7. TCO-9141D(13MHz)
This system uses the 13MHz TCXO, TCO-9141D, Toyocom. AFC control signal form OM6357 controls frequency from
13MHz x-tal. It generates the clock frequency. This clock is connected to OM6357, YMU762 and OM5178.
9.Camera DSP(MV317SA)
Tiger is an Integrated circuit for mobile phone camera.
This structure will allow effectiveness for
large data management and significantly reduces main processor will get burden.
In hence, Tiger will allow the user to be able to display to LCD direct without burdening the main
processor. It also allows to have various kinds of display size on the LCD and snapshot for Jpeg. Digital
effect will also be executed on real time base resulting Tiger as being a video co-processor in the
mobile platform.
Also,an
i80 type processor’ s 16bit parallel interface of Tiger makes it available for the CPU to interchange the data
with Tiger. As the additional 8Mbit is usable except 2Mbit buffer embedded in Tiger, the diverse UI data processing
which is not a
burden to the CPU is available.
JPEG encoder and decoder are baseline ISO/IEC 10918-1
JPEG compliance (DCT-based). JPEG decoder supports YUV444, YUV422, YUV420 and YUV411 format
standard JPEG image.
