Abstract:
1. A digital signal processing integrated circuit comprising: an array of interconnected and programmed or programmable digital signal processors, at least some of the digital signal processors having IO ports, said digital signal processors including programs for establishing interconnections among said digital signal processors; an IO connection for communicating a signal stream between signal processors in the array and circuitry outside the array; a configurable multiplexing circuit between the IO connection and the IO ports of at least a plurality of the digital signal processors, the multiplexing circuit being configurable under control of configuration data, the multiplexing circuit being arranged to give the effect of accessing the IO connection only to IO signals from the IO port or ports of one or ones of the respective plurality of digital signal processors that are selected by the configuration data, wherein execution of programs within said digital signal processors determines a configuration state of said configurable multiplexing circuit.
