Low power consumption multiposition three-valued Domino adder

Abstract

The invention discloses a low power consumption multiposition three-valued Domino adder. The adder comprises n-numbered positions of three-valued heat insulation Domino adding units, wherein the k position of three-valued heat insulation Domino adding unit is connected with the low-position carry signal output end of the (k+1) position of three-valued heat insulation Domino adding unit by a heat insulation Domino buffer; the k position of three-valued heat insulation Domino adding unit is also connected with the complementary low-position carry signal output end of the (k+1) position of three-valued heat insulation Domino adding unit by a heat insulation Domino buffer; the ipso position and the signal output end of the j position of three-valued heat insulation Domino adding unit are connected with (n-j)-numbered heat insulation Domino buffers in sequence; the addend signal input end and augend signal input end of the j position of three-valued heat insulation Domino adding unit are connected with (j-1)-numbered heat insulation Domino buffers in sequence; k is equal to 1, 2,......, n-1; j is equal to 1, 2,......, n; and m is equal to 1, 2,......, n-1. The adder has the following advantage: the power consumption is reduced by about 61% compared with that of the conventional three-valued Domino adder adopting the direct-current power source.

Description

technical field [0001] The invention relates to a ternary adder, in particular to a multi-bit ternary low power consumption domino adder. Background technique [0002] The current digital circuit system is mainly implemented by binary logic, and the logic values ​​that can be transmitted by a single signal line are only 0 and 1, and the space and time utilization of the circuit is low. The use of multi-valued logic can greatly reduce the number of circuit input variables and increase the amount of information carried by each connection, thereby reducing the area of ​​the chip and enhancing the data processing capability. Due to its advantages in circuit area and speed, domino circuits are widely used in various high-performance circuits. Therefore, the combination of multi-valued logic and domino circuits can further reduce the circuit area, increase the information density of the circuit, and reduce the circuit cost. . [0003] Addition is the most basic arithmetic operat...

Problems solved by technology

At present, the traditional adder consumes the charge from the power supply to the ground at one time, causing great waste; while the adiabatic adder using the AC pulse power supply can fully recover the charge stored in the circuit node, effectively reducing the power consumption of the circuit
