Classic Pentium divided into four water each integer pipeline

First understand explain the super-pipelined superscalar pipeline (pipeline). The pipeline is the Intel 486 chip for the first time start using. The pipeline work like industrial production on the assembly line. An instruction processing pipeline from 5-6 different functions of circuit unit in the CPU, an X86 instruction into steps 5-6, then perform these circuit elements, so that can be achieved in a CPU clock cycles to complete an instruction , and therefore improve the computing speed of the CPU. Classic Pentium divided into four water each integer pipeline, instruction prefetch, decode, execute, and write back the result, the floating-point water is divided into eight water.

Superscalar through the built-in multi-lines simultaneously perform multiple processors, and its essence is space for time.  For example, the Pentium 4 pipeline up to 20. Step (level) of the pipeline design the longer, the completion of one instruction faster, so it can adapt to the working frequency higher CPU. But the pipeline is too long also bring some side effects are likely to occur with higher frequency lower actual CPU operation speed phenomenon Intel Pentium 4 appeared in this case, it clocked up to 1.4G or more AMD 1.2G Athlon, but the computational performance is far less than even the Pentium III.

12. Package
The CPU package specific material curing the CPU chip or the CPU module in which protective measures to prevent damage, must generally be packaged CPU can be delivered to users. CPU package depends on the CPU installed in the form and integrated device design, from the the large classification point of view usually Socket socket CPU PGA (Land Grid Array) package installed, while the use of the CPU Slot x slot installation, all with the SEC (unilateral patch box) packaging. Also of PLGA (Plastic Land Grid Array), OLGA (Organic Land Grid Array) packaging technology.
