Title: Innovations by Rebecca Stempski McMahon

Introduction

Rebecca Stempski McMahon is a notable inventor based in San Jose, CA. She has made significant contributions to the field of data processing and networking technologies. With a total of 2 patents, her work has had a substantial impact on the efficiency of data transfer and network communication.

Latest Patents

One of her latest patents is the "Direct Memory Access Acceleration Device for Use in a Data Processing." This device is designed to substantially increase the data transfer rate between system memory and Input/Output (I/O) devices. The DMA Acceleration Device enables the system to nearly double the data transfer rate by generating necessary control and address signals. During a receive operation, it reads data from the I/O device while the host processor writes previous data to the system memory. Conversely, in a transmit operation, it writes data to the I/O device while the host processor reads subsequent data from the system memory. The device's Transmit and Receive State Machines are programmed to control the sequencing of signals during DMA mode, remaining transparent to the system in non-DMA mode.

Another significant patent is the "FDDI Network Test Adapter History Store Circuit (HSC)." This circuit is employed with a commercially available FDDI chipset to provide an interface between the PHY layer hardware and a memory system. It records symbol stream segments received from the FDDI network. The HSC includes multiplexor logic to support dual-ring network configurations and provides the necessary electrical interconnection to interface with the PHY layer hardware. This allows for the reception of both valid and invalid frames, as well as invalid/valid line state symbol streams from the fiber optic bus. The HSC also features a Symbol Stream Comparator and History Store Triggering Logic to facilitate control over the network traffic segment captured.
