Copy Y-data

Started by shan-e-ahmed-raza June 7, 2008
Hi
I want to extract only y data from sframe0 (which is in UYVY 4:2:2
format) in Video inout example and save it.

Please help me in this regard.

Thankyou.
HI,

You can do a couple of things. If you already received the data into
sframe, as per example, you can setup a memory DMA to move just the Y data
from sframe (data size is 2 bytes but the modify value is 4 bytes). Just
make sure the initial start address points to the first Y value.

Alternatively, you could go to the PPI control register and set it to
receive every other (ie skip every even or odd) value.

Hope this helps.

Cheers,

George Kadziolka
