Methods for managing communications involving a lockstep processing system

A method for managing communications involving a lockstep processing system comprising at least a first processor and a second processor, the method comprising:

• receiving, at a first processing lane of a data synchronizer, a first signal from a first device;
• transmitting, by a cross-channel interface of the data synchronizer,
• the first signal to a second processing lane of the data synchronizer;
• transmitting, by the data synchronizer, the first signal from the first processing lane to the lockstep processing system;
• and
• transmitting, by the data synchronizer, the first signal from the second processing lane to the lockstep processing system,
• wherein transmission of the first signal from the first processing lane to the first processor occurs synchronously with transmission of the first signal from the second processing lane to the second processor,
• receiving, at the first processing lane of the data synchronizer, a second signal from the lockstep processing system;
• receiving, at the second processing lane of the data synchronizer, a third signal from the lockstep processing system;
• transmitting, by the cross-channel interface of the data synchronizer, the second signal to compare logic of the second processing lane;
• and
• transmitting, by the cross-channel interface of the data synchronizer, the third signal to compare logic of the first processing lane;
• wherein the lockstep processing system generates both the second signal and the third signal in response to receiving the first signal.
