AT76C110

1475AS–IMAGE–06/02

Description

The AT76C110 is a highly integrated solution for digital cameras. It combines a number

of functions that are required in implementing digital cameras:

•

Image data acquisition and capturing from either CCD or CMOS imagers

•

Image display

•

Image processing and image storing

•

Overall camera management

•

Control of general-purpose I/O functions

•

Data communication

•

Control of user functions

•

On-screen display

It also provides a large number of interfaces that allow camera manufacturers to directly

access a variety of devices that may be present in a digital camera.

•

Communication with PCs

•

Communication with Flash cards

•

Serial communication ports for controlling other devices in the camera

of hardware resources, controlled by ARM, perform digital camera functions such as

image DSP processing, JPEG coding/decoding, DMA access to SDRAM and video

encoding. All these computation-intensive functions are implemented in hardware which

can be programmed according to user specifications, thus allowing ARM to be free for

other user-defined functions.
