Reconfigurable Systems
What should reconfigurable hardware look like when the workload, technology, and operating conditions can all change?
Perspective
Reconfigurable computing offers a productive middle ground between fixed-function efficiency and software flexibility. My research spans arithmetic operators, accelerator architectures, dynamic partial reconfiguration, and the underlying fabric itself.
FPGA accelerators
Resource-efficient implementations for AI, reinforcement learning, spiking networks, and edge processing.
Dynamic adaptation
Partitioning, lifetime awareness, and design automation for partially reconfigurable systems.
