摘要： A system and method for handling speculative read requests for a memory controller in a computer system are provided. In one example, a method includes the steps of providing a speculative read threshold corresponding to a selected percentage of the total number of reads that can be speculatively issued, and intermixing demand reads and speculative reads in accordance with the speculative read threshold. In another example, a computer system includes a CPU, a memory controller, memory, a bus connecting the CPU, memory controller and memory, circuitry for providing a speculative read threshold corresponding to a selected percentage of the total number of reads that can be speculatively issued, and circuitry for intermixing demand reads and speculative reads in accordance with the speculative read threshold. In another example, a method includes the steps of providing a speculative dispatch time threshold corresponding to a selected percentage of a period of time required to search a cache of the computer system, and intermixing demand reads and speculative reads in accordance with the speculative dispatch time threshold.

摘要： A method for handling speculative access requests for a storage device in a computer system is provided. The method includes the steps of providing a speculative access threshold corresponding to a selected percentage of the total number of accesses to be speculatively issued, and intermixing demand accesses and speculative accesses in accordance with the speculative access threshold. In another embodiment, a method for reducing data access latency experienced by a user in a computer network is provided. The method includes the steps of providing a web page comprising a link to a data file stored on a database connected to the computer network, selecting a speculative access threshold corresponding to a selected percentage of data accesses which are to be speculatively provided to the user, and speculatively providing the data file in accordance with the speculative access threshold.

摘要： The decision within a packet processing device to transmit a newly arriving packet into a queue to await further processing or to discard the same packet is made by a flow control method and system. The flow control is updated with a constant period determined by storage and flow rate limits. The update includes comparing current queue occupancy to a threshold. The outcome of the update is adjustment up or down of the transmit probability value. The value is stored for the subsequent period of flow control and packets arriving during that period are subject to a transmit or discard decision that uses that value.

摘要： A system and method for remotely powering an Ethernet network repeater through an attachment unit interface (AUI) between the repeater and a remote personal computer (“PC”) or workstation. The AUI includes logic circuitry to detect when the Ethernet is supporting a transmit signal and a receive signal. Associated with the AUI is a DC to DC converter which receives, remotely through the AUI interface, a DC voltage from the PC or workstation and converts the DC voltage into working voltages for the remote repeater.
