Title: Innovations of Eugene Jinglun Tam
Introduction
Eugene Jinglun Tam is a notable inventor based in San Jose, California. He has made significant contributions to the field of integrated circuits, holding two patents that showcase his innovative approach to technology. His work primarily focuses on boundary scan methods and configuration control in programmable logic devices.
Latest Patents
Eugene's latest patents include a boundary scan method for terminating or modifying integrated circuits. This JTAG Boundary Scan method allows for changes in the on-chip system logic (OCSL) of an integrated circuit through a state machine. This invention enables a predefined set of instructions to be loaded into an Instruction Register and executed in sequence after certain previous instructions. The instructions facilitate state changes in the OCSL without requiring a full device reset. Additionally, he has developed instructions that allow for self-timed termination within the integrated circuit and control the execution of instructions within the state machine.
Another significant patent involves configuration control in a programmable logic device using non-volatile elements. This invention utilizes a boundary scan test circuit (JTAG) interface to provide data for configuration latches within a Configuration Register. The Configuration Register is integrated within the JTAG structure as a Test Data Register (TDR). Each configuration bit consists of a Configuration Latch, which outputs a configuration control signal within an output logic macrocell. The input signal for the configuration register can be sourced from either a set of serially connected non-volatile element sense latches or from the JTAG Test Data In (TDI) data pin for purposes such as reconfiguration, prototyping, and testing.
