Description
The AT76C113 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
AT76C113 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, MPEG-1 coding/decoding, DMA
access to SDRAM, and video encoding. All these computationally-intensive functions
are implemented in hardware which can be programmed according to user specifica-
tions, thus allowing ARM to be free for other user-defined functions.
Part Versions
The AT76C113 device comes in six versions, each with slightly different features. These
are summarized in Table 1. In the rest of this document, the AT76C113-HU part is
discussed.
