Overview

The IPB-AAC-LC-ME-14 is an IP core for encoding up to 14 stereo audio streams in real-time, in one of the following configurations: 14 stereo channels or 12 stereo channels and a 5.1 channel.
The IPB-AAC-LC-ME-14 software requires an audio engine platform named IPB-PLAT-71, which includes 7 processors and one accelerator.
The encoder can be configured, run and monitored by means of a configuration, control, and status register file accessed by APB or SPI.
