An intelligent home automation system answers questions of a user speaking “natural language” located in a home. The system is connected to, and may carry out the user's commands to control, any circuit, object, or system in the home. The system can answer questions by accessing the Internet. Using a transducer that “hears” human pulses, the system may be able to identify, announce and keep track of anyone entering or staying in the home or participating in a conversation, including announcing their identity in advance. The system may interrupt a conversation to implement specific commands and resume the conversation after implementation. The system may have extensible memory structures for term, phrase, relation and knowledge, question answering routines and a parser analyzer that uses transformational grammar and a modified three hypothesis analysis. The parser analyzer can be dormant unless spoken to. The system has emergency modes for prioritization of commands.

The invention relates to a device, system, and method for expanding the memory capacity of a memory module. A control unit and memory bank switch are mounted on a memory module to selectively control write and/or read operations to/from memory devices communicatively coupled to the memory bank switch. By selectively routing data to and from the memory devices, a plurality of memory devices may appear as a single memory device to the operating system. That is, the invention expands the addressable memory banks on a module by making two smaller-capacity memory devices emulate a single higher-capacity memory device.

A database system providing methodology for extended memory support is described. In one embodiment, for example, a method is described for extended memory support in a database system having a primary cache, the method comprises steps of: creating a secondary cache in memory available to the database system; mapping a virtual address range to at least a portion of the secondary cache; when the primary cache is full, replacing pages from the primary cache using the secondary cache; in response to a request for a particular page, searching for the particular page in the secondary cache if the particular page is not found in the primary cache; if the particular page is found in the secondary cache, determining a virtual address in the secondary cache where the particular page resides based on the mapping; and swapping the particular page found in the secondary cache with a page in the primary cache, so as to replace a page in the primary cache with the particular page from the secondary cache.

The decreasing cost of communication has led to a focus on including workgroup participants based on their abilities rather than their physical location. However, collaboration workgroup participants are still dependent on electronic documents which are difficult or impossible to view on smaller web-enabled devices such as web-enabled phones, web-enabled personal digital assistants and the like. If the documents can be viewed at all, they must be pre-encoded for a single format supported across all devices, or the range of participating devices must be limited to a single display type. Furthermore, some document types may require hardware upgrades including expanded memory to load the additional code necessary to view the document. This excludes impromptu workgroup formation since the device types of the collaborating users and/or the set of required documents for a meeting cannot always be predicted. Moreover, even when a document has been previously encoded, collaboration is difficult due to the inability to view the overall structure of the page. Accordingly the techniques presented allow for impromptu access to documents in the native application format. The collaboration of users within a document is facilitated by allowing the users to indicate context within the document for collaboration based on the display capabilities of each user's device.

Described is a system and method whereby processes may have multiple memory maps associated therewith to provide curtained memory and overcome other memory-related problems. Multiple maps are used to restrict memory access of existing code such as drivers, without changing that code, and without changing existing microprocessors. A thread of a process is associated with one memory map at a time, which by mapping to different memory locations, provides memory isolation without requiring a process switch. Memory isolation may be combined with controlled, closed memory map switching performed only by trusted code, to ensure that some protected memory is inaccessible to all but the trusted code (curtained memory). Map switching among multiple maps eliminates the need to change a process in order to access different memory, thereby allowing expanded memory addressing in a single process and isolating untrusted code run in process from certain memory of that process.

Memory system operations are extended for a data processor by DMA, cache, or memory controller to include a DMA descriptor, including a set of operations and parameters for the operations, which provides for data compression and decompression during or in conjunction with processes for moving data between memory elements of the memory system. The set of operations can be configured to use the parameters and perform the operations of the DMA, cache, or memory controller. The DMA, cache, or memory controller can support moves between memory having a first access latency, such as memory integrated on the same chip as a processor core, and memory having a second access latency that is longer than the first access latency, such as memory on a different integrated circuit than the processor core.

A method is disclosed for communicating using a device having a Palm OS. SMB is preferentially used to communicate with a node, and if use of SMB is not possible, FTP is used, and if use of FTP is not possible, Bluetooth is used. If FTP or Bluetooth is selected as the protocol, file sharing between the device and node that entails a read or write is executed by temporarily copying a file to an internal Palm OS memory of the device, performing the read or write on the file, and then copying the file back to the node to overwrite a previous version of the file at the node. For non-Palm OS file transfer to the internal memory, the file is wrapped in a Palm OS stream in the internal memory for executing reads or writes. For file transfer to an expansion Palm OS memory card, byte-to-byte copying of the file is executed using the FAT of the expansion memory, with the file being transferred through an internal Palm OS memory of the device.

Memory system operations are extended for a data processor by an application programming interface API, including a set of operations and parameters for the operations, which provides for data compression and decompression during or in conjunction with processes for moving data between memory elements of the memory system. The set of operations can be configured to use the parameters and perform the operations of the API. The API can support moves between memory having a first access latency, such as memory integrated on the same chip as a processor core, and memory having a second access latency that is longer than the first access latency, such as memory on a different integrated circuit than the processor core.

A computer system having a kernel for mapping virtual memory address space to physical memory address space. The computer system uses a method for performing an input/output operation. A physical memory buffer is registered with a subsystem, and the physical memory buffer is associated with a first virtual address, a size and a key. The physical memory buffer is dynamically associated with a second virtual address which is different from the first virtual address. As part of an application program an input/output operation is requested regarding the second virtual address. An application table is used to obtain the first virtual address, the key and the size. The first virtual address, the key and the size are supplied to the subsystem. The subsystem uses the first virtual address, the key and the size, to determine the physical memory buffer and performs an input/output operation using the physical memory buffer without intervention of the kernel.
