Abstract

The integration of application specific instruction set processors (ASIPs) in hearing aids requires various architectural customizations and software-side optimizations in order to meet the stringent power consumption constraints and processing performance demands. This paper presents the KAVUAKA application specific hearing aid processor and its ASIC integration as a system on chip (SoC). The final system contains four KAVUAKA processor cores and ten co-processors. Each of these processors and co-processors were individually customized and differ in their data path width. The processors are organized in two clusters, which share memories, an audio interface, co-processors and a serial interface. With this system, different hearing aid systems are evaluated in terms of performance, power and area by activating different processor and co-processor combinations. A 40 nm low power technology was used to build this research hearing aid system. The die size is 3.6 mm 2 with less than 1 mm 2 per core. The measured average power consumption is less than 1 mW per core.
