Queue management for direct memory access

A system for managing a plurality of queues, the system comprising:

• at least one processor;
• and
• at least one memory in communication with the at least one processor, the at least one memory having computer readable instructions stored thereupon that, when executed by the at least one processor, cause the at least one processor to:
• determine a data block is ready for transfer based on a descriptor in a first queue, the descriptor including a first dimension of the data block and a second dimension of the data block, each of the first and second dimensions being individual byte values;
• analyze the descriptor in the first queue to determine a dimension of the data block based on at least one of the first and second dimensions included in the descriptor;
• and
• compare the dimension of the data block to a data threshold, the data threshold having been dynamically determined:
• when the dimension of the data block is greater than the data threshold, fragment the data block to generate at least a plurality of fragmented data blocks from the data block and send at least one of the plurality of fragmented data blocks to a destination memory location,
• determine a second data block, identified by an operation descriptor in a second queue, is ready for transfer, and
• send at least a portion of the second data block identified by the operation descriptor to a memory location after the at least one of the plurality of fragmented data blocks is sent to the destination memory location, and
• when the dimension of the data block is less than the data threshold, send the data block to the destination memory location unfragmented.

A computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by one or more processors of a computing device, cause the one or more processors of the computing device to:

• determine a data block is ready for transfer based on a descriptor in a first queue, the descriptor including a first dimension of the data block and a second dimension of the data block, each of the first and second dimensions being individual byte values;
• analyze the descriptor in the first queue to determine a dimension of the data block based on at least one of the first and second dimensions included in the descriptor;
• and
• compare the dimension of the data block to a data threshold:
• when the dimension of the data block is greater than the data threshold, fragment the data block to generate at least a plurality of fragmented data blocks from the data block and send at least one of the plurality of fragmented data blocks to a destination memory location, and
• when the dimension of the data block is less than the data threshold, send the data block to the destination memory location unfragmented.
