Soft-Error Characterization and Hardening Trade-offs in Static PCHB Asynchronous Circuits
Ramya Karri, Srija Rasoori, Ashiq A. Sakib
Pre-Charge Half Buffer (PCHB) is a promising asynchronous digital design paradigm for harsh-environment operation; however, its soft-error characteristics remain largely unexplored…
Monolithic 3D Integration for Null Convention Logic (NCL)-Based Asynchronous Circuits
Xiameng Zhang, Kushal Ponugoti, Ashiq Sakib +1
As the demand for high-speed and low-power electronics continues to grow, the quasi-delay-insensitive (QDI) asynchronous domain of digital design has emerged as a promising alterna…
HALOC-AxA: An Area/-Energy-Efficient Approximate Adder for Image Processing Application
Hasnain A. Ziad, Ashiq A. Sakib
The design of approximate adders has been widely researched to advance energy-efficient hardware for computation-intensive multimedia applications, such as image, audio, or video p…
SR-NCL: an Area-/Energy-Efficient Resilient NCL Architecture Based on Selective Redundancy
Hasnain A. Ziad, Alexander C. Bodoh, Ashiq A. Sakib
Duplication-based redundancy schemes have proven to be effective in designing fully-resilient Quasi-delay Insensitive (QDI) asynchronous circuits. The complete resiliency, however,…
