[Dspforum] IIR lab question.

[Pablo Pombo]

Do we need to implement ping-pong buffers in input and output or single buffers are acceptable?

Subject: [Dspforum] Today's Class

Just wanted to let everyone know our schedule for class today so that they can plan accordingly.

We have no assignments due this week, so no solutions will be discussed, and we will have no quiz.  There will be a quiz next week which should cover what you did for the STFT lab.

Most of the class will be devoted to working on the EDMA lab, which I understand is a little bit strange to debug. We will briefly discuss the new assignment (IIR filter lab), but there will not be an extended lecture on IIR filters.  


Class Schedule:

1. 10 minutes of examples of practical IIR filter performance
2. Distribute/Discuss IIR Lab (if you don't come to class, don't download until classtime, I'm modifying this)
3. Off to lab to work on codec interface with EDMA


I really want everyone to have a robust EDMA solution for the codec interface, because we will be using it for most future labs.  Using EDMA and doing block processing (rather than sample by sample) is clearly a preferable method that I want everyone to be quite comfortable with.


Summary :  If you are very comfortable with the EDMA lab, and you are essentially finished, class tonight is probably something you could miss.  I encourage anyone who is not comfortable to make sure that they attend tonight so that we can devote some lab-time to helping you out.


We'll still meet in the classroom first.

Doug
