  • Host-daughtercard configuration with double data rate bus
    Patent number: 8281049
    Abstract: A double data rate bus system includes a host-network interface card configuration wherein the host is configured to recognize the network interface card to establish a double data rate bus between the host and the network interface card. The host is configured to generate a plurality of generic data frame queues. Each of the generic data frame queues is configured to receive and to transmit generic data frames via the double data rate bus. The network interface card is configured to transmit a plurality of dynamic memory access read requests to the host via the double data rate bus. The host is configured to allow each of the plurality of dynamic memory access read requests to remain pending prior to responding to any one of the plurality of dynamic memory access read requests.

  • Backward-compatible parallel DDR bus for use in host-daughtercard interface
    Patent number: 7181551
    Abstract: A host-daughtercard interface is pin compatible with a legacy interface but redefines a subset of pins to implement a high-bandwidth double data-rate (DDR) bus. By inspecting a cookie on the daughtercard, the host platform determines whether the daughtercard supports the DDR bus or the legacy interface, and then configures the subset of pins to implement the legacy interface or the DDR bus.
