  • Method and system for assigning peripheral device addresses
    Patent number: 5640594
    Abstract: A system for relocating expansion cards within a personal computer is provided that eliminates the need for manually changing the address locations. By examining both the address and the data of I/O accesses, the system provides security against accidental reprogramming of the device. Through the use of this system, both hardware implementation and the time needed to execute the reprogramming operation is minimized.

  • System and method for a flexible MAC layer interface in a wireless local area network
    Patent number: 5636140
    Abstract: A system and method for providing a flexible medium access control device. The medium access control (MAC) device includes four configurable transmit and receive modes for communicating with a physical layer signaling control device. The four modes are controlled by a processor and a transceiver interface. In operation, the modes enable the MAC device to transmit and receive MAC data to and from the physical layer signaling control device, and to optionally transmit and receive PHY data to and from the physical layer signaling control device, thereby providing compatibility between a MAC device and a radio, regardless of the physical layer functionality of the radio.
