ABSTRACT:
An apparatus, system and method for detecting errors in a physical interface during the transmission and/or receipt of data communications between integrated circuits (“ICs”) are disclosed. In one embodiment, an apparatus for generating error-detection codes in a physical interface for the transmission of data communications between integrated circuits (“ICs”) includes an N-bit-to-N+2-bit (“N bit/(N+2) bit”) physical layer (“PHY”) encoder configured to insert a physical interface error detection bit with N application data bits to form N+1 unencoded data bits, and encode said N+1 unencoded data bits to yield N+2 encoded data bits. The apparatus further includes an error-detection code generator configured to generate a number of bits constituting an error-detection code that includes said physical interface error detection bit, wherein N represents any integer number of data bits.
