Power Consumption and Performance of a Wearable Computing System

چکیده
The Smart Module project generates a family of interoperable modules supporting real-time Speech Recognition, Language Translation, and Speech Synthesis. The hardware, software, and physical form factor of the modules functions less like a computer and more like a tool or an appliance. Power Consumption and Performance are key design goals for wearable systems. This paper examines the effect that various design factors have on these metrics. While processor speed and type do affect power consumption and performance, memory size and type of secondary storage have the greatest influence on these goals. In particular, the time it takes to swap information out of main memory can reduce the performance of a wearable system by more than half. Finally, a method for modeling Speech Recognition performance to within 10% accuracy is discussed. Project Supervisor: Daniel P. Siewiorek Title: Professor This project was funded under DARPA Contract DABT 63-95-C-0026
