8.3.4 Audio Processing

8.3.4.1 PCM512x Audio Processing

8.3.4.1.1

Overview

The PCM512x supports a fixed audio processing flow with programmable coefficients. (Program 5 - Fixed Audio

Processing Flow (Program 5) of this data sheet). Details can be found below.

NOTE

At higher sampling frequencies, fewer instruction cycles are available. (For example, 512

instructions can be done in a 96-kHz frame.)

The audio processing chain can run up to 1024 instructions on every audio sample at a 48-kHz sample rate.

8.3.4.1.2

Software

Software development for the PCM512x is supported through TI's comprehensive PurePath Studio Development

Environment; a powerful, easy-to-use tool designed specifically to simplify software development on the

PCM512x audio platform. The Graphical Development Environment consists of a library of common audio

functions that can be dragged-and-dropped into an audio signal flow and graphically connected together. The

DSP code can then be assembled from the graphical signal flow with the click of a mouse.

Please visit the PCM512x product folder on www.ti.com to learn more about PurePath Studio and the latest

status on available, ready-to-use DSP algorithms.
