Abstract: A test apparatus for testing a booting and shutdown process of a computer system provided. The test apparatus includes a power control unit and a test control unit. The power control unit is for receiving AC power, and selectively outputting the AC power to a power supply end of the computer system. The test control unit outputs a power control signal to the power control unit, for controlling the power control unit to output the AC power to the power supply end.

Abstract: The present invention provides for an apparatus employed to debug a program operating in a supplemental processor when the processor's registers are not readable directly by the debugging operation of a main processor. A program operating in main memory halts due to operational errors. The program code lines save to a cache. In the main processor, a pool of memory is reserved. A copy of the data from the nominally inaccessible supplementary processor registers also transfers to the reserved storage area for processing of the program needing debugging. After the program debugging is complete, a copy of the contents of the memory pool is restored to the memory of the target supplemental processor. A copy of the local store register state and remaining local store data returns to main memory.

Abstract: A system and method are provided to allow demand loading and discarding of Java executable image (JXE) files. The virtual machine allocates an address space for a requested JXE program. The read-only portion of the JXE file is memory mapped from its nonvolatile location to the allocated memory space using read-only mapping and the read/write section of the JXE file are loaded into memory. When a page of the JXE program is needed, a page fault occurs if the read-only portion has not been loaded into memory. The operating system's page fault handler retrieves the needed page(s) from the nonvolatile storage location based upon the mapping data that resulted from the previously performed memory mapping. Because the read-only section of the JXE file is memory mapped using read-only mapping, the operating system's paging process is free to discard previously loaded memory pages that contain read-only portions of the JXE file.

Abstract: Embodiments of the present invention provide Forward Error Correcting Code encoders and decoder structures that use DRAM in their memory designs. DRAM is a very attractive memory options in many electronic systems due to the high memory density provided by DRAM. However, the DRAM is typically not included in ASIC or FPGA implementations of encoders and decoders due to complex refresh requirements of DRAM that are required to maintain data stored in DRAM and may interfere with user access to the memory space during refresh cycles. Embodiments of the present invention provide FECC encoder and decoder structures that are implemented using DRAM that do not require complex refresh operations to be performed on the DRAM to ensure data integrity. Accordingly, embodiments of the present invention maximize memory density without the added complexity of introduced by the refresh requirements of DRAM.

Abstract: In an iterative error correction method and apparatus for correcting errors in digital data read from a storage medium, re-reads are combined with the error correction procedure in a single error recovery procedure. The data read from the storage medium are represented as a multi-dimensional data structure, and the error recovery procedure is undertaken for each dimension of the data structure. In each dimension, an erasure map is generated that contains errors in the initial read of the data for that dimension, and the errors in the erasure map are deducted as they are corrected in subsequent re-reads. After a predetermined number of re-reads, or when no further errors exist, the error recovery procedure is ended.

Abstract: The present invention uses spatial dictionaries (termed locationaries), for meaningfully checking and correcting the spelling of text on Geographic Information System (GIS) maps or other computer documents containing spatially, or coordinate-, bound text. Locationaries keep track of correctly spelled words and the geographic areas within which they are considered correctly spelled.

Once all errors and suggestions are found with such an engine and within user-specified criteria, a dialog is shown that contains a row per potentially-misspelled word found. From that dialog, the user can edit the word in the original textual object of the map.
