Sensor-based infrastructures are important base technology for cooperative media spaces that support the natural interaction of users with their physical environment and with other users beyond the traditional keyboard and mouse. Sensor-based infrastructures basically capture data from sensors, store and process these data, and provide the data to clients. Several infrastructures have been developed;...
The sustained push for performance, transistor count and instruction level parallelism has reached a point where IC thermal issues are at the forefront of design constraints. Many of the current systems deploy dynamic voltage and frequency scaling (DVFS) to address thermal emergencies. DVFS has certain limitations in terms of response lag, scalability and being reactive. On the other hand, several...
