Ittiam unveils its audio codecs and algorithms for the ARM Cortex-M4 processor

Ittiam has made available audio codecs and post-processing algorithms for ARM Cortex-M4 processor. The ARM Cortex-M4 processor is suitable for digital signal control applications such as motor control, automotive, power management, industrial automation and embedded audio markets.

Ittiam's audio codecs have been optimized to take advantage of the Single Instruction Multiple Data (SIMD) unit and enhanced DSP instructions of the Cortex-M4 processor, enabling a two times performance gain over the Cortex-M3 processor implementations.

Ittiam says that its audio codecs and algorithms includes an 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 better 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. "Ittiams 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."
