Abstract

Speech recognition is an important application which requires large amount of computation and data. We parallelized speech recognition on ARM11-mpcore, one of the mobile multi-core processors. We achieved 1.92 times speed-up using four cores. We argue that this is sufficiently close to the theoretical best regarding Amdahl's law. We also evaluated it on Intel Core2Quad to derive requirements for future mobile multi-core platforms.
