Fault-Secure Interface Between Fault-Tolerant RAM and Transmission Channel Using Systematic Cyclic Codes

The problem of designing a fault-secure interface between a fault-tolerant RAM memory system and a transmission channel, both protected against errors using cyclic linear error detecting and/or correcting codes is considered. The main idea relies on using the RAM check bits to control the correct operation of the parallel cyclic code encoder, so that the whole interface has no single point of failure.
