An SMT based method for optimizing arithmetic computations in embedded software code
2013
2013 Formal Methods in Computer-Aided Design
We present a new method for optimizing the source code of embedded control software with the objective of minimizing implementation errors in the linear fixed-point arithmetic computations caused by overflow, underflow, and truncation. Our method relies on the use of the satisfiability modulo theory (SMT) solver to search for alternative implementations that are mathematically equivalent but require a smaller bit-width, or implementations that use the same bit-width but have a larger error-free
