Title: Jack Regula: Innovator in PCIe Technology

Introduction

Jack Regula is a prominent inventor based in Chapel Hill, NC (US), known for his significant contributions to the field of PCIe technology. With a total of 14 patents to his name, Regula has made remarkable advancements that enhance the functionality and efficiency of computing systems.

Latest Patents

Among his latest patents is the "Virtual Expansion ROM in a PCIe environment," which outlines methods and structures for utilizing a virtual Expansion ROM. This innovative management device includes a memory, a Peripheral Component Interconnect Express (PCIe) link, and a processor. The memory stores Expansion Read-Only Memory (Expansion ROM) boot instructions for a host. The processor identifies devices in a PCIe hierarchy by transmitting PCIe enumeration requests via the PCIe link. Additionally, it generates a synthetic PCIe hierarchy that includes an added virtual Expansion ROM, providing responses that describe this synthetic hierarchy to a host. The processor also acquires PCIe read requests initiated by the host directed to the virtual Expansion ROM, delivering boot instructions based on these requests.

Another notable patent is the "Switch with synthetic device capability," which presents a method for sharing a device's function with multiple hosts through a PCIe switch. This method allows a function on a device to be presented to both a first and a second host. The management system of the switch captures read and write operations on the function's register set within both hosts, enabling the creation of shadow copies of their register sets. This innovation facilitates efficient management of read and write operations from both hosts.
