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

The design is based on an ARM? microprocessor that controls the entire chip. A number 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.
