Hi all, I'm doing a project to do 'real time active noise cancellation' on blackfin 533. My second step towards the project (the first step is verification of algorithm in matlab) was to send two correlated low frequency audio signals (which i created from matlab) into blacfin 533, and tried to cancel the signal using LMS algorithm. As the codec for blackfin 533 sampled the audio signal a...

I have a quick question about the video applications in the latest Blackfin SDK. They seem to all be for 533s or 561s. I have a EZKIT-BF537 with the AV daughter-board. I was hoping someone would have an idea what issues I might have porting these, or what I should look for (or even if it's just a stupid idea in the first place). All suggestions most welcome. John
