TL;DR: The eXtreme Processing Platform (XPPTM) is a new runtime-reconfigurable data processing architecture based on a hierarchical array of coarsegrain, adaptive computing elements, and a packet-oriented communication network that is well suited for applications in multimedia, telecommunications, simulation, signal processing, graphics, and similar stream-based application domains.
Abstract: The eXtreme Processing Platform (XPPTM) is a new runtime-reconfigurable data processing architecture. It is based on a hierarchical array of coarsegrain, adaptive computing elements, and a packet-oriented communication network. The strength of the XPPTM technology originates from the combination of array processing with unique, powerful run-time reconfiguration mechanisms. Parts of the array can be configured rapidly in parallel while neighboring computing elements are processing data. Reconfiguration is triggered externally or even by special event signals originating within the array, enabling self-reconfiguring designs. The XPPTM architecture is designed to support different types of parallelism: pipelining, instruction level, data flow, and task level parallelism. Therefore this technology is well suited for applications in multimedia, telecommunications, simulation, signal processing (DSP), graphics, and similar stream-based application domains. The anticipated peak performance of the first commercial device running at 150 MHz is estimated to be 57.6 GigaOps/sec, with a peak I/O bandwidth of several GByte/sec. Simulated applications achieve up to 43.5 GigaOps/sec (32-bit fixed point).

TL;DR: Extensions to the Stream Control Transmission Protocol (SCTP) are described that provide methods to reconfigure IP address information on an existing association and request that a peer set flow limits in units of bytes or messages, either on a per- stream or per-association basis.
Abstract: This document describes extensions to the Stream Control Transmission
Protocol (SCTP) [RFC2960] that provide methods to (1) reconfigure IP
address information on an existing association and (2) request that a
peer set flow limits in units of bytes or messages, either on a per-
stream or per-association basis.

TL;DR: This brief investigates the finite-time control problem associated with attitude stabilization of a rigid spacecraft subject to external disturbance, actuator faults, and input saturation and develops a novel fixed-time sliding mode surface, and the settling time of the defined surface is shown to be independent of the initial conditions of the system.
Abstract: This brief investigates the finite-time control problem associated with attitude stabilization of a rigid spacecraft subject to external disturbance, actuator faults, and input saturation. More specifically, a novel fixed-time sliding mode surface is developed, and the settling time of the defined surface is shown to be independent of the initial conditions of the system. Then, a finite-time controller is derived to guarantee that the closed-loop system is stable in the sense of the fixed-time concept. The actuator-magnitude constraints are rigorously enforced and the attitude of the rigid spacecraft converges to the equilibrium in a finite time even in the presence of external disturbances and actuator faults. Numerical simulations illustrate the spacecraft performance obtained using the proposed controller.

TL;DR: The distinguished feature of the new controller architecture is that it shows structurally how the controller design for performance and robustness may be done separately which has the potential to overcome the conflict between performance and resilientness in the traditional feedback framework.
Abstract: We propose a new feedback controller architecture. The distinguished feature of our new controller architecture is that it shows structurally how the controller design for performance and robustness may be done separately which has the potential to overcome the conflict between performance and robustness in the traditional feedback framework. The controller architecture includes two parts: one part for performance and the other part for robustness. The controller architecture works in such a way that the feedback control system can be solely controlled by the performance controller when there is no model uncertainties and external disturbances and the robustification controller can only be active when there are model uncertainties or external disturbances.
