Accelerated computation of direct memory access scatter context for get response

A network device, comprising:

• at least one processing resource;
• and
• a storage device storing instructions which when executed by the at least one processing resource comprise instructions to:
• receive an instruction corresponding to a Get request packet of a message, wherein the instruction indicates a type of pattern associated with direct memory access (DMA) write operations;
• determine a descriptor and a starting context associated with the Get request packet in response to the type of pattern indicating nested loops associated with a multi-dimensional array structure, wherein the descriptor defines a direct memory access (DMA) scatter operation based on the nested loops;
• provide access to the starting context in response to processing a Get response packet corresponding to the Get request packet by storing the starting context in a hardware table;
• process the instruction in cycles until a byte count is equal to or greater than a size of a payload associated with the Get request packet,
• wherein the byte count comprises a number of bytes hypothetically transferred while processing the instruction and wherein processing the instruction in cycles comprises updating loop counters and a byte offset associated with iterating through the nested loops;
• obtain, based on the processed instruction, an ending context comprising the updated loop counters and byte offset;
• and
• store the ending context in a cache as the starting context for a next instruction of a same message.

A non-transitory computer-readable medium storing instructions to:

• receive an instruction corresponding to a Get request packet of a message, the instruction indicating a type of pattern associated with direct memory access (DMA) write operations;
• determine a descriptor and a starting context associated with the Get request packet in response to the type of pattern indicating nested loops associated with a multi-dimensional array structure, the descriptor defining a direct memory access (DMA) scatter operation based on the nested loops;
• provide access to the starting context in response to processing a Get response packet corresponding to the Get request packet by storing the starting context in a hardware table;
• process the instruction in cycles until a byte count is equal to or greater than a size of a payload associated with the Get request packet, the byte count comprising a number of bytes hypothetically transferred while processing the instruction, and processing the instruction in cycles comprising updating loop counters and a byte offset associated with iterating through the nested loops;
• obtain, based on the processed instruction, an ending context comprising the updated loop counters and byte offset;
• and
• store the ending context in a cache as the starting context for a next instruction of a same message.
