    摘要: Disclosed are a system and method of transmitting data frames between media independent interfaces (MIIs) in a bus conversion device. Data frames received at a first MII may be formatted according to a first data transmission protocol. A bus conversion device formats the data frame for forwarding to a second MII. The bus conversion device may transmit data frames between MIIs having different associated data rates and data frame formats.

    摘要: Disclosed are a system, method and device for negotiating a data transmission mode over an attachment unit interface (DDI). A data transceiver circuit may be coupled to one or more data lanes of the DDI. A negotiation section may receive a link pulse signal on at least one data lane in the DDI during a negotiation period and selectively configure the data transceiver to transmit and receive data on one or more data lanes according to a data transmission mode based upon the received link pulse signal.

    摘要: Described are a device and system to transmit data to or receive data from one or more data lane interfaces. Each data lane interface may be capable of transmitting a serial data signal to or receiving a serial data signal from a data lane in a device-to-device interconnection. An effective data rate may be varied based, at least in part, upon a number of the data lane interfaces actively transmitting a serial data signal to or receiving a serial data signal from the device-to-device interconnection.

    摘要: A system and method for auto-polling a status register within a physical layer (PHY) interface to a local area network (LAN). The system includes a host CPU which needs to detect and service interrupts generated by a PHY device on the LAN which is coupled between a first transmission medium (such as copper or fiber cable) and a management interface to the system. The system further includes an auto-polling unit which monitors activity on the management interface of the PHY device. When the auto-polling unit detects a lack of activity on the management interface of the PHY for a predetermined interval, the auto-polling unit reads a first value from the PHY status register. This first status value is then compared to a previously stored value which corresponds to the last PHY status value read by the host CPU. If a mismatch is detected between these two values, an interrupt is generated to the CPU. In response to receiving the interrupt, auto-polling is suspended (to avoid changing the status data that caused the interrupt) and the CPU requests a read of the status value in the first register. In this manner, the CPU is able to access the status value which caused the interrupt and determine the appropriate course of action. This status read by the CPU also has the effect of clearing the interrupt. This system frees the CPU from having to continually poll the PHY status register to determine if a change in status has occurred.

    摘要: An interface and related methods for rate pacing in an Ethernet architecture are described herein. In an embodiment, an effective data rate of communication channel with a remote network device is reduced based, at least in part, on an identified processing capability of the remote network device. In one embodiment, to reduce the effective data rate, one or more idle control elements are inserted between at least two frames of substantive content based, at least in part, on the processing capability of the remote network device. Other embodiments are also disclosed.
