Overview

The AAC-LC and HE-AAC Audio Encoder (CWda72) is an audio IP core for encoding up to 6 audio channels in real-time.

This core contains the AAC-LC/HE-AAC v1 encoder software and the Coreworks processor based hardware audio engine platform (CWda3111).

The software is compiled into an image file (.bin) which can be automatically boot-loaded through one of the control interfaces (parallel AMBA APB or serial SPI) and run on the audio engine platform with simple parameters setting.

The program can be configured, controlled and monitored by means of a configuration, control, and status register file, accessed by the control interfaces.

The audio input and output interfaces uses a native parallel interface. Other standard audio interfaces, such as I2S/TDM and SPDIF are also available.

The interface to the external memory can be one of the following: AMBA AXI (for ASICs or Xilinx FPGAs), Avalon (for Altera FPGAs) or MIG (for Xilinx FPGAs).

The CWda3111 platform is an instance of the generic CWdaXYZ Audio Engine Platform. Other platforms are available for a different number of audio channels (from 2 channels, up to 32 channels). Please contact us to select the best solution for your requirements.

Audio Validation in Multimedia Systems and its Parameters

In the massive world of multimedia, sound stands as a vital component that adds depth to the overall encounter. Whether it's streaming services, video games, or virtual reality, sound holds a crucial role in crafting immersive and captivating content.

Using audio codecs IP as the digital audio hub in mobile multimedia systems

By integrating an audio analog codec that implements the 'audio hub' functionality and is able to process and mix audio signals from asynchronous sources, system designers can free the scarce main processor resources for more relevant tasks and simplify the system design, thus achieving a more effective solution.

Application Hardware Modeling: Selective modeling for early prediction of subsystem performances through simulation

The virtual validation of subsystem performances (Pop-up Noise, Signal-to-Noise Ratio, Power supply Noise, Power consumption...) requires the modeling and simulation of complete subsystems. Application Hardware Modeling (AHM) consists in addressing the risks of performance degradation while integrating a Silicon IP in its Integrated Circuit (IC) and this IC on its Printed Circuit Board (PCB). The selection of relevant models for a subsystem performance, along with the creation and validation of models through equivalence checking, are the basics of Application Hardware Modeling for right-on-first-pass subsystems!
