The hyper-pipelined technology doubles the pipeline depth in the Pentium 4 processor on
0.13 micron process, allowing the processor to reach much higher core frequencies. The rapid
execution engine allows the two integer ALUs in the processor to run at twice the core frequency;

execution engine allows the two integer ALUs in the processor to run at twice the core frequency;
this allows many integer instructions to execute in 1/2 clock cycle. The 400 MHz, 533 MHz, or
800 MHz system bus is a quad-pumped bus running off a 100 MHz or a 133 MHz system clock,
making 3.2 Gbytes/sec, 4.3 Gbytes/sec, or 6.4 Gbytes/sec data transfer rates possible. The
