Abstract
An apparatus to facilitate source synchronous signaling is disclosed. The apparatus includes transfer protocol logic to provide for source synchronous transfer of data within an interconnect fabric, including one or more synchronizers having logic to a transmit data signal and a source clock (clk) signal during the transfer of data.
Claims20
An apparatus comprising:
- an interconnect fabric including:
- a plurality of network interfaces for connection of the interconnect fabric to a plurality of nodes, each network interface including a set of one or more synchronizers, and
- a plurality of network switches to route data transfers between the plurality of network interfaces;
- wherein the interconnect fabric is to provide transfer of data through the interconnect fabric between a plurality of nodes connected to the plurality of network interfaces, the plurality of nodes including a plurality of compute nodes and a global shared memory for the plurality of compute nodes, wherein:
- a first network interface of the plurality of network interfaces is to receive a transmission via the interconnect fabric, wherein the transmission includes a data signal to a first node of the plurality of nodes from a second node of the plurality of nodes, and
- the first network interface is to sample and filter the data signal based on the transmission.
