Title: Rahul Dev and Debugging Across Dynamic Power Domains.

Introduction

Rahul Dev is an inventor based in Santa Clara, California, and is associated with Advanced Micro Devices Corporation. His patent work addresses how to preserve debug visibility in integrated circuits when parts of a chip are powered down.

Latest Patents

The provided information identifies one patent associated with Dev: “Debug Apparatus and Methods for Dynamically Switching Power Domains.” The invention describes methods and apparatus for debugging components in dynamically controlled power domains. In one implementation, an integrated circuit has hardware sectors with observability circuits connected to a debug circuit’s data bus. When a sector is powered off while another remains active, a debug data register can supply configuration or programming data to the powered-down sector’s observability circuit. A shadow register captures that data so the circuit’s prior state can be restored when power returns. This approach is intended to maintain debug observability through power transitions. Dev is credited with 1 patent in the information provided.

Career Highlights

The available details connect Dev’s patent activity with Advanced Micro Devices Corporation and identify his work on debug support for integrated circuits with dynamically switched power domains. The patent focuses on retaining and restoring observability data across power events.
