Title: Michael C. Whitfield: Patents in Multicore Processing and Voice Communications
Introduction
Michael C. Whitfield is an inventor associated with Valbonne, France, and has worked with Mindspeed Technologies, Inc. and Conexant Systems, Inc. His patent portfolio includes 7 patents, with inventions addressing multicore processing and the handling of DTMF signals in voice transmissions over IP networks.
Latest Patents
One of Whitfield’s latest patents, “Multi-core system with central transaction control,” describes a system in which a first processor manages transactions for multiple slave processing cores, such as coprocessors or digital signal processors. A system dispatcher generates transactions, while hardware drivers deliver them to the cores for execution. The system may also include a second processor that handles protocol processing.
His patent “Method and apparatus for early detection of DTMF signals in voice transmissions over an IP network” presents a way to identify in-band DTMF tones before transmitting voice packets. When a possible tone is detected, packets are temporarily buffered while a digital signal processor determines whether the signal is a valid DTMF tone. If it is, the buffered packets are discarded and a control packet conveys the tone information to the recipient. If it is not, the buffered packets are transmitted. This approach replaces DTMF tones in RTP transmissions with control packets.
Career Highlights
Whitfield’s listed company affiliations include Mindspeed Technologies, Inc. and Conexant Systems, Inc. The patents described here reflect work on processor coordination and reliable signaling in IP-based voice communications.
Collaborations
Whitfield’s listed coworkers include Jerome Vialle and Remy P. Gauguey. Their shared professional context connects them to the technology organizations associated with Whitfield’s career.
Conclusion
Michael C. Whitfield’s patent work spans multicore transaction control and the detection and transmission of DTMF signals over IP networks, illustrating contributions to both computing architecture and telecommunications.
