POLLING-DRIVEN DEVICE DRIVER INTERFACE

摘要

Embodiments of the present invention provide a storage device (SSD) system architecture including a host comprising a device driver associated with a storage device and a central processing unit (CPU). The CPU is configured to request an input or output (I/O) operation of a storage device and begin polling the storage device via the device driver to determine whether the requested operation has been completed. The CPU begins its initial polling after waiting for a time interval equal to the storage device's predicted response time to elapse.
