In computer programming, a logic error is a bug in a program that causes it to operate incorrectly, but not to terminate abnormally (or crash). A logic error produces unintended or undesired output or other behaviour, although it may not immediately be recognized as such.
Processor including hybrid redundancy for logic error protection
InactiveUS20090183035A1Digital computer detailsRedundant operation error correctionFloating-point unitExecution unit
A processor core includes an instruction decode unit that may dispatch a same integer instruction stream to a plurality of integer execution units and may consecutively dispatch a same floating-point instruction stream to a floating-point unit. The integer execution units may operate in lock-step such that during each clock cycle, each respective integer execution unit executes the same integer instruction. The floating-point unit may execute the same floating-point instruction stream twice. Prior to the integer instructions retiring, compare logic may detect a mismatch between execution results from each of the integer execution units. In addition, prior to the results of the floating-point instruction stream transferring out of the floating-point unit, the compare logic may also detect a mismatch between results of execution of each consecutive floating-point instruction stream. Further, in response to detecting any mismatch, the compare logic may cause instructions causing the mismatch to be re-executed.

Systems and methods that, among other things, analyze and monitor the performance of a call center including performance of the interactive voice response (IVR) systems, call center agents, and other components of the call center. The systems and methods record characteristics of the call such as the audio data, and analyze that record to identify the events and the actions that take place during the call. These events and actions may be defined as complex customer / call center interactions, such as dropped calls, logic errors or other event. A call center administrator may also identify a set of metrics, such as the number of dropped calls that occur during a day or for each agent, the number of times a client was left on hold for more than two minutes, or other such metrics that may be monitored by the systems described herein. The data collected about these events and the resulting metrics may be stored in a database and provided to a call center administrator through a user interface that allows the administrator to browse through the collected metric and recorded call data and directly review relevant portions of a call that are of interest to the administrator.
