Title: Ravi S. Rao and Real-Time Performance Monitoring

Introduction

Ravi S. Rao is an inventor associated with Phoenix, Arizona, and Intel Corporation. His patent work includes an integrated facility for monitoring performance events in data-processing hardware. The supplied information lists 5 patents.

Latest Patents

One of Rao’s latest listed patents is titled “Integrated Real-Time Performance Monitoring Facility.” The invention describes a monitoring system integrated into an integrated-circuit data processor. It tracks bus-related events, including device acquisition and ownership time, as well as the number of requests and grants on a bus.

Integrated event counters record both event occurrences and durations. The facility can notify software when a counter overflows, helping software monitor processor activity. It can also track events across multiple clock domains, including bus interfaces operating at different frequencies.

In one described embodiment, the monitoring facility is integrated into an I/O processor die designed to comply with Intelligent I/O and Peripheral Component Interconnect specifications. The supplied patent description appears twice in the provided information, so it is presented here as one invention.

Career Highlights

Rao’s listed work focuses on hardware performance monitoring and the measurement of activity within integrated circuits. The described invention provides software with access to detailed information about bus behavior and processor events.

Collaborations

The supplied information identifies Elliot D. Garbus and Byron R. Gillespie as Rao’s coworkers. It does not specify their roles in the patent or describe particular collaborations.

Conclusion

Ravi S. Rao’s listed patent work at Intel Corporation centers on integrated, real-time monitoring of processor and bus activity, enabling software to observe hardware events across different operating conditions.
