Oticon hearing aids - highly optimized multi-processor systems on chip
Mogens Cash Balsby - Oticon
Abstract:
State of the art hearing aid solutions increase speech understandability, while maintaining a spatial awareness and natural hearing. This is achieved from extremely small devices delivering massive computational power/watt, while communicating wirelessly and operating more than a week on a tiny battery. To achieve this, small highly optimized chipsets are developed. We will present some of the physical constraints that exist on the chipsets and how these are packaged for size and performance. In addition we will present the design goals and constraints that lead to the chipset architecture such as NOC system, IC interconnect and processor architecture.
Biography:
Born 1966. Bachelor of Science in Electrical Engineering, Computer Eng. from Technical University of Denmark in 1990.
Mogens Cash Balsby is employed in Oticon, as responsible for IC development in William Demant group, which develops its own chipset from the ground up. These chipsets are used in all three brands; Oticon, Bernafon and Sonic. They are characterized by very high computational power pr watt, and the ability to communicate wirelessly using extremely little power. Prior to this, Mogens headed the development of MIPS Technologies' first 64bit synthesizable CPU core, MIPS64 5Kc and associated IEEE compliant FPU. Additional MIPS processor development was done in LSI Logic Inc, and prior to this, Mogens worked in the networking industry architecting and designing some of the world’s first 10/100Mbit stackable switches, purely based on ASIC technology.
