To minimize power consumption, we can reduce f d, CL or Vdd. Many researchers have been studying low power/ low voltage design techniques. For example, research is being conducted in low power DRAM and SRAM design. Also aggressive supply voltage scaling and pro-cess optimization are used for power consumption reduc-
The Arithmetic and Logic Unit (ALU) is a combination circuit that performs a number of arithmetic and logical operations. Over the past two decades, Complementary Metal Oxide Semiconductor (CMOS) technology has played important role in designing high performance systems because of the advantages that CMOS provides: an exceptionally low power-delay product, the ability to
Advances in computer architecture over the past two decades have allowed the performance of digital computer hardware to continue its exponential growth, despite increasing technological difficulty in speed improvement at the circuit level.

We describe four types of adder: the serial adder, the carry-ripple adder, the parallel-prefix adder, and the carry-select adder.The serial adder is the simplest possible adder. The core of the adder consists of the most fundamental unit in addition and, indeed, all computer arithmetic—the full adder, a unit for the addition of two bits.The serial adder exemplifies the

A novel algorithm is presented that assigns codes to instructions during instruction code compression in order to minimize bus-related bit-toggling and thus reduce power consumption and it is shown that high compression ratios do not necessarily result in the lowest power consumption. We present a novel algorithm that assigns codes to instructions during

It was found that most low-power research is concentrated on components research: better batteries with more power per unit weight and volume; low-power CPUs; very low-power radio transceivers; low-power displays. We found that there is very little systems research on low-power systems.

Number Representation and Computer Arithmetic (B. Parhami / UCSB) 5 In a k-digit radix-r number system, natural numbers from 0 to rk – 1 can be represented. Conversely, given a desired representation range [0, M – 1], the required number k of digits in radix r is obtained from the following equation: k = ⎡log r M⎤ = ⎣log r(M – 1)⎦ + 1 (2)
