    摘要: A multicore processor comprises a plurality of cache memories, and a plurality of processor cores, each associated with one of the cache memories. Each of at least some of the cache memories is configured to maintain at least a portion of the cache memory in which each cache line is dynamically managed as either local to the associated processor core or shared among multiple processor cores.

    摘要: A multicore processor comprises a plurality of cache memories; a plurality of processor cores, each associated with one of the cache memories; one or more memory interfaces providing memory access paths from the cache memories to a main memory; and one or more directory controllers for respective portions of the main memory, each associated with corresponding storage for directory state. Each corresponding storage provides space for maintaining directory state for each memory line that is indicated as stored in at least one of the cache memories such that the space for maintaining directory state is independent of the size of the main memory.

    摘要: 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.
