METHOD AND APPARATUS FOR DETECTING AND CORRECTING ERRORS IN A PARALLEL TO SERIAL CIRCUIT

摘要

A circuit (301 ) has first portion (302) that receives data at a first rate; a second portion (305) that outputs data at a second rate synchronized to and different from the first rate; a third portion (350) that transfers data from the first portion (302) to the second portion (305); and a fourth portion (361 ) that generates an error detected signal in response to a disruption in the synchronism between the first and second rates. A different aspect involves a method that includes: receiving data at a first rate in a first portion (302); transferring data from the first portion (302) to a second portion (305); outputting data at a second rate from the second portion (305), the second rate being synchronized to and different from the first rate; and generating an error detected signal in response to detection of a disruption in the synchronism between the first and second rates.
