    摘要: A method and apparatus for managing memory for time division multiplexed high speed data traffic is provided. The method and apparatus utilize an interleaving approach in association with multiple memory banks, such as within SDRAM, to perform highly efficient data reading and writing. The design issues a first command or access command, such as a read command or write command to one memory bank, followed by an active command to a second memory bank, enabling efficient reading and writing in a multiple data flow environment, such as a SONET/SDH virtual concatenation environment using differential delay compensation.

    摘要: Systems and methods of operating root hub host controllers provide for determining, at a protocol engine having a dedicated port, a speed of a device in response to a coupling of the device to the dedicated port. Data transfer can occur at a second speed between software interface logic of the host controller and the protocol engine, and at the first speed between the protocol engine and the device via the dedicated port, wherein the second speed is greater than the first speed. In addition, data may be transferred in unicast transactions in which no split tokens are exchanged.
