Abstract
A hardware support system for implementing accelerated disk I/O for a computer system. The system includes a bus interface for interfacing with a processor and a system memory of the computer system, a disk I/O engine coupled to the bus interface, and a device interface coupled to the disk I/O engine for interfacing the disk I/O engine with a disk drive. The disk I/O engine is configured to cause a start up of the disk drive upon receiving a disk start up command from the processor. The disk I/O engine is further configured to execute a disk transaction by processing the disk transaction information from a bypass register coupled to the disk I/O engine.
Claims6
A disk controller for implementing efficient disk I/O for a computer system, comprising:
- a bus interface for interfacing with a processor and a system memory of the computer system;
- a disk I/O engine coupled to the bus interface;
- a device interface coupled to the disk I/O engine for interfacing the disk I/O engine with a disk drive, wherein the disk I/O engine is configured to cause a start up of the disk drive upon receiving a disk start up command from the processor, the disk I/O engine further configured to execute a disk transaction by processing the disk transaction information from a bypass register coupled to the disk I/O engine;
- and
- a completion status register coupled to the disk I/O engine configured to notify the disk I/O engine and indicate a completion of a pending disk I/O command.
A bridge component for implementing efficient disk I/O for a computer system, comprising:
- a bus interface for interfacing with a processor and a system memory of the computer system;
- a disk controller for executing disk I/O transactions for the computer system, the disk controller further comprising:
- a disk I/O engine coupled to the bus interface;
- a device interface coupled to the disk I/O engine for interfacing the disk I/O engine with a disk drive, wherein the disk I/O engine is configured to cause a start up of the disk drive upon receiving a disk start up command from the processor, the disk I/O engine further configured to execute a disk transaction by processing the disk transaction information from a bypass register coupled to the disk I/O engine;
- and
- a completion status register coupled to the disk I/O engine configured to notify the disk I/O engine and indicate a completion of a pending disk I/O command.
