Title: Nitij Mangal: GPU State Management Inventor

Introduction

Nitij Mangal is an inventor based in Santa Clara, California, and is associated with Nvidia Corporation. His patent work addresses graphics processing unit (GPU) state management, an important capability for handling context switches in multi-threaded processors.

Latest Patents

Mangal is named on 1 patent: “Apparatus and Method for Serial Save and Restore of Graphics Processing Unit State Information.” The invention describes a GPU architecture in which two processing controllers manage separate sets of multi-threaded processors. When a context switch token is received, the first controller gathers state information from its processors and passes the token over a serial bus to the second controller, which then gathers state information from its own processors. This serial process supports saving and restoring GPU state across the two processor groups.

Career Highlights

Mangal’s patent reflects work on GPU architecture and the coordination of processor state during context switches. The disclosed approach uses a serial connection between processing controllers to sequence the collection of state information from multiple processor groups.

Collaborations

Mangal’s listed coworker is Roger L. Allen. The patent information provided identifies their professional association but does not specify their respective roles in developing the invention.

Conclusion

Nitij Mangal’s patent focuses on serially coordinating GPU state collection across multi-threaded processor groups, highlighting a practical contribution to graphics processing architecture.
