Abstract
In an embodiment, a multi-processor mobile communications device includes a first processor system executing a concurrency manager server application (CMSA) and a second processor system executing a concurrency manager client application (CMCA). The CMSA determines priority levels related to access to resources for a first set of applications that are configured for execution on the first processor system and a second set of applications that are configured for execution on the second processor system. The CMSA notifies the CMCA of the determined priorities. The CMSA and the CMCA each then selectively grant or reject access to the resources for the first and second sets of applications, respectively, based on the determined priorities levels. In another embodiment, if the CMSA or CMCA rejects an application's request to access resources, the CMSA or CMCA can determine availability of alternative resources by which the requesting application can achieve its goal.
