NULL Convention Logic (NCL)

Abstract

"This thesis focuses on design and characterization of arithmetic circuits, such as multipliers and ALUs, using the asynchronous delay-insensitive NULL Convention Logic (NCL) paradigm. This work helps to build a library of reusable components to aid in the integration of asynchronous design paradigms, like NCL, into the semiconductor design industry.

A number of 4-bit x 4-bit unsigned multipliers are designed and characterized in terms of speed and area. The architectures under consideration are bit-serial, iterative, and fully parallel multiplication. The bit-serial and iterative multipliers are developed in the dual-rail domain, while the fully parallel architecture is designed in the quad-rail domain and compared to its equivalent dual-rail version, which was developed previously.

Furthermore, a number of 4-bit, 8-operation parallel arithmetic logic units (ALUs) are designed in the quad-rail domain, and are characterized in terms of speed and area. These versions include a non-pipelined design, an optimally pipelined design, a non- pipelined design utilizing NULL Cycle Reduction (NCR), a non-pipelined design with embedded registration, and a NULL Cycle Reduced non-pipelined design with embedded registration. Applying NCR to either non-pipelined quad-rail ALU significantly increases throughput compared to directly pipelining the ALU, while requiring approximately the same area. These quad-rail versions are then compared to their respective previously developed dual-rail counterparts"--Abstract, page iii.
