Patent ID: 7062586

Claim:
A system for inter-module communication, comprising: a printed circuit board having traces; a cross-bar switch integrated circuit attached to said printed circuit board for electrical communication among said traces; and a programmable logic device integrated circuit attached to said circuit board for electrical communication over said traces, said programmable logic device integrated circuit including a first module and a second module, said first module and said second module each including a hardwired transceiver coupled to a serial/parallel interface, each said transceiver configured with at least one signal conductor for serial communication between said first module and said second module over said traces and through said cross-bar switch, said first module and said second module being configured to communicate with one another asynchronously, each said transceiver being configured to communicate with a respective said serial/parallel interface in a synchronous time domain, each said serial/parallel interface being coupled to a respective portion of programmable logic of said programmable logic device.
