  • PERIPHERAL DEVICE WITH HARDWARE LINKED LIST
    Publication number: 20060253694
    Abstract: A linked list is implemented in hardware. Various registers within the linked list are writeable until a control register is written, rendering the registers read-only. A computer peripheral includes the hardware linked list to provide a list of capabilities to a querying device. The linked list can be built, modified, or disabled by low level software, and then locked so that it appears as read-only to higher level software such as an operating system or device driver.
