DSM optimized software implementation integrated into smartphone SoC


CEVA has announced the availability of Dynamic Speaker Management (DSM) software from Maxim Integrated Products, for the CEVA-TeakLite-4 family of ultra-low power audio/voice DSPs. The DSM optimized software implementation running on CEVA-TeakLite-4 is already integrated into a smartphone SoC from a Tier-1 smartphone OEM.

Many devices, including smartphones, headsets and wearables encounter significant challenges when it comes to speaker design. The requirement for increasingly smaller micro speakers and the power constrains in these devices severely limits the sound quality possible using conventional D-class amplifiers. DSM running on the CEVA-TeakLite-4, together with Maxim’s boosted IV sense Class D speaker amplifiers overcomes these challenges, delivering a much richer sound experience with 2.5x louder sound and two octaves deeper bass versus conventional Class D amplifiers.

“At Maxim, we are constantly pushing the boundaries of the sound quality possible from micro speakers, creating louder and richer listening experiences for our customers,” said Jonathan Chien, managing director and general manager of Audio Solutions at Maxim.

“DSM on the CEVA-TeakLite-4 DSP is already proven with a tier-1 smartphone OEM, and offers an exceptional solution for any speaker-constrained and power-sensitive mobile device.”

“Consumers increasingly expect powerful sound from their mobile devices, despite the incredible small form factor and power budget constraints of smartphones, wearables and alike,” said Moshe Sheier, director of strategic marketing at CEVA. “The combination of Maxim’s DSM technology and our ultra-low-power CEVA-TeakLite-4 audio/voice DSP provides rich, powerful sound from even the smallest of micro speakers, without compromising reliability and power efficiency of the device.”
