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.
