Research Interest

Major Research Area: Computer Architecture and Hardware Security

Click here to understand the importance of research in Computer Architecture. 

My research area is mainly focused on memory architecture of Chip-multiprocessors (CMPs). I have been working in this area for more than ten years. My main focus is on improving the efficiency (performance and energy consumption) of Last Level Cache (LLC) for Tiled CMPs (TCMP) and the main memories. During my Ph.D. I have proposed techniques to reduce the miss rate of LLCs in TCMP. After my Ph.D., I have extended my research areas into Main Memories and Non-Volatile Memories (NVM). For the last few years, I am actively working on Hardware Security of CMPs as well as Main Memories. Most of the research challenges on which my group is working will be faced by the future generation processors.
