描述 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 displayIt 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 cameraThe 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.
