  • Component/Virtual Dspin Array

    v1 v2  
    55== 1) Functional Description ==
    66
    7 This hardware component is a VCI compliant ring, implemented as a combinational daisy-chain and well suited for FPGA implementations.it contains two independent rings for   VCI commands and VCI responses. It is composed of an two-dimensionnal array of [wiki:Component/VirtualDspinRouter VirtualDspinRouter].
     7The Virtual Dspin Array is a two-dimensionnal array composed of [wiki:Component/VirtualDspinRouter VirtualDspinRouter], for routing paquets of two virtual channels on the same physic network.
