Abstract: An integrated circuit comprises a plurality of tiles. Each tile comprises: a processor, a switch including switching circuitry to forward data received over data paths from other tiles to the processor and to switches of other tiles, and to forward data received from the processor to switches of other tiles, according to a switch instruction indicating an input port to which each of multiple output ports of the switch is to be coupled, and a translation lookaside buffer coupled to the switch to translate virtual memory addresses of switch instructions to physical memory addresses of the switch instructions.

Abstract: An integrated circuit comprises a plurality of tiles. Each tile comprises a processor, and a switch including switching circuitry to forward data received over data paths from other tiles to the processor and to switches of other tiles, and to forward data received from the processor to switches of other tiles. The integrated circuit further includes a plurality of memory interface modules including circuitry to access a respective external memory, each memory interface module coupled to a switch of at least one tile. At least some of the tiles are configured to access an address in an external memory by sending from the switch a packet that includes a physical memory address that includes the external memory address and information identifying the corresponding external memory.

Abstract: An integrated circuit comprises a plurality of tiles. Each tile comprises a processor including a storage module, wherein the processor is configured to process multiple streams of instructions, a switch including switching circuitry to forward data received over data paths from other tiles to the processor and to switches of other tiles, and to forward data received from the processor to switches of other tiles, and coupling circuitry configured to couple data resulting from processing an instruction from at least one of the streams of instructions to the storage module and to the switch.

Abstract: An integrated circuit comprises a plurality of tiles. Each tile comprises a processor, and a switch including switching circuitry to forward data received over data paths from other tiles to the processor and to switches of other tiles, and to forward data received from the processor to switches of other tiles. The integrated circuit further comprises an interface coupled to a plurality of the tiles to transfer data between one or more switches of the tiles and one or more switches of tiles in an externally coupled integrated circuit.

Abstract: Managing memory includes: mediating access to a first memory as a cache for a second memory; and associating one of a plurality of entry types with entries in the cache. Data from the second memory associated with a first type is not allowed to evict a cache entry associated with a second type.

Abstract: An integrated circuit includes a plurality of tiles. Each tile comprises a processor; and a switch including switching circuitry to forward data over data paths from other tiles to the processor and to switches of other tiles according to a switch instruction indicating an input port to which each of multiple output ports of the switch is to be coupled. The switch is able to operate in a first mode in which successive input data arriving at the switch are forwarded according to a different switch instruction, and a second mode in which successive input data arriving at the switch are forwarded according to the same switch instruction.
