摘要:
A priority register is provided for each of a multiple processor cores of a chip multiprocessor, where the priority register stores values that are used to bias resources available to the multiple processor cores. Even though such multiple processor cores have their own local resources, they must compete for shared resources. These shared resources may be stored on the chip or off the chip. The priority register biases the arbitration process that arbitrates access to or ongoing use of the shared resources based on the values stored in the priority registers. The way it accomplishes such biasing is by tagging operations issued from the multiple processor cores with the priority values, and then comparing the values within each arbiter of the shared resources.
摘要:
A run-time executive of an object management system for managing execution of software components in an object execution environment uses a component context object to store intrinsic context properties related to an associated component. The run-time executive maintains an implicit association of the component context object with the application component. For example, the context properties can include a client id, an activity id, and a transaction reference. The component context object also provides an interface accessible to the associated component, with member functions for use in transaction processing, in creating additional other application components inheriting component's context properties, and in access control based on abstract user classes (roles).
