The software food chain Software has become a ubiquitous part of many products and services, some of which are distributed and used on a massive scale. Think of cloud computing, online banking and the engines for today’s cellphones and cameras. Competition requires that such new products are developed more quickly than ever before and yet […]
The Texas A&M team describes an FPGA embedded system design project intended to assess the technology’s suitability for use in real-time, high-performance applications. The test application is a speech encryption system intended for use in military and high-security environments. The team used a Xilinx Virtex II Pro platform FPGA for the project, and was also […]
The article describes the context and need for embedded operating systems that are more responsive to the power management demands placed on today’s electronic devices. It reviews the design objectives for the two main types of power management, reactive and proactive, and examines how both can be implemented. For system developers designing portable electronic devices, […]
This quarter’s issue leans slightly more toward coverage of incoming technologies than usual. Given the state of the economy around us, it can hardly hurt to look to a better future. At the same time, wise men in these new fields do seem quite keen on bringing us all down to earth. Consider: Professor Andre […]
The article describes how methodologies such as graph-based intelligent testbench automation will help engineers efficiently create verification scenarios and stimuli. This is a powerful way of enhancing advanced verification environments and reducing common verification headaches (e.g., reaching coverage goals). Such strategies can help to free up resources, in terms of time, people and hardware, so […]
Software accounts for more than half the development cost for a complex system-on-chip (SoC) platform at the 45nm process node or below. The availability of fundamental software such as compilers, debuggers, operating systems and industry-specific middleware determines the success or failure of a chip design. In simple terms, if there is little or no software […]
The article describes an algorithm that combines performance and variation objectives in a behavioral model for a given analog circuit topology and process. The tradeoffs between performance and yield are analyzed using a multi-objective evolutionary algorithm and Monte Carlo simulation. The results indicate a signi?cant improvement in overall simulation time and ef? ciency compared to […]
The process of proving the system is working and performing optimally, under all application and environmental conditions, has become too inefficient and difficult for existing methodologies. Traditional methods for addressing post-silicon requirements have reached the point of diminishing returns. What was once an exercise of designing, implementing and verifying 25,000 to 50,000 gates of instrumentation […]
Andre Geim When you were young, did you enjoy bouncing around on a trampoline? If so, try this for size. Imagine a membrane about 275 miles long, one mile deep and an average of 10 miles wide. These dimensions matter. Because this sheet of material covers the entire Grand Canyon—and before you go bouncing on […]
Lane Mason Marc Greenberg DDR3 DRAMs still languish around the edges of the market despite their supposed attraction in terms of power and performance, the widespread availability of product, and the presence of a supposedly ‘evolved’ ecosystem and implementation infrastructure. Just over 18 months ago, Intel launched a major Go To DDR3 market initiative at […]
