A method for detecting the end-of-frame of a CAN FD frame in an input bit stream entails providing a recessive bit count; defining a stretched bit transmission time longer than the bit transmission time associated with the high data rate; stretching the bit transmission time of each dominant bit succeeding a recessive bit in the input bit stream to the stretched bit transmission time to generate a conditioned input bit stream; sampling the conditioned input bit stream at a bit counter rate to generate a sampled bit stream; resetting the recessive bit count in response to each dominant bit in the sampled bit stream; and incrementing the recessive bit count in response to each recessive bit in the sampled bit stream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"CAN FD end-of-frame detector, CAN bit stream processing device, method for detecting the end of a CAN FD frame, and method of operating a CAN bit stream processor","description":"A CAN FD frame comprises one or more portions provided at a normal bit rate that includes an end-of-frame field consisting of a succession of at least seven recessive bits.
