Abstract

According to the Moore's law, the number of transistor should be doubled every 18 to 24 months. The main factors of increasing the number of transistor are: a density and a die size. Each of them has a serious physical limitation; the first one "density" may be reached "Zero" after few years, which causes limitation in performance and speed of a microprocessor, the second one "die size" cannot be increased every 2 years, it must be fixed for several years, otherwise it will affect the economical side. This article aims to increase the number of transistors, which increase the performance and the speed of the microprocessor without or with a little bit increasing the die size, by constructing a two-layer crystal square for transistors, which allows increasing the number of transistors two additional times. By applying the new approach the number of transistors in a single chip will be approximately doubled every 24 months according to Moore's Law without changing rapidly the size of a chip (length and width), only the height of a chip must be changed for putting the two layers.

Abstract

The most important factors of the microprocessors' development are improvement in the performance and increasing the speed of a microprocessor. Increasing the performance and the speed of a microprocessor majorly depends on the increasing of the number of transistors on a chip, which causes rapidly growing of microprocessor design complexity. The number of transistors should be doubled every 18-24 months related to Moore's Law. The doubling of transistor count affects increasing of the microprocessor design complexities (such as structural, hardware), raising power dissipation, and cost of design effort. This article presents a proposal to discuss the matter of scaling structural and hardware complexities of a microprocessor design related to Moore's Law. The structural and hardware complexities measurements are presented based on the discussion.

Keywords
