An end-to-end residue-based protection scheme protects multiple units/blocks of a floating point execution pipeline without the complexity and cost of having multiple protection schemes for the execution pipeline. Protecting an execution pipeline that supports floating point operations includes factoring in component operations, such as normalization and rounding, into a residue generated for a result. In addition, residues of operands are distilled to extract their corresponding mantissa residues, thus allowing the floating point operations (e.g., multiplication, addition, etc.) to be applied to the mantissa residues.
