This paper presents a low-power 11-bit 1-MS/s successive approximation register (SAR) analog-to-digital converter (ADC) that uses a self-dithering technique. The LSBs is employed as a dither to improve the resolution. Compared to converters that use the conventional dithering architecture, simulation results show that the proposed self-dithering technique improve the DNL performance with simplified...
Thanks to the improvements in semiconductor technologies, extreme-scale systems such as teradevices (i.e., composed by 1000 billion of transistors) will enable systems with 1000+ general purpose cores per chip, probably by 2020. Three major challenges have been identified: programmability, manageable architecture design, and reliability. TERAFLUX is a Future and Emerging Technology (FET) large-scale...
We present the architecture and design of a general purpose robotics development kit, called X10ABOT, which aims to facilitate the rapid development of robotic solutions to a wide variety of problems. Robotics kits of this sort are usually aimed at casual hobbyists and children, and as a result, usually have severe limitations in the number of sensors and actuators that they can manage. In contrast,...
We attempt to provide an architectural support for fast and efficient bounds checking for multithread work-loads in chip-multiprocessor (CMP) environments. Bounds information sharing and smart tagging help to perform bounds checking more effectively utilizing the characteristics of a pointer. Also, the BCache architecture allows fast access to the bounds information. Simulation results show that the...
A project-oriented course for advanced undergraduate and graduate students is described for simulating multiple processor cores. Simics, a free simulator for academia, was utilized to enable students to explore computer architecture, operating systems, and hardware/software cosimulation. Motivation for including this course in the curriculum is provided along with a detailed syllabus and an assessment...
The performance of a software system has been a major concern of the information technology services industry since its inception in the early 1960's. Up to now, simulation has been a key technique for gaining an understanding of the performance characteristics of the system during development time, while software tools, possibly together with manual operations, have been used to monitor some performance...
