Abstract: A method, device, and system with processing-in-memory (PIM)-based hash querying. A method includes, by a processing-in-memory (PIM) device, generating, corresponding to a query instruction to the PIM device from a processor exterior to the PIM device, location index indication information for a key based on a cuckoo hash table, the key, identification information of a bucket to which the key belongs, and an index vector, respectively obtained or provided from one or more devices exterior to the PIM device, and outputting the generated location index indication information for the processor to obtain the value corresponding to the key dependent on the output location index indication information, where the bucket is one of a plurality of buckets, of the cuckoo hash table, for each of which corresponding two or more keys respectively belong.

Abstract: A method and apparatus for transmitting data based on peripheral component interconnect express (PCIe) are disclosed. The method includes receiving, at an endpoint (EP), a doorbell (DB) message transmitted from a root complex (RC) via a PCIe connection between the endpoint (EP) and the RC; based on the DB message, transmitting, by polling of a processor of the EP, a read request message to a direct memory access (DMA) controller of the EP; and in response to reception of the read request message by the DMA controller, reading, by the DMA controller, data to be transmitted from a memory of the RC and recording read data into a memory of the EP.
