  • Patent number: 9323708
    Abstract: A computing and communication architecture utilizes a serial protocol based switched fabric among circuit cards housed in packaging arrangement. In one embodiment, each circuit card connected to the serial protocol based switched fabric in the packaging arrangement is provided with a protocol processor that enables all of the circuit cards to efficiently provide packet-based serial self-clocked communications at line speed. As a result, it is not necessary to arrange the circuit cards in a hierarchical manner in order to address the problems of switch blocking and related traffic congestion issues that would otherwise limit the implementation of the serial protocol based backplane arrangement for housing circuit cards.

  • Patent number: 8234483
    Abstract: A computing and communication chip architecture is provided wherein the interfaces of processor access to the memory chips are implemented as a high-speed packet switched serial interface as part of each chip. In one embodiment, the interface is accomplished through a gigabit Ethernet interface provided by protocol processor integrated as part of the chip. The protocol processor encapsulates the memory address and control information like Read, Write, number of successive bytes etc, as an Ethernet packet for communication among the processor and memory chips that are located on the same motherboard, or even on different circuit cards. In one embodiment, the communication over head of the Ethernet protocol is further reduced by using an enhanced Ethernet protocol with shortened data frames within a constrained neighborhood, and/or by utilizing a bit stream switch where direct connection paths can be established between elements that comprise the computing or communication architecture.
