METHOD AND SYSTEM FOR QUEUING TRANSFERS OF MULTIPLE NON-CONTIGUOUS ADDRESS RANGES WITH A SINGLE COMMAND

Title:

METHOD AND SYSTEM FOR QUEUING TRANSFERS OF MULTIPLE NON-CONTIGUOUS ADDRESS RANGES WITH A SINGLE COMMAND

Document Type and Number:

WIPO Patent Application WO/2010/074944

Kind Code:

A3

Abstract:

Methods and systems for queuing transfers of multiple non-contiguous address ranges within a single command are disclosed. Embodiments of systems include system processors, memory to store data and executable software, and storage devices to receive transfer commands stored in system memory. A host controller interface driver is executed by one or more system processors and collects multiple non-continuous address ranges from storage-device transfer requests and records starting addresses and quantities of data to transfer for each non-continuous range in a tagged command list. It records the number of address ranges in the tagged command list, and a tagged-transfer opcode in a command, and stores the command and the tagged command list in a command table for the storage device. It records a base address for the command table in memory and an offset for the tagged command list into a command header, which is stored in a command queue.
