Corrupt packet detector for C-PHY receiver

A method for operating a communication interface circuit, comprising:

• converting a serial stream of 3-bit symbols received from a three-wire serial bus to a parallel multi-symbol word comprising a plurality of symbols ordered in accordance with time of arrival at an input of a deserializer;
• using detection circuits to determine whether a pattern of symbols in the parallel multi-symbol word indicates a corrupt data packet;
• and
• activating one or more flags responsive to feedback received from the detection circuits, wherein each flag is configured to cause termination of reception of the corrupt data packet when the each flag is active.

An apparatus, comprising:

• means for converting a serial stream of 3-bit symbols received from a three-wire serial bus to a parallel multi-symbol word comprising a plurality of symbols ordered in accordance with time of arrival at an input of a deserializer;
• means for pattern matching configured to determine whether a pattern of symbols in the parallel multi-symbol word indicates a corrupt data packet;
• and
• means for activating one or more flags responsive to feedback received from the means for pattern matching, wherein each flag is configured to cause termination of reception of the corrupt data packet when the each flag is active.

A non-transitory processor-readable storage medium comprising code configured to cause a processing circuit to:

• convert a serial stream of 3-bit symbols received from a three-wire serial bus to a parallel multi-symbol word comprising a plurality of symbols ordered in accordance with time of arrival at an input of a deserializer;
• use detection circuits to determine whether a pattern of symbols in the parallel multi-symbol word indicates a corrupt data packet;
• and
• activate one or more flags responsive to feedback received from the detection circuits, wherein each flag is configured to cause termination of reception of the corrupt data packet when the each flag is active.
