Title: Joseph Tatham: Innovator in Virtual Hardware Models

Introduction

Joseph Tatham is an accomplished inventor based in Carlisle, MA (US). He has made significant contributions to the field of virtual hardware modeling, holding 2 patents that showcase his innovative approaches to simulation acceleration and processing.

Latest Patents

Tatham's latest patents include "Multimode execution of virtual hardware models." This patent describes various methods and systems for accelerating the execution of a virtual prototype simulation. Acceleration is achieved by providing two or more redundant virtual communication paths for access made by virtual models of a hardware design. This allows for both accelerated access transactions and time-accurate access transactions. A model with such redundant virtual communication paths is referred to as a 'multimode model.'

Another notable patent is "Partitioning and parallel processing of a virtual prototype simulation of a hardware design." This method involves accessing a first virtual prototype configured to perform a first simulation of a hardware design. It identifies checkpoints within the first virtual prototype, each checkpoint including a storage state and/or behavioral state. The method determines breakpoints for dividing execution of a second virtual prototype into a series of execution segments. The second virtual prototype is configured to perform a second simulation of the hardware design, with virtual models representing separate portions of the hardware design.
