  • Mechanism for self refresh during advanced configuration and power interface (ACPI) standard C0 power state
    Patent number: 7613941
    Abstract: An embodiment may be an apparatus comprising a link coupled with a memory, and circuitry coupled with the link to calculate the amount of memory access idle time, determine if memory access idle time is sufficient to change to a self-refresh state, and change to a self-refresh state based on memory access idle time without explicit notification from a processor regarding the processor power state. Another embodiment may be a method for memory to enter self-refresh comprising calculating the amount of memory access idle time, determining if memory access idle time is sufficient to change to a self-refresh state, and changing to a self-refresh state based on memory access idle time without explicit notification from a processor regarding the processor power state. Various other embodiments systems, methods, machine readable mediums and apparatuses may provide similar functionality to these exemplary embodiments.

  • Method and apparatus for high throughput multiplexing of data
    Patent number: 6822976
    Abstract: A method and apparatus for high throughput multiplexing of data is described. It includes a circuit including: A first multiplexer having an output, a first input, a second input, and a selector. A second multiplexer having an output, a first input, a second input, and a selector, the output of the second multiplexer coupled to the first input of the first multiplexer. A third multiplexer having an output, a first input, a second input, and a selector, the output of the third multiplexer coupled to the second input of the first multiplexer; and the selector of the first multiplexer to select an input with a stable signal.
