Video Stream and Multiple Buffering

Question asked by Robert83 on Nov 19, 2010

Hello,

 

i am working with the ADSP-BF561 EZ-Kit and the example code for a video stream without processing. For the buffering of the video-frames

a buffer chain located in the external SDRAM is used. Is it correct that when a new video-frame is written into buffer[x]

the buffe[x-1]is read out simultaneously? But how can this work, because i think that there can be only one access (read or write) to SDRAM at one point in time?

 

Thanks for help

 

Robert
