ABSTRACT:
The present invention is a method and apparatus for reporting exception in a single instruction multiple data (SIMD) processor in computing an arithmetic function for a plurality of argument data. The SIMD processor is configured for processing N elements simultaneously. A sequence of instructions is re-arranged to allocate the plurality of argument data in the N elements. The N elements are processed simultaneously. The exceptions for N elements are detected simultaneously. The detected exceptions are then combined to generate a global exception.
