Abstract
A communication circuit for verified communication comprising a transmitter having input terminals to receive a data word, an encoder configured to encode the data word to create an encoded word different from the data word, and output terminals configured to transmit the data word and the encoded word. A receiver is coupled to the transmitter and includes input terminals to receive the data word as a received word and the encoded word, a decoder configured to decode the encoded word to create a decoded word, and a comparator configured to compare the received word and the decoded word to create a select signal, and a selector responsive to the select signal and configured to select the received data word or the decoded word based at least in part on the select signal. Advantages of the invention include the ability to verify redundant received data without decreasing bandwidth or increasing latency.
