Latest Patents

One of Lin Li's latest patents is a graphics processing unit (GPU)-based logic rewriting acceleration method. This method involves parallelizing sub-procedures of And-Inverter Graph (AIG)-based logic rewriting. A recursive sub-procedure of the AIG-based logic rewriting is redesigned to be non-recursive, providing sufficient parallelism for a GPU. To parallelize a replacement step on the GPU, the method employs a lock to ensure mutually exclusive access, which can affect scalability of inter-node parallelism. To enhance this scalability, a work scheduler is proposed that adds nodes with non-overlapping maximum fan-out-free cones (MFFCs) to a group, allowing for simultaneous deletion of nodes without conflict. Additionally, a GPU-friendly graphical data structure is introduced to support concurrent operations of creating and deleting the same node.

Another notable patent is a power conversion module and power supply system. This module includes a power transistor and a sampling control unit. The sampling control unit determines a given duty cycle based on various reference duty cycles and controls the power transistor to maintain a target bus voltage. This innovation allows the power conversion module to operate at its maximum power point, stabilizing the direct current bus effectively.
