GENERAL DESCRIPTION
The SAA8112HL is a powerful and versatile 10-bit digital
processor for video cameras. It processes the digitized
sensor data and converts it to a high quality, multi-format
and YUV digital signal. In addition, the SAA8112HL
performs programmable statistical measurements on the
video stream allowing, for instance, a precise
measurement of the exposure or the white balance levels.
An 80C51 microcontroller derivative with five I/O ports,
I
2
C-bus, 512 bytes of RAM and 32 kbytes of program
memory is also embedded in the SAA8112HL.
The microcontroller is used in combination with the Digital
Signal Processing (DSP) measurement capabilities to
provide advanced AE, AWB and AOB. The microcontroller
may also be used to control other devices in the camera,
for example a USB or a 1394 interface.
In the following description of the SAA8112HL, four main
functional blocks are given (see Fig.1):
The DSP block
The DSP ME block
The microcontroller block
The timing, interface and miscellaneous functions block.
