Latest Patents

Choi's latest patents showcase his innovative approach to addressing challenges in integrated circuit performance:

1. **Compiler that generates configuration information for configuring an integrated circuit to mitigate inductive-induced voltage droop**

This invention involves a method that analyzes a dataflow graph to generate configuration information loadable into an integrated circuit. The dataflow graph specifies operations to be performed and data dependencies between these operations. This configuration information is essential for the integrated circuit to manage compute units effectively, control data flow, and mitigate supply voltage droop caused by changing current drawn through inductive loads.

2. **High-bandwidth power estimator for AI accelerator**

This patent describes a processor integrated circuit (IC) featuring multiple power base units (PBUs) arranged in an array. Each PBU incorporates a switch, memory unit, and compute unit, along with a power estimator for each component. It enables time-accurate aggregate power estimates through dedicated wiring and timestamps. The array-level power accumulator calculates nominal dynamic power estimates while a power clock management controller refines the estimates based on clock frequency and supply voltage.
