Herein is disclosed an integrated input/output (I/O) processing system, comprising an I/O port, configured to receive I/O data and to deliver the I/O data to one or more processors; one or more processors, further comprising a first processing logic and a second processing logic, wherein the one or more processors are configured to deliver the received I/O data to the first processing logic and to the second processing logic, and wherein the first processing logic and the second processing logic are configured to redundantly process the I/O data; and a comparator, configured to compare an output of the first processing logic and an output of the second processing logic.

In at least one embodiment of the disclosure, a method includes detecting an error in a local memory shared by redundant computing modules executing in delayed lockstep. The method includes pausing execution in the redundant computing modules and handling the error of the local memory. The method includes resuming execution in delayed lockstep of the redundant computing modules in response to the handling of the error.

A memory system includes a controller configured to transfer first data for a program operation, and a memory device configured to perform an error check operation for determining whether second data received from the controller are equal to the first data and the program operation for storing the first data.

A network includes a plurality of nodes and a plurality of links communicatively coupling each of the nodes to at least one respective adjacent node via a first communication channel and to another respective adjacent node via a second communication channel. The nodes and links have a braided ring topology. First and second nodes of the plurality of nodes source data, are adjacent nodes, and at least one is a source node. The first node sends a first communication to the second node via a third node that is adjacent the first node and via a fourth node that is adjacent the second node. The second node sends a second communication to the first node via the third node and via the fourth node. At least one of the first and second nodes terminates transmission of the first and second communications when the first and second communications do not match.

A memory system includes a controller configured to transfer first data for a program operation, and a memory device configured to perform an error check operation for determining whether second data received from the controller are equal to the first data and the program operation for storing the first data.

A first server of a storage controller is configured to communicate with a host via a first bus interface, and a second server of the storage controller is configured to communicate with the host via a second bus interface. Data is written from the host via the first bus interface to a cache of the first server and via the second bus interface to a non-volatile storage of the second server. The data stored in the cache of the first server is periodically compared to the data stored in the non-volatile storage of the second server.

A method for controlling a vehicle includes: establishing, by a vehicle controller, a connection between a client and a plurality of servers, the plurality of servers includes a primary server and at least one replica server, the at least one replica server is a replica of the primary server; making, by the vehicle controller, a data request about a given service to the plurality of servers; in response to the data request, receiving reply data from the plurality of servers to the data request via a middleware; fusing, by the middleware, the reply data from the plurality of servers to generate a resulting data; receiving, by the vehicle controller, the resulting data; and controlling, by the client, the vehicle based on the resulting data.

Devices systems and methods are disclosed providing a highly fault tolerant Command, Control, and Data Handling (CC&DH) system immune to byzantine faults. The system includes a plurality of High Integrity Computing Elements each capable of delivering data immune to byzantine faults, an arbitrary communication interface, and a number of peripheral devices providing input and output to the system. The system is capable of providing high integrity data immune to byzantine faults throughout the system. Using one greater High Integrity Computing Elements than the number of faults required allows for implementation of a wide range of redundant systems including dual, triple, quad, and beyond redundancy using voting computers. The system is implemented using any number of standard computing elements, which is greater than two, a communication abstraction, data exchange, mission algorithm, and data comparison producing data immune to byzantine errors to the remaining peripherals in the system.

Integrated circuit packages with multiple integrated circuit dies are provided. A multichip package may include a master die that is coupled to one or more slave dies via inter-die package interconnects. A mixed (i.e., active and passive) interconnect redundancy scheme may be implemented to help repair potentially faulty interconnects to improve assembly yield. Interconnects that carry normal user signals may be repaired using an active redundancy scheme by selectively switching into use a spare driver block when necessary. On the other hand, interconnects that carry power-on-reset signals, initialization signals, and other critical control signals for synchronizing the operation between the master and slave dies may be supported using a passive redundancy scheme by using two or more duplicate wires for each critical signal.

A transmission control method for HARQ is provided for improving HARQ performance in a mobile communication system. The transmission control method for Hybrid Automatic Repeat reQuest (HARQ) in a mobile communication system according to the present invention includes receiving an downlink resource assignment message; determining whether configured downlink assignment has been indicated to an HARQ entity since a previously received downlink assignment for a User Equipment's (UE's) Cell-Radio Network Temporary Identifier (C-RNTI) for the same HARQ process; maintaining, if the configured downlink assignment has not been indicated to the HARQ entity, the HARQ process; and processing, if the configured downlink assignment has been indicated to the HARQ entity, the downlink resource assignment message as a resource assignment message for initial transmission.
