System, method, and computer program product for end-to-end CRC overhead hiding

An end-to-end cyclic redundancy check (CRC) overhead hiding method, comprising:

• accessing, by a microprocessor, a data block storing message data;
• obtaining, by the microprocessor, a first instruction for serializing a communication;
• obtaining, by the microprocessor, a second instruction for computing a CRC checksum;
• and
• interleaving, by the microprocessor, the CRC checksum with serialized message data to generate a communication within a communication channel, by computing a serialized communication of the message data in the data block based on the first instruction, while concurrently computing the CRC checksum for the message data based on the second instruction,
• wherein the communication channel comprises a shared memory buffer of at least one of an autonomous vehicle (AV), a sensor system of the AV, or an on-board computing device of the AV, and the end-to-end CRC overhead hiding method further comprises:
• sending the CRC checksum with the serialized message data to a plurality of components via the shared memory buffer.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to:

• access a data block storing message data;
• obtain a first instruction for serializing a communication;
• obtain a second instruction for computing a cyclic redundancy check (CRC) checksum;
• interleave the CRC checksum with serialized message data to generate a communication within a communication channel, by computing a serialized communication of the message data in the data block based on the first instruction, while concurrently computing the CRC checksum for the message data based on the second instruction;
• divide a message into a plurality of data blocks, each of the plurality of data blocks storing an amount of message data to satisfy a threshold requirement for hiding a CRC computation;
• and
• accumulate a CRC message while computing a serialized communication of the message data by chaining executions of the first instruction and the second instruction for each of the plurality of data blocks while executing an instruction for a current CRC and a next data block of the plurality of data blocks to process.
