Arithmetic Logic Unit is one of the processors function module, used to perform such as add, subtract, multiply and divide as well as the value of the register between the logic operation, usually in a general processor is set into a cycle of operation a rising edge, which is mainly composed of attached to the ALU input and output registers as well as in the ALU input insert bypass multiplier decision.
ALU:
Pentinum 4 ALU is very surprising, Intel was using 0.18 microns aluminum connecting technology to manufacture the delay time is less than 0.35ns Rapid Execution Engine ( rapid execution engine ), which includes a load / store address generator, can be in the up and down along at the same time sequential operation, using the ALU, in theory the computational processor can be increased to two times. So that the computation speed.
