AP-526 Optimizations For Intel's 32-Bit Processors

The Intel386(TM) Architecture Family, including the Intel386, Intel486(TM), Pentium(R) and Pentium (R) Pro, represents a series of compatible processors. The newer members of the family are capable of executing any binaries created for members of previous generations. For example, any existing 8086/8088, 80286, Intel386 (DX or SX), and Intel486 processor applications will execute on the Pentium and Pentium Pro processors without any modification or recompilation. However, there are certain code optimization techniques which will make applications execute faster on a specific member of the family with little or no impact on the performance of other members. Most of these optimizations deal with instruction sequence selection and instruction reordering to complement the processor micro-architecture
