PROGRAMMABLE CROSSBAR STRUCTURES IN ASYNCHRONOUS SYSTEMS

Methods, systems, and circuits for forming and operating a crossbar structure in an asynchronous system are described. One or more input ports of a programmable crossbar structure may be connected to send data to one or more output ports. A group of output ports each receiving data from an input port may be connected to send, in response, control signals via a programmable element to the input port. The number of programmable elements used may be determined by the number of input ports being copied to more than one output port. Additional methods, systems, and circuits are disclosed.
