TMS320C5515: how to run the Digital Stethoscope MDK on EVM5515

Part Number: TMS320C5515


I am trying to run the demo application of document called ' Digital Stethoscope Implementation on the TMS320C5515 DSP Medical Development Kit (MDK)' on EVM5515 board. The link of this document is . I have 3 questions:

1,In the document, the FE board is AIC3504. I cannot find any place to buy this board. Please help.

2, this document is very old as it was using CCS3.x. Does the Stethoscope MDK have a newer application note?
