Download and read online ebook Designing Asynchronous Circuits using NULL Convention Logic (NCL) write by Scott Smith. This book was released on 2022-06-01. Designing Asynchronous Circuits using NULL Convention Logic (NCL) available in PDF, EPUB and Kindle. Designing Asynchronous Circuits using NULL Convention Logic (NCL) begins with an introduction to asynchronous (clockless) logic in general, and then focuses on delay-insensitive asynchronous logic design using the NCL paradigm. The book details design of input-complete and observable dual-rail and quad-rail combinational circuits, and then discusses implementation of sequential circuits, which require datapath feedback. Next, throughput optimization techniques are presented, including pipelining, embedding registration, early completion, and NULL cycle reduction. Subsequently, low-power design techniques, such as wavefront steering and Multi-Threshold CMOS (MTCMOS) for NCL, are discussed. The book culminates with a comprehensive design example of an optimized Greatest Common Divisor circuit. Readers should have prior knowledge of basic logic design concepts, such as Boolean algebra and Karnaugh maps. After studying this book, readers should have a good understanding of the differences between asynchronous and synchronous circuits, and should be able to design arbitrary NCL circuits, optimized for area, throughput, and power.

Design and Implementation of an Asynchronous NULL Convention Logic (NCL) FPGA available in PDF, EPUB and Kindle. "This Master's thesis outlines the design of a completely asynchronous Field Programmable Gate Array (FPGA) for implementing NULL Convention Logic (NCL) digital circuits. The proposed design uses four Configurable Logic Blocks (CLB), each of which in turn is designed using four Logic Elements (LE) to implement NCL logic function. Each LE can be configured to function as any one of the 27 fundamental NCL gates. A Logic Element is designed by concatenating a Look-Up-Table (LUT) with a pull-up pull-down transistor chain and a hysteresis loop. The interconnections and the switch box are designed using pass transistors and SRAM. In this thesis, a 4-input Look-Up Table (LUT) based 16-gate FPGA specifically for NCL circuits was designed and successfully programmed as a dual-rail non-pipelined 4-bit NCL register. The design was first created using the schematic capture, followed by layout or the physical level designs subsequent to successful simulation. The NCL FPGA is simulated at the transistor level using the 1.8V, 180nm TSMC CMOS process. The size of FPGAs is now more than 1 million equivalent gates, making them a viable alternative to custom design for all but the most complex processors. FPGAs are relatively low-cost and are reconfigurable, making them perfect for prototyping, as well as implementing the final design, especially for low volume production. To compete with this cheap, reconfigurable synchronous implementation, an NCL-specific FPGA is needed, such that NCL circuits can be implemented without necessitating a prohibitively expensive full-custom design"--Abstract, leaf iii.
