  • Power Aware Scheduling for Real-Time Embedded Systems (Funded by NSF): The goal of this project is to study the stringent power/energy constraints on real-time embedded systems. Particularly, we are interested in developing system level novel tasks scheduling schemes to match the power/energy consumption thresholds without affecting the desired timeliness of task sets.


Developed an Accurate and Reliable System Power and Thermal Models for Single Core and Multicore Architectures

Using a Novel, Fast, Light Weight and Accurate System Level Energy Estimation Method, Conducted a Comparative Study of Various Energy Efficient Task Scheduling Methods

Developed an Efficient and Fast Synthetic Simulation Platform using MATLAB, C++, Perl

Developed a Practical Simulation Platform Combining, Architecture Level Simulators, SimpleScalar and HotSpot, to Test Different Scheduling Techniques with Industry Standard Benchmarks


  •  Leakage Aware Temperature-Constrained Scheduling for Real-Time Embedded Systems (Funded by NSF): The research objective of this project is to address the temperature and power/energy consumption issues in real-time embedded systems, with a special focus on the adverse impact of the strong relationship between temperature, leakage power and over all power consumption on the performance of microprocessors.


Incorporating Critical Leakage-Temperature Dependency into System Models Developed an Effective Scheduling Scheme “M-Oscillations” to Minimize the Peak Temperature of the Processors.

Proposed Several Fundamental Principles to Minimize the Peak Temperature on Single Core Processors

Addressed Issues Related to Performance Optimization under Maximum Temperature Constraints

Closely Studied the Neighboring Effects on the Thermal Dynamics of a Core on Multicore Processors

Developed Task Feasibility Analysis Methods on Multicore Processors

Developed Simulation Platform using C++, MATLAB, Perl, HotSpot and SimpleScalar to Validate the Accuracy and Effectiveness of Proposed Algorithms and Theorems


  • Power/Thermal Efficient 3D-Multicore System Designs: This is an on-going project focusing on the development of better system level resource management methods to address power/thermal efficiency in 3D stacked multicore architectures. The goal is to develop novel dynamic thermal management and energy minimization techniques employing better task scheduling and speed selection methods. We also seek to develop thermal-aware 3D architectures incorporating novel cooling strategies like inter-tier liquid cooling.
Internship Experience Validation Intern (Micro-Electronics Group), SUN Microsystems, Burlington, MA, USA, Summer-2007

  • Simulation and Debug of Processors and ASIC’s in the High End Server System: This experience provided an opportunity to work in the state of the art verification environment at Sun Microsystems. The task was to work in collaboration with other engineers in validating the next generation CMT processors.
