Hi,
I am using BF561 for my video application.
I've used SDRAM to store the input frame,and used MDMA to transfer the
data from SDRAM to L1 memory.
I can transfer only 5 lines at a time,
But my application needs the entire frame at one strech.
where can i find the driver files to do the frame processing

Hi Manimekalai,
You can modify your algorithm to work with smaller chunks of data and use
MDMA to bring the data into L1 in blocks. Alternatively, you can use data
cache and work with the data in SDRAM as one block. Many image processing
tasks (eg compression, filtering) can be broken down to work with smaller
blocks of data. What type of frame processing are you performing?
Best regards,
George

Hi,
I am using the VIDEO INOUT code found in Blackfin Example files.
But with that code i can only get the frame and can display with one
frame delay.
In order to process the frame, i used MDMA to transfer the data from
SDRAM to L1 memory.
But here comes the problem.
I need the entire frame into L1 memory. atleast half of the frame.
but i can transfer only a small block of data and not the entire frame.
I suppose i can access the SDRAM directly.
but i dont want to do the same as it delays the speed.
So i prefer transferring the data to L1 memory and do the process.
Is there any driver files to access the entire frame.
Else it it possible to do with VDK.
If yes, kindly suggest me.
regards,
manimekalai

Re: [adsp] frame processing in BF561
Hello
A good option is that you store your image directly in L1. You put the L1
as target of the DMA controller when it get the image from the PPI.
However you can not store all the image in L1, but you can store one line
of the image and generate and interrupt. Process your image by lines.
Bye.

Re: [adsp] frame processing in BF561
Hello,
for the frame processing, First u have to disable DMA
after getting one frame at the ISR.
Then in main function initialize the MDAM and transfer
whole frame to other test_frame buffer. fro that no need
any driver file.
