Multi-Chiplet Architectures

Emerging 2.5D and 3D multi-chiplet architectures create coupled challenges across temperature, data movement, workload mapping, and hardware specialization. My work in this area spans thermal-management challenges in heterogeneous integration, multi-fidelity thermal modeling for fast design exploration and runtime management (MFIT), thermally-aware scheduling for heterogeneous multi-chiplet PIM systems (THERMOS), co-simulation of deep learning workloads on chiplet platforms (CHIPSIM), energy-efficient heterogeneous chiplet inference architectures (HeMu), and lossless exponent coding for inter-chiplet communication in hybrid LLMs (LEXI).

Together, these projects improve how chiplet-based systems are modeled, scheduled, and architected for efficient AI inference under thermal, bandwidth, and energy constraints.

Hardware Accelerators for ML models

My accelerator research targets efficient execution of modern ML models across edge and datacenter systems. Recent work includes DUET, a disaggregated accelerator for hybrid Mamba-Transformer LLM inference with prefill/decode-specific packages, and eMamba, an efficient acceleration framework for Mamba models in edge computing. My earlier work also explored automated FPGA acceleration for tree-based ML models through LightFPGA.

Runtime Optimization using Machine Learning

Dynamic runtime optimization focuses on balancing latency, energy, temperature, and resource utilization in heterogeneous computing systems. My work in this area includes THERMOS, which performs thermally-aware multi-objective scheduling for AI workloads on heterogeneous multi-chiplet PIM architectures, and runtime monitoring techniques that make ML-based schedulers more robust for Domain-Specific SoCs (DSSoCs). Together, these frameworks improve performance and energy efficiency while managing dynamic workloads, resource contention, and thermal constraints.

Approximate Computing and Applications

Approximate computing trades accuracy for efficiency, making it a perfect fit for energy-constrained systems and error-resilient applications.

I worked on several exciting projects in this area, such as developing ReARM, a reconfigurable approximate multiplier, and ACA-CSU, a carry-selection-based adder, to optimize power and performance for tasks like image processing. My work extended to ApproxBioWear, targeting efficient arithmetic for wearable biomedical devices, and even explored the feasibility of approximation in communication systems. Most recently, Ellora applied these concepts to create low-power radar processors, blending approximate computing with advanced OFDM techniques.
