A memory subsystem includes multiple different caches configured for different types of data transfer operations between one or more processing units and a main memory. The different caches can include a first general cache configured for general random memory accesses, a software controlled cache used for controlling cache operations for different processing devices accessing the same data, and a streaming cache configured for large packet data memory accesses. An arbiter may be used for arbitrating requests by the multiple different caches for accessing the main memory.

A database that can store static and dynamic entries, wherein a static entry contains conventional static data, and a dynamic entry contains information specifying dynamic behavior to control devices on a network. In this database, the act of storing a dynamic entry in the database triggers control over devices on the network. More specifically, one embodiment of a database system according to the present invention includes a data storage medium for storing entries as well as an indexing structure for locating entries on the data storage medium. It also includes a storage mechanism for performing operations to store entries on the data storage medium. Encoded on the data storage medium are dynamic entries containing descriptions of dynamic behavior for the devices on the network. The database additionally includes an execution mechanism that, in response to a dynamic entry being stored on the data storage medium, commands the devices on the network to perform the dynamic behavior specified in the dynamic entry. In a variation on the above embodiment, the execution mechanism is configured to periodically monitor and control the devices on the network.

A system and method allow client applications to invoke remote procedures on a server application using any of a plurality of remote procedure mechanisms, by selecting a remote procedure call mechanism at runtime. The system and method uses client and server stubs in the application that include an mechanism-independent canonical specification of each procedure interface. The specification defines the form of the interface and arguments, but not does include conventional mechanism-specific marshalling arguments for marshalling the arguments. The resulting compiled stubs may be used with any remote procedure call engine. Such remote procedure call engines receive the specification of the procedure interface and the arguments passed by the client application to the server, and determine at runtime the particular marshalling routines to use, according to the canonical specification. This defers selection of the marshalling routines, and hence allows a single compiled client application binary code to be used with any of a variety of remote procedure call engines and marshalling routines. Deferring selection of marshalling routines further allows optimization of data types where the client and server computers share architectural characteristics. The system includes a interface definition language compiler that produces the client and server stubs having the canonical specification of the procedure interfaces, a virtual remote procedure library that selects a remote procedure call engine for a client, and plurality of remote procedure call engines.
