摘要: A method for routing data for an e-beam writer includes, with a switching device of the e-beam writer, receiving a packet. The method further includes, with a scheduling engine of the switching device, routing the packet to one of a plurality of output buffers, wherein the routing is based on availabilities of the plurality of output buffers and vacancy levels of memory devices associated with the plurality of output buffers. The method further includes, with the switching device, outputting the packet from an output port associated with a memory device to which the packet is routed.

摘要: A method includes receiving, by an input buffer of a switching device, a packet, determining, by a scheduling engine of the switching device, a destination output buffer for the packet, receiving, by the scheduling engine of the switching device, an availability of the destination output buffer and a vacancy level of a memory device that is associated with the destination output buffer, and based on the availability of the destination output buffer and the vacancy level of the memory device, determining, by the scheduling engine of the switching device, a routing destination of the packet. The routing destination includes the input buffer, the destination output buffer, and the memory device.
