A hybrid processor system for use on board a telecommunications multi-beam satellite is provided that is controllable by a network control center via one or more control channels.

A non-blocking crossbar switch architecture is disclosed that circumvents the problem present in prior art crossbar switches where input signals may oversubscribe the available inter-die bandwidth. The new non-blocking crossbar switch architecture is split across a plurality of semiconductor dice, including a plurality of interleaved crossbar switch segments. Only one crossbar switch segment is implemented on each semiconductor die. A plurality of input ports and output ports are coupled to the crossbar switch. The crossbar switch is non-blocking, i.e. any one output port not currently receiving data may receive data from any one input port.

Sparse representation of information performs powerful feature extraction on high-dimensional data and is of interest for applications in signal processing, machine vision, object recognition, and neurobiology. Sparse coding is a mechanism by which biological neural systems can efficiently process complex sensory data while consuming very little power. Sparse coding algorithms in a bio-inspired approach can be implemented in a crossbar array of memristors (resistive memory devices). This network enables efficient implementation of pattern matching and lateral neuron inhibition, allowing input data to be sparsely encoded using neuron activities and stored dictionary elements. The reconstructed input can be obtained by performing a backward pass through the same crossbar matrix using the neuron activity vector as input. Different dictionary sets can be trained and stored in the same system, depending on the nature of the input signals. Using the sparse coding algorithm, natural image processing is performed based on a learned dictionary.
