Near memory processing device, processor and data processing method

A data processing method executed in a near memory processing device, comprising:

• receiving, from a processor external to the near memory processing device, an indirect block parse request and a checksum update request, determining an address of a first target data block from a memory based on the indirect block parse request, and calculating a checksum of a second target data block and writing the calculated checksum to the memory based on the checksum update request;
• receiving, from the processor, a deduplication table query request, and performing deduplication table search processing based on the deduplication table query request to determine whether a third target data block exists in the memory;
• and
• receiving, from the processor, a range tree query request, and traversing a range tree in the memory based on the range tree query request to determine a target node corresponding to the range tree query request.

A host system comprising:

• a processor;
• and
• a near memory processing device,
• wherein the processor is configured to:
• generate an indirect block parse request based on an instruction to read or write a first target data block, and transmit the indirect block parse request to a near memory processing device,
• generate a checksum update request based on an instruction to write a second target data block, and transmit the checksum update request to the near memory processing device,
• generate a deduplication table query request based on an instruction to read or write a third target data block, and transmit the deduplication table query request to the near memory processing device, and
• generate a range tree query request based on an instruction to read or write data, and transmit the range tree query request to the near memory processing device, and wherein the near memory processing device comprising:
• a memory, and
• a calculation core comprising:
• a block trace core configured to receive, from the processor external to the near memory processing device, the indirect block parse request and the checksum update request, determine an address of a first target data block from the memory based on the indirect block parse request, and calculate a checksum of a second target data block and write the calculated checksum to the memory based on the checksum update request,
• a deduplication table search core configured to receive, from the processor, the deduplication table query request, and perform deduplication table search processing based on the deduplication table query request to determine whether a third target data block exists in the memory, and
• a tree traverse core configured to receive, from the processor, the range tree query request, and traverse a range tree in the memory based on the range tree query request to determine a target node corresponding to the range tree query request.
