摘要： A disk drive is disclosed comprising a first disk surface comprising a plurality of tracks, wherein each track comprises a number of data sectors and a number of servo sectors, and a second disk surface comprising a plurality of tracks, wherein each track comprises a number of data sectors and a number of servo sectors. A first repeatable runout (RRO) sinusoid is generated representing an RRO of the first disk surface, and a second RRO sinusoid is generated representing an RRO of the second disk surface. A plurality of access commands are received from a host which are stored in a command queue, and one of the access commands is selected to execute in response to the first and second RRO sinusoids.

摘要： Embodiments of the invention are directed to systems and methods for reducing the number of interrupts on a controller for a non-volatile storage device to improve data transfer performance of the storage system. The embodiments described herein selectively enable an interrupt generated by host transfer hardware for a host command. The interrupt can be enabled or disabled by considering the command type, availability of interface resources to accept additional host transfers, and the command size. Embodiments described herein are useful for host interfaces implementing a tagging scheme for host transfers with a limited range of identification tags.

摘要： Controlling a buffered data transfer between a source and a destination by loading a source count value and a destination count value from a buffered data transfer device. A source delta value is computed by subtracting a source previous value from the source count value. The destination count value is adjusted on the buffered data transfer device by adding the source delta value to the destination count value. A destination delta value is computed by subtracting a destination previous value from the destination count value. The source count value is adjusted on the buffered data transfer device by adding the destination delta value to the source count value. A new value for the source previous value is computed by adding the source count value and the destination delta value. A new value for the destination previous value is computed by adding the destination count value and the source delta value.
