ASYMMETRIC CHIP-TO-CHIP INTERCONNECT

摘要

Methods and apparatus apparatuses to transfer data between a first device and a second device are disclosed. In various embodiments, an apparatus includes a first device and a second device. The first device includes at least one first non-differential transmitter coupled to a first channel, at least one second non-differential transmitter coupled to a second channel, and at least one differential receiver to receive a data bit and its complement on the first and second channels in parallel. The second device includes at least one first non-differential receiver coupled to the first channel, at least one second non-differential receiver coupled to the second channel, and at least one differential transmitter to transmit a data bit and its complement on the first and second channels in parallel. Other methods and apparatuses are disclosed.
