Subrahmanyam Mula received the B.E. degree in electronics and communication engineering from Andhra University, Visakhapatnam, India, in 2001, and the M.Tech. degree in microelectronics and VLSI design from IIT Kharagpur, Kharagpur, India, in 2003, and Ph.D. degree from Department of Electronics and Electrical Communication Engineering, IIT Kharagpur, Kharagpur, India, in 2018. From 2003 to 2014, he was with Intel, Bengaluru, India, where he was involved in front-end design verification of gigabit Ethernet switches, processors, chip-sets, and GPUs. He has experience in building strong design verification teams, leading them, coordinating with multiple stake holders across sites (India, US, Israel and Malaysia) and delivering to projects. He supported six generations of Intel GPUs from Eaglelake (Gen4) on 65nm to Skylake (Gen9) on 14nm at various levels such as architecture, RTL, Verification, GLS, STA, DFT and Post Si Debug. He made significant contributions to 32nm Sandy Bridge processor that first time integrated 4 high performance Intel Architecture (IA) cores, a power/performance optimized GPU, memory and PCIe controllers in the same die. His current research interests include VLSI architectures for real time signal processing applications and adaptive learning systems.

My research interests span the broad area of VLSI architectures for statistical signal processing algorithms. My current research mainly focuses on developing efficient VLSI architectures for real-time adaptive filtering applications. For achieving the best performance-flexibility trade-off of the complex adaptive filtering algorithms, I focus on co-design of algorithm and architecture in an intertwined way rather than designing them in isolation.
