MANAGING MULTIPLE SYSTEMS IN A COMPUTER DEVICE

摘要

Resources of multiple systems are managed in a computer device. A first processing system having a set of dedicated resources also has a resource manager to manage at least one of the resources. The first processing system is prevented from directly accessing the resources without authorization. A second processing system, connected to the set of dedicated resources, has a supervisor application to grant control to individual resources to the resource manager of the first processing system. A computer program is executed in the first processing system. The supervisor application grants control of at least one resource to the resource manager of the first processing system in a way that is transparently to the computer program executing in the first processing system.

1. A computer device, comprising:
a first processing system configured to execute a computer program, the first processing system having a resource manager configured to manage at least one resource and configured to deliver a program execution output via an output resource; a set of resources dedicated to the first processing system wherein the set of resources includes the output resource; and a second processing system coupled to the set of resources, the second processing system having a supervisor application configured to grant control to individual resources of the set of resources to the resource manager of the first processing system, wherein the first processing system has access to the individual resources only after the supervisor application has granted control of the individual resources, wherein control of the output resource is granted by the supervisor application to the first processing system transparently to the computer program.
