A View from the Top: A Virtual Prototyping Blog

Closing the Loop with Key Performance Indicators In Software Modeling Goes Mainstream, Ed Sperling recently wrote how chipmakers are applying use case modeling techniques to better understand the interactions between software and hardware and how they impact system performance and energy efficiency. As the software content for multicore SoCs grows, these interactions are becoming increasingly […]

Best Practices in Architecture Modeling using TLM-2.0 AT with Fast Timed Extensions Unlike the loosely timed models used for software development, which rely on a high level of abstraction to simulate as fast as possible, the communication between the architecture models in a virtual prototype for early performance analysis requires timing to be modeled more […]

While I am not much of a golf player, I participated in a golf tournament over the summer. It was a very friendly setup with teams of four playing against each other. Each player of the team hits his ball, and the ball that lands in the best position determines the starting point for every […]

If you’re deep into the details, it can be hard to see the bigger picture of what lies ahead. There is a saying for this, of course, which everyone knows: “He can’t see the forest for the trees.” So the solution is to rise above the trees to gain a better view. Interestingly, many benefits […]

In this month’s blog we continue our discussion of power management, specifically looking at how architects can improve the energy efficiency of their SoC as it uses system memory. In March we teamed up with Micron, a global supplier of high performance, low power memory technologies, to present a tutorial at SNUG Silicon Valley (see […]

In this blog we tend to focus on the benefits and opportunities that arise when using virtual prototyping. However, in real life we well know that any situation bears not only opportunities but also risks. I was reminded of this by the recent earthquake disaster in Kumamoto Japan. Having lived in the most earthquake prone […]

Power management. If you’re responsible for the design of low-power, energy-efficient electronic systems and SoCs, you need to have a power management strategy and you need to know as soon as possible if it will meet the demands of your product and its target applications. For example, dynamic voltage and frequency scaling (DVFS) is a […]

Wikipedia describes ADAS (advanced driver assistance systems) as systems developed to automate/adapt/enhance vehicle systems for safety and better driving. Safety features are designed to avoid collisions and accidents by offering technologies that alert the driver to potential problems, or to avoid collisions by implementing safeguards and taking over control of the vehicle. Adaptive features may automate […]

There is something compelling about arriving at the end of the year and reviewing what happened during the year. In principle nothing is really different and a date is just a date, but we humans created this sense of time through well-defined boundaries of hours, days, months and years and a year-end boundary is an […]

End-to-end prototyping to the rescue In this blog I have been discussing the increasing impact of software on many aspects of our lives. In the past we mostly interacted with a software-driven device when we sat in front of a desktop computer. We now carry a device with us that is as powerful as a […]
