CorePool FHG

FHG MP3 Decoder Software

Purpose

The MPEG 1/2 Layer 3 (MP3) decoder offered as CorePool software IP for the audio platform is designed to fulfill the requirements for a "Full Layer 3 ISO/IEC 11172-3 audio decoder" as laid down in ISO/IEC 11172-4. The decoder incorporates Fraunhofer IIS's distinct knowledge in high quality audio coding as it is based on Fraunhofer IIS's fixed point reference decoder. It passes the conformance testing procedure defined in ISO/IEC 11172-4, Section 2.6.3

Features

Runs on the ARCtangent^TM-A4 microprocessor core (backward compatible to ARC3)

Layer 3 ISO/IEC 11172-3 audio decoder

High ("un-limited") accuracy

Supports stereo, joint stereo, dual and single channel audio streams

Bit rates from 8 to 320 kbits/s (MPEG 1, MPEG 2 and FhG proprietary extensions)

Sampling frequencies from 8 to 48 kSamples (MPEG 1, MPEG 2 and FhG proprietary extensions)

Supports "free format" bit streams

Modular software design

Configurable and adaptable for various system requirements

Passes conformance tests based on ISO/IEC 11172-4

This IP shares a common set of target specific functionality and drivers with other CorePool software IPs for the audio platform. This requires minimum initial adaption of these drivers to the target system and enables the system integrator to switch between - or to support - multiple audio standards.
