Methods, systems, and computer program products for asymmetric multimode interconnect

摘要

Methods, systems, and computer readable media for asymmetric multimode interconnect (MMI) are disclosed. According to one aspect, a system for receiver-side asymmetric MMI includes a receiver that receives binary-encoded input signals from a multichannel interconnect, encodes the received binary-encoded signals according to a multimode encoding equation to produce multimode-encoded signals having voltage levels according to the multimode encoding equation, adjusts the timing of the multimode-encoded signals to compensate for multichannel interconnect channel delays to produce delay-adjusted multimode-encoded signals, and decodes the delay-adjusted multimode-encoded signals according to a multimode decoding equation to produce binary-encoded output signals. According to another aspect, a system for transmitter-side asymmetric MMI includes a transmitter that receives binary-encoded input signals, pre-adjusts the timing of the input signals to compensate for expected multichannel interconnect channel delays, multimode-encodes the timing-compensated binary-encoded input signals, multimode-decodes the multimode-encoded signals, and transmits the multimode-decoded signals over the multichannel interconnect.
