Abstract
A value that bypasses some of the computations for an arithmetic operation can be supplied for performance of a dependent arithmetic operation without waiting for completion of the computations of the arithmetic operation. During performance of a first arithmetic operation, a value is generated. The value is viable for use in performing a second arithmetic operation that is dependent upon the first arithmetic operation. The value is utilized to continue performance of the first arithmetic operation and commence performance of the second arithmetic operation. As part of the continued performance of the first arithmetic operation, determining whether the value is to be modified for the first arithmetic operation. Compensating for modifications to the value for performance of the second arithmetic operation.
