    摘要: Systems and methods of operating a computing system may involve utilizing at least one of a peripheral protocol negotiation and a universal connector to determine a peripheral device protocol, and reconfiguring a computer device to accommodate that peripheral device protocol. Upon such a reconfiguration, the peripheral protocol negotiation may “step aside”, and one or more subsequent communications between a host computer and the peripheral device utilizing the peripheral device protocol may start.

    摘要: A bidirectional multidrop processor bus is connected to a plurality of bus agents. Bus throughput can be increased by operating the bus in a multi pumped signaling mode in which multiple information elements are driven onto a bus by a driving agent at a rate that is a multiple of the frequency of the bus clock. The driving agent also activates a strobe to identify sampling points for the information elements. Information elements for a request can be driven, for example, using a double pumped signaling mode in which two information elements are driven during one bus clock cycle. Data elements for a data line transfer can be driven, for example, using a quad pumped signaling mode in which four data elements are driven during one bus clock cycle. Multiple strobe signals can be temporarily activated in an offset or staggered arrangement to reduce the frequency of the strobe signals. Sampling symmetry can be improved by using only one type of edge (e.g., either the rising edges or the falling edges) of the strobe signals to identify the sampling points.

    摘要: A bus agent that may be used in an enhanced highly pipelined bus architecture. In one embodiment, the bus agent includes a target ready interface, a set of response interfaces for a set of response signals, and a data bus busy interface, and a bus clock interface for a bus clock signal. The bus agent of this embodiment also includes bus controller logic to track a plurality of transactions comprising a transaction N-1 and a transaction N, the bus controller being capable of asserting the target ready signal for transaction N if the bus agent is asserting the data busy signal for the transaction N-1 and deasserts the data busy signal.

    摘要: A method and apparatus for tracking transactions in a pipelined bus includes a bus state tracking queue and control logic. The bus state tracking queue maintains a record of bus transaction information for each of a plurality of transactions pending on the bus. The control logic, coupled to the bus state tracking queue, updates the status of the plurality of transactions in the bus state tracking queue as the transactions progress through the pipeline.

    摘要: A clocking scheme for transferring data between electronic devices. The clocking scheme includes sending a data request signal from a first device to a second device during a first system clocking period. The second device then sends the requested data and a corresponding data validation signal to the first device. The data validation signal latches the data into the second device. The data is latched by the validation signal in a time period that is typically shorter than the clocking period of the system clock.
