Title: Martim Carbone: Innovator in CPU and Virtualization Technologies

Introduction

Martim Carbone is a prominent inventor based in Palo Alto, California. He has made significant contributions to the field of computer science, particularly in CPU privilege management and virtualization technologies. With a total of five patents to his name, Carbone continues to push the boundaries of innovation in his field.

Latest Patents

One of Carbone's latest patents focuses on techniques for reducing CPU privilege boundary crossings. In this invention, an operating system (OS) kernel can receive an invocation of a system call from a user program. The OS kernel fetches subsequent instructions that will be executed by the user program and decodes them. It then analyzes whether these instructions include additional system call invocations and whether other instructions in between are viable for emulation.

Another notable patent involves supporting invocations of the RDTSC (Read Time-Stamp Counter) instruction by guest code within a secure hardware enclave. This invention allows a hypervisor to activate time virtualization heuristics for a virtual machine (VM). The hypervisor determines a scaling factor for timestamps generated by physical CPUs in response to CPU instruction invocations made by guest program code.
