METHODS AND ARRANGEMENTS FOR A MULTISTACK BLUETOOTH CONTROLLER

摘要

Embodiments may comprise logic such as hardware and/or code to assign or offload Bluetooth applications from the main processor while maintaining the legacy interface to the OS protocol stack 5 and compatibility to legacy Bluetooth applications. Embodiments may comprise selection logic such as a multiplexer in the Bluetooth radio controller to allow it to support multiple Bluetooth core stacks. The selection logic may enable offloading specific applications to an additional stack, such as an embedded stack while supporting the operating system (OS) stack in parallel. Embodiments may also comprise a Bluetooth radio controller with one or more additional host interface drivers to 10 support multiple Bluetooth core stacks.
