ABSTRACT:
A method accumulates the status of the execution of an arithmetic operation by an arithmetic processor having hardware elements for performing the steps of the operation, where each step is based on one or more operands and produces an intermediate or final result and possibly produces a corresponding status indicator. The method includes simulating the hardware elements in a model that performs simulated steps analogous to the steps performed by the hardware elements, each simulated step resulting in an intermediate or final status result; and while the arithmetic processor executes the arithmetic operation, applying each status indicator to the point in the model that corresponds to the point in the arithmetic processor where the result corresponding to the status indicator is applied, whereby the final result of the operation of the model will represent the accumulated status of the execution of the arithmetic operation.
