Tensilica HiFi DSPs add Maxim’s dynamic speaker management

December 10, 2015 // By Graham Prophet
Dynamic Speaker Management (DSM) software from Maxim Integrated Products has, Cadence reports, been ported to run on Cadence Tensilica HiFi Audio/Voice digital signal processors (DSPs).

Designers are typically faced with inherent problems, including weak sound and lack of bass response within micro speakers. In addition, these transducers can easily break and produce distorted sound. Maxim’s technology balances bigger sound and better sound quality with lower power and improved reliability against the increasingly smaller size of micro speakers available in the market today.

Maxim’s DSM technology improves audio performance in the following ways:

- Enriched bass and added ability to preserve stereo image

- Maximum protection through voice coil thermal protection and excursion limiting

- Voice interoperability compatible with speakerphone AEC

  • A low-cost solution that minimises hardware DSP redundancy


The Tensilica HiFi DSP licensable audio/voice/speech DSP family, offers support for over 160 audio/voice software packages and over 75 software partners in the Tensilica Xtensions partner program; www.cadence.com/news/HiFiDSP/Maxim

“Our DSM software in conjunction with our high-efficiency Boosted IV Sense Class D audio amplifier enables bigger sound, better sound quality, reduced power and improved reliability for micro speakers,” comments Jonathan Chien, Executive Director, Business Management at Maxim Integrated. “We utilise the HiFi DSP found in many mobile devices to efficiently run the DSM algorithm, providing OEMs with a complete audio solution.”

Larry Przywara, group director of Audio/Voice IP Marketing at Cadence adds, “Many of our mobile OEM and semiconductor customers are integrating Maxim’s DSM technology with our proven HiFi DSP cores to provide excellent sound quality and increased reliability with the micro speakers that are popular in today’s wearable- and mobile-driven marketplace.”
