needed to build an SXGA or
VGA digital still and video camera. It incorporates a 16 bit RISC
microprocessor, a flexible image processing pipeline, hardware
JPEG compression, and the required peripheral modules in a
single IC. This architecture allows a very fast click-to-click time
and full resolution 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 LM9704 keeps the mem-
ory cost of the complete camera to a minimum.
A chip set comprising of the LM9704 and a National SXGA or
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 digi-
tal still and/or video camera.
