Title: Bruce A Long: Innovator in Processor Behavioral Models
Introduction
Bruce A Long is a notable inventor based in Loveland, Colorado. He has made significant contributions to the field of processor behavioral models, holding 2 patents that showcase his innovative approach to verifying the correctness of microcode machines.
Latest Patents
One of his latest patents is titled "Method and apparatus for verifying the correctness of a processor behavioral model." This invention provides an apparatus that verifies the correctness of a behavioral model of a microcode machine, which operates in both native and emulated states. The apparatus includes means for producing both states and comparing them to ensure accuracy. The corresponding method involves determining if a macroinstruction is a native instruction and executing it accordingly, ultimately comparing the native and emulated states of the processor.
Another significant patent by Bruce A Long is "Method and apparatus for verifying the fine-grained correctness of a behavioral model of a central processor unit." This invention checks the fine-grain correctness of a CPU behavioral model by decomposing macroinstructions into microinstructions and executing them sequentially. The method utilizes an emulated microinstruction sequencer to determine the sequence of execution, comparing reference states to the behavioral model at each step.
