A computing device, comprising at least one peripheral computing component, electrically connected to each of a plurality of hardware processors; wherein at least one of the plurality of hardware processors is adapted to executing a code for: configuring the at least one peripheral computing component to access at least one first memory location in a first memory component electrically coupled with a first hardware processor of the plurality of hardware processors via a first electrical connection between the peripheral computing component and the first hardware processor; and configuring the at least one peripheral computing component to access at least one second memory location in a second memory component electrically coupled with a second hardware processor of the plurality of hardware processors via a second electrical connection between the peripheral computing component and the second hardware processor; and wherein the first hardware processor is not the second hardware processor.

Multiple processor computing device with configurable electrical connectivity to peripherals

Described herein are embodiments that adaptively reduce the number of interrupts that occur between a device controller and a computer system. Device commands are submitted to the controller by an operating system on behalf of an application. The device performs the received commands and indicates command completions to the controller. A counter counts completions, and if the count exceeds a threshold number, the controller generates an interrupt to the computer system. If the count is greater than zero and the timeout interval has expired, then the controller generates an interrupt to the computer system. In some embodiments, the application attaches flags to one of the commands indicating that an interrupt relating to completion of the flagged command should be generated as soon as possible or that an interrupt relating to completion of all commands prior to and including the flagged command should be generated as soon as possible.
