Latest Patents

One of McIlvain's latest patents is titled "System for accessing an input/output device using multiple addresses." This invention discloses a system that performs input/output operations with a processing unit. The processing unit determines a base and associated alias addresses to address an I/O device, such as a direct access storage device (DASD). The association of these addresses is maintained constant for subsequent I/O operations until a reassignment is detected. This allows for the concurrent execution of multiple I/O operations against the I/O device using the established addresses.

Another significant patent is "Logical positioning within a storage device by a storage controller." This mechanism enables a storage controller to determine which logical position in a storage device is to be accessed next. The logical positioning mechanism includes logical position indicators that are defined, maintained, and controlled by the storage controller. These indicators help in managing the access to logical positions effectively.
