Patent number: 7930576Abstract: System and method for sharing a device, e.g., non-volatile memory, between a host processor and a microcontroller. In response to system state change to a first state wherein the microcontroller is assured safe access to the non-volatile memory (e.g., in response to power-on reset, system reset, sleep state, etc.), the microcontroller holds the system in the first state (e.g., system reset), and switches access to the non-volatile memory from the processor to the microcontroller. While the system is held in the first state, the microcontroller accesses the device (e.g., non-volatile memory), e.g., fetches program instructions/data from the non-volatile memory and loads the program instructions/data into a memory of the microcontroller. After the access, the microcontroller changes or allows change of the system state, e.g., switches access to the device, e.g., the non-volatile memory, from the microcontroller to the processor, and releases the system from the first state.Type: GrantFiled: December 18, 2007Date of Patent: April 19, 2011Assignee: Standard Microsystems CorporationInventors: Ian F.

Patent number: 7685450Abstract: A system and method for monitoring usage of peripheral devices and placing a second peripheral device in a low power state when the usage indicates that a second peripheral device is not being used. For example, if a computer system detects that a user's current typing rate indicates the user probably has both hands on a keyboard, the computer system may generate a signal to the computer mouse to enter a low power state. The computer system may use prior usage for a user to determine when current usage indicates that the second peripheral device is not being used. After the second peripheral device is placed in a low power state, the computer system may generate a signal to the second peripheral device to return to a normal power state when the computer system determines that the user no longer has both hands occupied.Type: GrantFiled: February 13, 2007Date of Patent: March 23, 2010Assignee: Standard Microsystems CorporationInventors: Drew J.
