Structural and Hardware Complexities of Microprocessor Design According to Moore’s Law

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.

Design and Implementation 4-Bit Quaternary MVL Arithmetic and Logic Unit

“…The major challenges in VLSI design are reducing the area of chip and increasing speed of the circuit. The traditional binary logic faced many problems nowadays such as routing, speed, the number of instructions, power dissipation and silicon area, in addition to the increasing of the number of transistors according to Moore's law [5].…”

“…The hardware solutions taken many considerations like the decreasing number of transistors [5], changing the realization from voltage mode to the current mode [8], pipeline technologies [9] and finally they tried to move from binary to fully multi-valued logic [10].…”
