As application complexity continues to grow we have reached a limit on increasing performance by merely scaling clock speed. To meet the ever-increasing processing demand, modern System-On-Chip solutions contain multiple processing cores. The dilemma is how to map applications to multicore devices. In this paper, the authors present a programming [...]

Specifying and validating embedded systems and chips becomes increasingly challenging as feature sets and non-functional constraints grow. It’s especially difficult when the system involves a multicore programmable platform, which includes several processing engines such as microprocessors, microcontrollers or DSPs, that run application software distributed across the various cores.
The development of the hardware (HW) [...]

Microcontrollers (MCUs) today are amazing examples of synergy and innovation. Anywhere from 30,000 to 2 million gates are contained on a single chip, and up until very recently, the various integrated components and modules were considered advanced ICs on their own.
For example, currently a typical MCU device (Figure 1, below) may contain the [...]

The level of innovation in companies throughout the supply chain has increased significantly in the past few months. Engineers are now turning their attention away from marginal improvements that were designed to keep products coming out in the pipeline to more long-term achievements that can bring a new paradigm to the market.
Many end [...]

“In today’s competitive environment, prototyping is necessary to understand customers, create a new market or attend to what has been ignored by industry leaders. The big problem is that most engineers don’t see the benefits of prototyping and are not convinced that it is an effective way of developing and using a prototype.
This [...]

In then the past few years we have seen multiprocessing systems become more mainstream, in fact most modern personal computer CPU’s now feature symmetric multiprocessing systems (SMP), where multiple instantiations of the same processor share the processing burden of the applications running on the PC.
While SMP’s are quite common today, we typically have not seen [...]

NASA and their contractors were developing the hardware and control algorithms for spacecraft attitude control using control moment gyros (CMGs). We were developing a real-time, hardware-in-the-loop computer simulation that could test and simulate the behavior of the CMGs during typical simulated flights. I was developing the digital software; we had other computer [...]
