AT76C110中文资料High-Performance Digital Camera Processor数据手册Microchip规格书

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.
