Abstract: Embodiments combine error correction code (ECC) and transparent memory built-in self-test (TMBIST) for memory fault detection and correction. An ECC encoder receives input data and provides ECC data for data words stored in memory. Input XOR circuits receive the input data and output XOR'ed data as payload data for the data words. Output XOR circuits receive the payload data and output XOR'ed data. An ECC decoder receives the ECC data and the XOR'ed output data and generates error messages. Either test data from a controller running a TMBIST process or application data from a processor executing an application is selected as the input data. Either test address/control signals from the controller or application address/control signals from the processor are selected for memory access. During active operation of the application, memory access is provided to the processor and the controller, and the memory is tested during the active operation.

Abstract: A mainframe-based far-distance bicentric transaction information processing system, providing a processing operation solution. The method includes: receiving upload transaction information containing transaction type data; searching transaction information requiring an amount of shared resource less than a preset threshold when being processed, according to the transaction type data; and transmitting the transaction information requiring the amount of shared resource less than the preset threshold when being processed, to a backup processing center to be processed, when CPU utilization rates exceeds a preset safety threshold. The system includes a main processing center and a backup processing center.

Abstract: An iterative decoding method is disclosed and includes sequentially executing a number of iterative decoding cycles in relation to a parity check equation until the parity check equation is resolved, or a maximum number N of iterative decoding cycles is reached, during execution of the number of iterative decoding cycles, storing in a data buffer minimum estimated values for a set of variable nodes corresponding to a minimum number of bit errors, and outputting the minimum estimated values stored in the data buffer as a final decoding result when the number of iterative decoding cycles reaches N.
