Abstract: A method for ensuring guaranteed services for real-time traffic on an interconnect with errors is provided. The real-time traffic comprises a first and second traffic class (HRT, SRT). Real-time traffic of the first and/or second traffic class (HRT, SRT) is transmitted from a transmitter to a receiver. It is detected by the receiver whether an error has occurred during the transmission of the real-time traffic and the error is reported to the transmitter. At least part of the real-time traffic of the second traffic class (SRT) is re-transmitted by the transmitter if the transmitter has received an error report from the receiver within a predetermined time period.

Abstract: A system for managing communications to add a first Remote Direct Memory Access (RDMA) link between a TCP server and a TCP client, where the first RDMA link references first remote memory buffer (RMB) and a second RMB, and further based on a first remote direct memory access network interface card (RNIC) associated with the TCP server and a second RNIC associated with the TCP client. The system determines whether a third RNIC is enabled. The system adds a second RDMA link, responsive to a determination that the third RNIC is enabled. The system detects a failure in a failed RDMA link. The system reconfigures the first RDMA link to carry at least one TCP message of a connection formerly assigned to the failed RDMA link, responsive to detecting the failure. The system communicates at least one message of the at least one connection on the first RDMA link.

Abstract: A diagnostic handling server is capable of supporting users without operator support, in which the proper handling of a problem, which users know through experience, can be reflected in the support. Preliminarily, data (e.g., dissatisfying item data) on the item with which a user feels dissatisfied and diagnostic data on the diagnoses of the electric appliances are collected from the electric appliances to be supported. The feature points of the respective electric appliances with which the user feels dissatisfied are then extracted from the collected diagnostic data. When the user feels dissatisfied with a specific electric appliance, the diagnostic data of the electric appliance is transmitted together with a search request for the proper handling, the transmitted diagnostic data is compared with the preliminarily extracted feature point, and information on the cause and the proper handling is provided to the user.

Abstract: A method for specifying a transport block-to-codeword mapping relationship and a method for transmitting a downlink signal using the same are described. If a swap flag has a first logic value, a first transport block is mapped to a first codeword and a second transport block is mapped to a second codeword. If the swap flag has a second logic value, the first transport block is mapped to the second codeword and the second transport block is mapped to the first codeword. If the size of any one of two transport blocks is 0, the swap flag is not used.

Abstract: A method for correcting faults in semiconductor memory components provides an application system having a multichip module (1) which has a semiconductor memory component (2) containing a volatile memory and a diverting circuit (7). When the application system is being booted up, addresses of faulty memory cells in the semiconductor memory component (2) are loaded into the multichip module (1), with the result that the diverting circuit (7) diverts access to a memory cell in the replacement data memory if a faulty memory cell in the semiconductor memory component (2) is accessed.

Abstract: Embodiments of the invention include methods, apparatuses, and systems for automatically identifying a synchronization sub-pattern associated with a test pattern. A test and measurement instrument is triggered in response to a first instance of a trigger pattern in a data stream. A trigger-to-trigger counter begins counting at the time of the first trigger event. The test and measurement instrument is again triggered in response to a second instance of the trigger pattern in the data stream. The count is ended at this time. The count is then compared to a predefined length of the test pattern, and if equal, it is automatically determined that the trigger pattern is the unique synchronization sub-pattern associated with the test pattern.

Abstract: A data scrubbing apparatus corrects disturb errors occurring in a memory cell array, such as SMT MRAM cells. The data scrubbing apparatus activates scrubbing of the data and associated error correction bits based on a number of errors corrected, at a power up of the memory cell array, or a programmed time interval. The data scrubbing apparatus may generate an address describing the location of the memory cells to be scrubbed. The data scrubbing apparatus then commands the array of memory cells to write back the corrected data, the associated error correction bits, and reference bits. The data scrubbing apparatus provides a busy indicator externally during a write back of corrected data.
