    Abstract: A method for monitoring a heap in real-time to assess the performance of a virtual machine. A mobile agent is created to be preloaded with boundary settings for each heap metric. Boundary settings are thresholds that are used to diagnose the effectiveness of operation of the heap. The mobile agent is deployed onto an application server to monitor the effectiveness of operation of the heap of a virtual machine within the application server. If a boundary setting for one of the heap metrics is exceeded, then the mobile agent determines whether a non-critical, a critical or a fatal error has occurred. An appropriate response is then performed. By monitoring the heap in real-time, undesirable behavior characteristics of the heap can be detected early thereby allowing remedial actions to be enacted to address such problems before those problems escalate into more serious problems.

  • Publication number: 20120278665
    Abstract: Detecting a fault in the operation of a computer having a processor and a memory is taught. Instrumentation code is placed within an application program during compilation, and runtime library routines are modified to support detection of invalid memory accesses. Memory space is divided into application, shadow and unmapped memories. When accessing application memory at an original address, an address in shadow memory is computed by shifting the address and adding an offset. If the value stored at the shadow address indicates that the original address is invalid (e.g., not allocated or already freed), then error reporting code is executed that indicates the type of error and the location and optionally halts the computer. Invalid memory references to heap, stack and global objects in application memory can be detected.

    Abstract: Each of (n?1) 2-bit checking units, where n is an integer larger than or equal to 4, receives n-bit redundant encoded data generated from 1-bit input data, and outputs 2-bit check data based on a result of comparison between bits of the encoded data, combinations of the bits differing in each comparison. An all-bit checking unit outputs all-bit check data based on exclusive ORs of all-bit of the encoded data. An error detecting unit detects errors in the encoded data on the basis of the (n?1) sets of 2-bit check data and the all-bit check data, and outputs the input data on the basis of the result of error detection.

  • Publication number: 20120278667
    Abstract: A media player may occasionally be unable to play or continue to play a particular item of media. When that occurs, the media player outputs an error indication that is related to the type of media that the problem media item is representative of. For example, if the problem item is a movie, then the media player may display an error indication having the appearance of broken movie film. If the problem media item is music, then the media player may display an error indication having the appearance of a broken compact disc (“CD”). Thus whatever the type of media that is not playing, the media player outputs an error indication that is appropriate for that type of media. The error indications output by the player are therefore context-based or media-appropriate.

  • Publication number: 20120272120
    Abstract: Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. For acceptable quality assurance, conventional error correction codes (“ECC”) have to correct a maximum number of error bits up to the far tail end of a statistical population. The present memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. If excessive error bits (at the far tail-end) occur after writing a group of data to the second portion, the data is adaptively rewritten to the first portion which will produce less error bits. Preferably, the data is initially written to a cache also in the first portion to provide source data for any rewrites. Thus, a more efficient ECC not requiring to correcting for the far tail end can be used.

    Abstract: A performance monitoring technique provides task-switch immune operation without requiring storage and retrieval of the performance monitor state when a task switch occurs and provides accurate performance monitoring information. When a hypervisor signals that a task is being resumed and the application privilege level has been entered, it provides an indication, which starts a delay timer. The delay timer is resettable in case a predetermined time period has not elapsed when the next task switch occurs. After the delay timer expires, analysis of the performance monitor measurements is resumed, which prevents an initial state, a state due to execution of the operating system or hypervisor, or a state remaining from a previous task from corrupting the performance monitoring results. The performance monitor may be or include an execution trace unit that collects branch information in a current program execution trace.

    Abstract: A system implementing parallel memory error detection and correction divides data having a word length of K bits into multiple N-bit portions. The system has a separate error processing subsystem for each of the N-bit portions, and utilizes each error processing subsystem to process the associated N-bit portion of the K-bit input data. During memory write operations, each error processing subsystem generates parity information for the N-bit data, and writes the N-bit data and parity information into a separate memory array that corresponds to the error processing subsystem. During memory read operations, each error processing subsystem reads N-bits of data and the associated parity information. If, based on the parity information, an error is detected from the N-bit data, the error processing subsystem attempts to correct the error. The corrected N-bit data from each of the error processing subsystems are combined to reproduce the K-bit word.

    Abstract: A memory device (e.g., a flash memory device) includes power efficient codeword error analysis circuitry. The circuitry analyzes codewords stored in the memory of the memory device to locate and correct errors in the codewords before the codewords are communicated to a host device that requests the codewords from the memory device. The circuitry includes a highly parallel configuration with reduced complexity (e.g., reduced gate count) that a controller may cause to perform the error analysis under most circumstances. The circuitry also includes an analysis section of greater complexity with a less parallel configuration that the controller may cause to perform the error analysis less frequently. Because the more complex analysis section runs less frequently, the error analysis circuitry may provide significant power consumption savings in comparison to prior designs for error analysis circuitry.

    Abstract: The described embodiments provide a processor that executes vector instructions. In the described embodiments, the processor initializes an architectural fault-status register (FSR) and a shadow copy of the architectural FSR by setting each of N bit positions in the architectural FSR and the shadow copy of the architectural FSR to a first predetermined value. The processor then executes a first first-faulting or non-faulting (FF/NF) vector instruction. While executing the first vector instruction, the processor also executes one or more subsequent FF/NF instructions. In these embodiments, when executing the first vector instruction and the subsequent vector instructions, the processor updates one or more bit positions in the shadow copy of the architectural FSR to a second predetermined value upon encountering a fault condition.
