Abstract: An integrated analog to digital converting and digital to analog converting (ADDA) RF transceiver for satellite applications, configured to replace conventional analog RF down and up conversion circuitry. The ADDA RF transceiver includes one of more ADCs, DSPs, and DACs, all on a single ASIC. Further, the circuitry is to be radiation tolerant for high availability and reliability in the ionizing radiation environment present in the space environment.

Abstract: An integrated analog to digital converting and digital to analog converting (ADDA) RF transceiver for satellite applications capable of flexibly processing high-bandwidth and low-bandwidth RF input signal(s). The RF transceiver may selectively distribute high-bandwidth RF input signals among one or more DSP pipelines for parallel processing of the RF input signals, and the RF transceiver may coherently recombine the processed signals from the one or more DSP pipelines to generate an RF output signal. The ADDA RF transceiver includes one or more ADCs, DSPs, and DACs, all on one or more ASICs, FPGAs, or modular electronic devices in a single semiconductor package. Further, the RF transceiver is radiation tolerant at the module, circuit, and/or system level for high availability and reliability in the ionizing radiation environment present in the space environment.

Abstract: Methods, systems, and devices for configuration and upset recovery of reconfigurable devices are provided. A central program/recovery manager (CPRM) is coupled with each of a number of reconfigurable devices. The reconfigurable devices are programmed/configured by the CPRM, which then periodically monitors each of the reconfigurable devices to detect if one or more of the devices has experiences an upset. In the event of an upset, the CPRM may attempt to reset the reconfigurable device, scrub a memory of the reconfigurable device, or reprogram the reconfigurable device. A memory module is coupled with the CPRM and each of the reconfigurable devices that stores bit or programming files that may be used to program and/or reprogram the reconfigurable devices.

Abstract: Methods, systems, and devices for distributed computing are provided. Clusters of nodes are provided, each node have a communication link to a primary I/O switch as well as to two other nodes, thereby providing redundant alternative communication paths between different components of the system. Primary and redundant I/O switching modules may provide further redundancy for high availability and high reliability applications, such as applications that may be subjected to the environment as would be found in space, including radiation effects. Nodes in a cluster may provide data storage, processing, and/or input/output functions, as well as one or more alternate communications paths between system components. Multiple clusters of nodes may be coupled together to provide enhanced performance and/or reliability.
