Hi,i am using Bf561 EZkit to run my algorithem for this i want to
access the incoming frames from real time video,any one please help me
how can i access frames i am sing Vidioinout example also i want to
transmitt these frames to UART,specially i request miracle_skism kindly
help me if u can.UART project is running stand alone
thanks
Video in out on BF561

Hello
Is impossible to transmitt real time video via Uart, the uart has a maximum
speed of 115200 bps.
You can transmit via Uart some frames.
What do you need exactly?

Hi
I want to access the incoming frames in video in/out example of BF-561.
and then implement my algorithm on the frames, I want help and any kind of
information.

Hello,
In the example your image is stored in L3 memory. You can process your image
in the interrupt service. Pixels are memory mapped. You just need to acces
memory to process pixels.
The easiest way is to work DMA in stop mode.
However if you need better performance you should process your image from L1
line by line in autobuffer mode.
L1 is an internal memory that can be accesed at core clock frequency.
There are also some alu functions that allow you to process 4 pixels at the
same time. byteop1p,...

Hello
You can use the Image viewer of VisualDSP
However the image in memory that you have with the example have blanking
fields, and is in YCbCR 4.2.2. Look attached Image is from the HWR manual
Analog
In memory you have 2 fields even and odd according with itu r656.
Blanking Cb Y Cr Cb Y Cr......///1716 per line
Blanking Cb Y Cr Cb Y Cr......///1716 per line
.
.
.
Blanking
then the other field
use this configuration to see one part of the frame>
StartAddres> 0xc400 or you select Sframe0
Linewidth. 1716
Stride 1
8 bits
Height// 200 ...Just to see a portion
However according with your application you would like to filter blanking.
The PPI can done this work, just setting some bits in PPICONTROL register.
Sometimes is usefull to also filter crominances. It is also done by the PPI.
