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.
摘要:
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.
