Abstract: Various examples described herein are directed to systems and methods for providing a user interface at a plurality of computing devices. A first interface application executing at a first computing device may determine a first state for a user interface. The first interface application may detect a set of user computing devices for providing the user interface to a user and select a second computing device that is in the set of user computing devices based at least in part on the first state of the user interface. The first interface application may send a description of the user interface to the second computing device.

Abstract: A circuit is disclosed which combines the functions of a cyclic redundancy check code (CRCC) generator and a pseudo-random number generator in such a way that common elements are shared rather than duplicated. A 16-stage shift register and two linear feedback paths are included for the CRCC and pseudo-random number generators. A control section of the circuit controls the mode of operation of the circuit according to the state of a mode control signal. A signal on a clear line resets the shift register or initializes it with a selected value depending on the state of the mode control signal. The mode control signal also controls the input of data on a data line and the output of generated CRC and pseudo-random access codes on output lines.
