Title: Innovative Intel Inventor: Sarathy Jayakumar

Introduction:

Sarathy Jayakumar, an experienced inventor based in Portland, Oregon, is a prominent member of the research and development team at Intel Corporation. With an impressive portfolio of 34 patents, Jayakumar has contributed significantly to the field of computer architecture and system design.

Patent Highlights:

Among his notable patents, two innovations stand out: "Apparatus and Method to Identify the Source of an Interrupt" and "CPU Hot-Swapping." Let's take a closer look at each of these groundbreaking inventions.

1. Apparatus and Method to Identify the Source of an Interrupt:

This patent describes an apparatus and method for processing non-maskable interrupt (NMI) source information. Jayakumar's invention involves a processor with multiple cores, each equipped with execution circuitry to process instructions and data. The local interrupt circuitry, which consists of registers storing interrupt-related data, is capable of storing NMI data and NMI source information. Additionally, the patent describes a selection circuitry that enables the processor to choose between different modes for processing NMIs, depending on the inclusion of NMI source information. This invention enhances interrupt handling capabilities by providing essential information for efficient debugging and error diagnosis.

2. CPU Hot-Swapping:

Jayakumar's second patent addresses the issue of hot-swapping CPUs in a multi-core computing system. The invention introduces a method to facilitate the replacement of a malfunctioning or outdated CPU without disrupting the overall system functionality. By utilizing switch technology and non-transitory instructions, the patent enables the detection of a hot swap event and subsequently designates a new CPU to replace the faulty one. The switch effectively communicates with a backup initialization code store, ensuring a seamless initialization and integration of the new CPU into the system.

Collaboration and Impact:

Jayakumar collaborates with esteemed colleagues such as Mohan J Kumar and Ashok Raj, who are also involved in driving innovation at Intel Corporation. Their combined expertise and dedication have contributed to the creation of cutting-edge technologies that advance Intel's presence in the market and establish it as a leader in semiconductor manufacturing.
