System and method for multiengine operation with super descriptor in SAS/SATA controller wherein portion of super-descriptor is executed without intervention of initiator

摘要

A method of chaining a plurality of engines for a system on chip (SOC) controller device and a SOC controller device are disclosed herein. The method comprises: generating, at an initiator, a super-descriptor for providing instructions to the plurality of engines of the SOC controller; passing the super-descriptor from the initiator to a first engine of the plurality of engines; and executing a portion of the super-descriptor at each of the plurality of engines in series without the intervention of the initiator.
