Title: Douglas L. Terrell: Innovator in Microprocessor Testing
Introduction
Douglas L. Terrell is a notable inventor based in Pflugerville, TX (US). He has made significant contributions to the field of microprocessor testing, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
Terrell's latest patents include a "System and method for controlling synchronous functional microprocessor redundancy during test and analysis." This system is designed for testing processors and includes a gold processor and a test access port (TAP). The device under test (DUT) is coupled to both the gold processor and the TAP. Test signals are provided simultaneously to both processors, allowing them to operate in synchronous functional lockstep. The TAP can also input test signals into both processors and access data through separate test data out (TDO) connections. The comparison of test output data from the gold processor and the DUT is crucial for determining any discrepancies, which can then be analyzed for further insights.
Another patent by Terrell is also titled "System and method for controlling synchronous functional microprocessor redundancy during test and method for determining results." This system operates in multiple modes, allowing the TAP to provide test signals to either the gold processor or the DUT, or both simultaneously. A host computer executes a software application to drive test signals and access test output data, facilitating a thorough comparison and analysis of results.
