He holds 2 patents that showcase his innovative approach to integrated circuit design and digital integration techniques. Greene's work has been instrumental in advancing communication technologies.
Latest Patents
One of Greene's latest patents is a DSP co-processor designed for use on an integrated circuit that performs multiple communication functions. This invention includes a data bus interface, a sequencer, internal memory, and a data core. The sequencer stores a signal processing algorithm in a hardware format and, upon receiving an operational command, provides address control signals and operation control signals to the data core. The data core executes operational instructions of the signal processing algorithm to produce resultant signals from input samples.
Another significant patent is a digital integrator that reduces circuit area and power consumption. This invention implements a two-stage integration for a decimator using only one adder. The transfer function of this two-stage integrator can be expressed in the z-domain, and the inverse z-transform yields an expression that can be implemented with a single adder and two delay portions. This innovative approach allows for further integration within a single adder circuit by time-multiplexing the required additions.
