A dynamic cache system is configured to flexibly respond to changes in operating parameters of a data storage and retrieval system. A cache controller in the system implements a caching policy describing how and what data should be cached. The policy can provide different caching behavior based on exemplary parameters such as a user ID, a specified application or a given workload. The cache controller is coupled to the data path for a data storage system and can be implemented as a filter in a filter framework. The cache memory for storing cached data can be local or remote from the cache controller. The policies implemented in the cache controller permit an application to control caching of data to permit optimization of data flow for the particular application.

An application framework including different application programming interfaces (APIs) is described which performs a variety of mobile device functions in response to API calls from applications. For example, in response to relatively simple API calls made by applications the application framework manages the complex tasks associated with invitations and matchmaking. By way of example, the details of complex transactions such as establishing peer-to-peer connections between mobile devices may be transparent to the application developer, thereby simplifying the application design process. The application framework may include an application daemon for communicating with a first set of services and an applications services module for communicating with a separate set of services. The application framework may also include a cache for caching data for each of the services based on different cache management policies driven by each of the services. The cache may be updated by push notification cache updates sent from each of the services.

The feature size of semiconductor devices continues to decrease in each new generation. Smaller channel lengths lead to increased leakage currents. To reduce leakage current, some power domains within a device may be powered off (e.g., power collapsed) during periods of inactivity. However, when power is returned to the collapsed domains, circuitry in other power domains may experience significant processing overhead associated with reconfiguring communication channels to the newly powered domains. Provided in the present disclosure are exemplary techniques for isolating power domains to promote flexible power collapse while better managing the processing overhead associated with reestablishing data connections.
