Abstract
A method and device for performing failsafe computation, and a method of compiling code to perform a failsafe computation are provided. The method includes performing a first calculation (212) to generate a first result (214). A second calculation (218) is performed using a scalar (216) and the first calculation (212) to generate a second result (220). The second calculation (218) includes multiplying the first calculation (212) by the scalar (216) to generate a scaled result, and dividing the scaled result by the scalar (216) to generate the second result (220). The first result (214) and the second result (220) are compared to determine if they are equivalent.
