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.
