Energy-efficient reliability in real-time embedded systems (RTES)
One of the most important challenges faced by designers of next-generation RTES is the efficient management of energy and power. RTES typically operate using limited power source and suffer from increasing chip power density and lack of heat sink. Further, high power consumption also has an adverse impact on hardware reliability (including chip burn-outs). This project focuses on the joint investigation of reliability, feasibility, and energy efficiency in hard RTES which operate under extreme and unpredictable environments.
Real-time multi-core/processor systems
The marketplace for Real-Time Embedded Systems (RTES) is growing at an exponential rate and several new paradigms are being proposed to satisfy the conflicting need for performance and portability. One of the most promising approach comprises emerging class of chip-multiprocessors (CMP) and distributed multiprocessors (DMP) systems which are characterized by several properties novel to real-time systems: (1) increasingly complex architecture due to tighter integration, multi-hierarchical memories, more involved communication protocols, and advanced features such as deeper pipelining and simultaneous multi-threading, (2) replacement of wired medium with inherently unreliable and unpredictable wireless medium, (3) powering on batteries with limited charge capacity, (4) operation under harsh, unpredictable, and widely varying conditions, and (5) frequent deployment in remote locations with minimal accessibility. This research project focuses on investigating and optimizing the impact of above mentioned characteristics on various RTES performance metrics.
