Abstract:
A multiprocessor device is provided that includes a plurality of processors in which each processor of the plurality of processors includes an interrupt controller, and a symmetric interrupt crossbar having a plurality of interrupt inputs in which each interrupt input that is not reserved is coupled to a respective interrupt output of an interrupt source of a plurality of interrupt sources, and a plurality of interrupt outputs in which each interrupt output is coupled to a respective interrupt input of an interrupt controller of one of the plurality of processors, in which the symmetric interrupt crossbar is programmable to map an interrupt signal from any interrupt source of the plurality of interrupt sources coupled to the symmetric interrupt crossbar to any interrupt input of any interrupt controller coupled to the symmetric interrupt crossbar.
