Abstract
A dual lock step processor system includes a first processor connected to a first memory, a second processor connected to a second memory, compiler engine, a first instruction engine operably connected to a first memory, and a second instruction engine operably connected to a second memory. The first instruction engine is configured to store a program value; encode the first program value using a first differential encoding and the compiler engine to generate a first encoded program value; and write the first encoded program value into a first address location of a plurality of first address locations. The second instruction engine is configured to store a program value; to encode the first program value using a second differential encoding and the compiler engine to generate a second encoded program value and write the second encoded program value into a second address location of a plurality of second address locations corresponding to the first selected address location.
