A method and apparatus for implementation of error correction code (ECC) checking in non-ECC-compliant components. The method includes receiving a logical address, wherein the logical address maps to first and second physical addresses of a memory. The first and second physical addresses of the memory correspond to memory locations that store data and a corresponding ECC, respectively. The method further comprises translating the logical address into the first and second physical addresses, accessing the data over a data path, separately accessing the ECC over the same data path, and checking the integrity of the data using the ECC.

A portable computer system including wireless communication functionality and global geographic positioning functionality includes a processor coupled to a wireless module, and a global positioning unit coupled to the wireless module and the processor. The wireless module may communicate with a wireless network via a wireless connection. The global positioning unit may be configured to receive geographic location information and to determine a current geographic location of the portable computer system based upon the received geographic location information. The processor may execute system software that may be configured to reconfigure system configuration settings such as security and authentication settings, and system clock settings, for example, dependent upon changes in the current geographic location information. In addition, an authenticated administrative level user may send one or more commands to the wireless module. The commands may cause a system storage to be made unreadable.

An apparatus including a system bus coupled to an I/O interface which includes a pointer register and a rejecting circuit which determines whether a write to the pointer register will be accepted or rejected. The I/O interface is further coupled to at least one I/O bus having at least one I/O device connected thereto. The system bus is further coupled to a main memory and to a Central Processing Unit (CPU) which is capable of executing software instructions, providing a command structure corresponding to an access of an I/O device, and writing to the pointer register an address of a location in main memory of the command structure. The CPU further includes a hardware indicator responsive to the rejecting circuit for providing a status signal indicating the status of a write to the pointer register. The CPU executes the software in accordance with the status signal. The apparatus allows the software being executed by the CPU to software pend accesses to devices not directly connected to the system bus. This improves system performance over non-pended system buses and reduces the amount of hardware needed as compared to pended system buses.

For efficiently handling data transactions between various system units (CPUs, I/O units and main memory units) in a multi-processor system, the system units are linked via a plurality of expandable crossbar modules, each providing a set of interconnections or well-defined mappings between the sets of input and output nodes, with each output being defined in terms of only one input. In addition to the nodes provided at the input and output sections, each crossbar module is also provided with discrete input and output expansion portions through which the module may be linked to other identically configured crossbar modules when additional nodes are to be integrated into the system. The expansion ports allow serial linking of crossbar modules so as to establish a connection between source and destination nodes which are spread across different crossbar modules. The serially-linked expansion ports realize direct mapping between all system nodes in the form of a two-stage network; the basic crossbar design remains the same and there is no need for the problematic redesign of crossbar modules for accommodating added data transfer nodes. The modular crossbar design is particularly adapted for use with different system configurations having different numbers of communication nodes and permits a system to be upgraded by adding communication nodes by using additional identically configured crossbar modules.

Systems and methods for mapping natural input devices to legacy system inputs are disclosed. One example system may include a computing device having an algorithmic preprocessing module configured to receive input data containing a natural user input and to identify the natural user input in the input data. The computing device may further include a gesture module coupled to the algorithmic preprocessing module, the gesture module being configured to associate the natural user input to a gesture in a gesture library. The computing device may also include a mapping module to map the gesture to a legacy controller input, and to send the legacy controller input to a legacy system in response to the natural user input.

A method and apparatus for optimizing the performance of a multibus data processing system is provided. An I/O controller is coupled to the I/O bus and includes MORE bit setting means for initiating a MORE stream transaction on the I/O bus and for thereafter terminating the MORE stream transaction. An adapter coupling the I/O bus to the system bus, is configured to receive the MORE stream transaction and transfer it to main memory. The adapter includes MORE bit decoding means for identifying the beginning and the end of the MORE stream transaction, and for identifying whether the MORE stream transaction is a READ or WRITE transaction. The adapter also includes a first buffer for receiving data from the I/O bus and transferring the data to the memory in accordance with the memory's full block transfer size, and a second buffer for receiving a full block of data and transferring that data in accordance with the I/O bus transaction limitations. The adapter is capable of invalidating data located in the first buffer and clearing data located in the second buffer in accordance with a discard transaction when the I/O controller fails to properly terminate the MORE stream transaction.
