Abstract: Systems and methods relate to safely and efficiently operating a multiprocessing system involving cooperation of a first processor and a second processor. For example, with regard to a first process of a first processor to be handed off to a second processor for execution, a first memory protection domain (PD) is created in a common memory, the first memory PD corresponding to the first process. The first memory PD is extended between the first processor and the second processor such that the second processor is enabled to execute the first process within the first memory PD. With regard to the first process, accesses to the common memory by the first and second processors are limited to the first memory PD, which ensures safety of the first and second processors from one another.

Abstract: Provided are exemplary apparatus and methods for transmitting an over-the-air actionable message. In an example, a mobile device includes a detector to identify an over-the-air actionable messaging command that has a destination device identifier corresponding to a second mobile device. The mobile device also includes a message converter to convert the over-the-air messaging command into the actionable message, which has a destination corresponding to the destination device identifier of the second mobile device. Further, the mobile device has a transmitter to transmit the actionable message over-the-air to the second mobile device.
