Apparatus and method for an enhanced integer divide in an IA64 architecture |
摘要 |
An apparatus and method for performing integer divide operations in an IA64 architecture based data processing system is provided. The apparatus and method insert integer divide checks in place of NOP instructions in the instruction bundles associated with integer divide operations. The checks serve to identify typically encountered integer divide operations. Based on such identifications, the integer divide operation may be short-circuited such that the appropriate result may be returned without having to complete the integer divide operation.
