ABSTRACT:
A hardware accelerated memory system in a hardware accelerated I/O data processing engine that gathers and maintains pointers to a set of widely distributed source and/or destination data locations. The locations of the source and/or destination data locations operated on by the I/O data processing engine can include a memory local to the command interpreter and a memory remote from but accessible to the command interpreter by way of an I/O bus. Each source and/or destination scatter/gather list contains pointers to actual data locations that are either in a memory local to the command interpreter or a memory remote from the command interpreter but accessible by way of an interconnecting I/O bus. Each data location entry in a scatter/gather list is also accompanied by a byte count indicative of the total number of bytes at a given data location.
