VIP (Video Input Processor) Function Description
VIP is a Video Input Process unit which processes incoming data either from Graphic card or Video
Decoder.
With Line Buffers and Decimation logic based on proprietary Smartscaling
TM
–2 algorithm , it can process
input data and then write to frame buffer . Furthermore, it can detect the polarity of input H/V SYNC and
then do the normalization of them and also detect the ODD/EVEN field of the input interlaced data. It can
also measure the pulse width and period of input H/V SYNC for system application purposes.
Video encoder interface is supported for video image input.
MIU (Memory Interface Unit) Functional Description
MIU is a interface unit between external DRAM and this chip. We support 6 kinds of configurations for
SDRAM and SGRAM through POWER_ON Strapped_Input or register defined value.
