Ittiam Systems Unveils its Audio Processing Software for the ARM Cortex-M4 Processor

Broad Set of Audio Codecs and Algorithms for the latest ARM Cortex-M Processor

Bangalore — March 02, 2010 — Ittiam today announced the availability of audio codecs and post-processing algorithms for the newly released ARM® Cortex™-M4 processor.

The ARM Cortex-M4 processor is the most efficient processor of the Cortex-M series for digital signal control applications and has been designed to answer the needs of the motor control, automotive, power management, industrial automation and embedded audio markets.

Thanks to its compatibility with the Cortex-M processor series, the existing codec offering from Ittiam on the Cortex-M3 processor is fully functional out-of-the-box with a 10 percent performance improvement on the Cortex-M4 processor. Additionally, Ittiam audio codecs have been fully optimized to take advantage of the Single Instruction Multiple Data (SIMD) unit and enhanced DSP instructions of the Cortex-M4 processor, enabling a 2 times performance gain over the Cortex-M3 processor implementations.

Ittiam's product offering for the Cortex-M4 processor includes a fully optimized implementation of MP3 and WMA decoders, with a roadmap for additional portable and high definition audio codecs later this year. These codecs are complemented by a set of audio effects and acoustic processing algorithms to provide to the end user a rich listening experience.

"The Cortex-M4 processor is well suited for audio processing," stated Shantanu Jha, Vice President Media Processing at Ittiam Systems. "Advanced features like the single cycle MAC, DSP instructions with SIMD capability enable efficient audio signal processing on this MCU core. Combining the microcontroller and signal processing features at low power, the Cortex-M4 processor is an attractive solution for the embedded market."

"The Cortex-M4 processor addresses a wide variety of digital signal control markets and embedded audio is one of the most challenging in terms of signal processing requirements," said Shyam Sadasivan, Product Manager for the Cortex-M4 processor at ARM. "Ittiam's expertise on the Cortex-M processor family has enabled us to address these requirements through a combination of leading processor architecture and highly optimized software that will help our customers get products to market faster."
