Abstract: There is disclosed a router for routing data on a computing chip comprising a plurality of processing elements, the router comprising: a packet processing pipeline; a dropped packet buffer; and one or more circuits configured to: determine that a data packet in the packet processing pipeline is to be dropped; move the data packet that is to be dropped from the packet processing pipeline to the dropped packet buffer; and re-insert the dropped data packet from the dropped packet buffer into the packet processing pipeline for re-processing.

Abstract: A method of transmitting data between a plurality of inter-connected elements. The method comprises receiving a message from a first element, said message comprising a routing key plus optionally a data payload. The routing key is processed to identify a plurality of said inter-connected elements, and data is transmitted to said identified plurality of inter-connected elements.

Abstract: A memory configuration for use in a computer system includes a plurality of address decoders each of which is allocated an identifier having a predetermined number of bits, each bit having first and second selectable states. A data memory having a plurality of word lines of predetermined length, is also included in each of the address decoders and is activatable to select one of the plurality of word lines. The address decoders receive an input address having a predetermined number of bits and compare the identifier of an address decoder with the input address wherein the memory further activates an address decoder if at least a predetermined minimum number of bits set to the first selectable state in the input address correspond to bits set to the first selectable state in the decoder identifier.
