Abstract

McASP is TI’s Multichannel Audio Serial Port. The McASP functions as a general-purpose audio serial port optimized for the needs of multichannel, multi-zone audio applications.

It has been designed into many audio products, such as Audio/Video Receivers, sound bars, automotive amplifiers, and infotainment systems.

This application report is intended for engineers who are new to designing audio systems featuring McASP using Linux as the HLOS (High Level Operating System).
