Abstract:
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.
