Abstract

In a semiconductor device comprising photo-transceiver arrays constructed on silicon substrates with underlying supporting CMOS circuitry in the substrate interfacing with a source of software control, a method is provided for mapping and reconfiguring the global data transfer channel map of optical interconnect lines and intra-nodal routing links. An initial mapping procedure identifies all possible connections. The silicon circuitry provides for sensing optical connections and light levels, for testing or sensing of routing links, and for controlling gain and power, as well as forming and reforming routing links between detectors and emitters. A rule-based routing, mapping and re-mapping scheme, utilizing over-sampling techniques and effectuated by the silicon circuitry and software, accommodates limited misalignment of mating photo-arrays, faults occurring in data transmission channels after the initial mapping, and provides additional security, performance and power management capabilities.

Dependent claims

A method for mapping at least one data transfer channel within a system comprising first and second arrays of transceivers, said first and second arrays of transceivers each comprising at least one emitter and at least one detector, said method comprising:

activating a first said emitter in said first array of transceivers;
scanning each said detector in said second array of transceivers, said second array of transceivers being optically coupled to said first array;
recognizing if at least one said detector in said second array receives light emitted from said first emitter in said first array of transceivers;
identifying each said detector in said second array of transceivers that receive light enmitted from said emitter;
repeating said process for each said emitter in said first array of transceivers;
establishing at least one unique inter-nodal optical interconnect between said first and second arrays;
mapping at least one intra-nodal electrical routing link between said at least one emitter and said at least one detector of said first array;
and
constructing a map of said data transfer channel.
