Abstract :
The techniques of pipelining, superscalar execution, and branch prediction used in the Pentium CPU, which integrates 3.1 million transistors in 0.8- mu m BiCMOS technology, are described. The technology improvements associated with the three most recent microprocessor generations are outlined. The Pentium´s compatibility, performance, organization, and development process are also described. The compiler technology developed with the Pentium microprocessor, which includes machine-independent optimizations common to current high-performance compilers, such as inlining, unrolling, and other loop transformations, is reviewed.<>
