Impact of Process Variations on Speedup and Maximum Achievable Frequency of Extensible Processors
Mehdi Kamal, Ali Afzali-Kusha, Saeed Safari, Massoud Pedram
Article No.: 19
DOI: 10.1145/2567665

In this article, we investigate the impact of process variations on the speedup and maximum frequency of the extended ISA processor. First, without considering process variations, a custom functional unit (CFU) is designed based on nominal timing...

Design and Evaluation of Technology-Agnostic Heterogeneous Networks-on-Chip
Haera Chung, Christof Teuscher, Partha Pande
Article No.: 20
DOI: 10.1145/2567666

Traditional metal-wire-based networks-on-chip (NoC) suffer from high latency and power dissipation as the system size scales up in the number of cores. This limitation stems from the inherent multihop communication nature of larger NoCs. It has...

Improved Threshold Logic Synthesis Using Implicant-Implicit Algorithms
Ashok Kumar Palaniswamy, Spyros Tragoudas
Article No.: 21
DOI: 10.1145/2597175

Existing threshold logic synthesis methods decompose larger input functions into smaller input functions and perform synthesis for them. It is shown that significantly larger input functions can be synthesized by implementing the existing methods...

Clock-Tree Synthesis with Methodology of Reuse in 3D-IC
Fu-Wei Chen, Tingting Hwang
Article No.: 22
DOI: 10.1145/2567668

IP reuse methodology has been used extensively in SoC (system-on-chip) design. In this reuse methodology, while design and implementation costs are saved, manufacturing cost is not. To further reduce the cost, this reuse concept has been proposed...

On-Chip Hybrid Power Supply System for Wireless Sensor Nodes
Wulong Liu, Yu Wang, Yuchun Ma, Yuan Xie, Huazhong Yang
Article No.: 23
DOI: 10.1145/2492683

With the miniaturization of electronic devices, small-size but high-capacity power supply systems appear to be more and more important. A hybrid power source, which consists of a fuel cell (FC) and a rechargeable battery, has the advantages of...

Interpreting Assays with Control Flow on Digital Microfluidic Biochips
Daniel Grissom, Christopher Curtis, Philip Brisk
Article No.: 24
DOI: 10.1145/2567669

BioCoder is a C++ library developed at Microsoft Research, India, for the unambiguous specification of biochemical assays. This article describes language extensions to BioCoder along with a compiler and runtime system that translate and...

A Fast Extraction Algorithm for Defect-Free Subcrossbar in Nanoelectronic Crossbar
Bo Yuan, Bin Li
Article No.: 25
DOI: 10.1145/2517137

Due to the super scale, high defect density, and per-chip designing paradigm of emerging nanoelectronics, the runtime of the algorithms for defect-tolerant design is of vital importance from the perspective of practicability. In this article, an...

3D vs. 2D Device Simulation of FinFET Logic Gates under PVT Variations
Sourindra M. Chaudhuri, Niraj K. Jha
Article No.: 26
DOI: 10.1145/2567670

Recently, multigate transistors have been gaining attention as an alternative to conventional MOSFETs. Superior gate control over the channel, smaller subthreshold leakage, and reduced susceptibility to process variations are some of the key...
