Hi There,
Current we are designing a system using AM1808 and interfacing CMOS Image sensor with VPIF - CMOS Image sensor is capable of giving output in following format
1. 8bit bayer RAW pattern
2. 10bit RAW Bayer
3. 8 bit YVU with external HS / VS and Clock
4. 8 bit BT.656 - Embedded HS/vS with clock
Now based on , “Table 3. Receive Pin Multiplexing Control” on page 14 of document “AM17x/AM18x ARM Microprocessor Video Port Interface (VPIF)”. The TI literature for this document is SPRUFW7. we have concluded following things.
VPIF Supports 8bit, 10 bit and 12 bit Raw capture Mode – we need to connect the RAW video
a. In case of 8 bit – From VP_DIN[0:7] DIN7 as MSB and DIN0 as LSB
b. In case of 10 bit – From VP_DIN[0:9] DIN9 as MSB and DIN0 as LSB
c. In case of 12 bit– From VP_DIN[0:11] DIN11 as MSB and DIN0 as LSB
In Case of BT.656 interface we need to connect 8 bit Data signal on VP_DIN[0:7] - DIN7 as MSB and DIN0 as LSB
Now the assumption here made is regarding MSB and LSB, We have assumed that ,
VPIF_D0 is LSB and VPIF_D12 is MSB [Its not specified in AM1808 data sheet or VPIF user guide]
Can any body validate above understanding and assumption we made ??
