We are given plenty of reasons why we ‘should’ all buy electric cars. They will safeguard the environment. They will enhance national security by reducing our dependence on foreign oil. They will create a Detroit 2.0 that can pay back the taxpayer. What we do not hear is a more free-market economic argument. “And the […]
The increasing capability and performance of microcontrollers suggests that they can now reach markets for which they were never previously envisioned, particularly as 32-bit devices move into the mainstream. However, prototyping and even researching new application spaces is difficult with existing tools. These are highly optimized for existing uses, but as such very unwieldy when […]
To the world at large, Junot Diaz is well on the way to becoming a literary superstar. His novel The Brief Wondrous Life of Oscar Wao has already earned critical superlatives and the 2008 Pulitzer Prize for Literature. And deservedly so. It is a fabulous, accessible book, expressed in language that—when you buy a copy […]
Until recently, operating system (OS) specification for embedded systems has been seen largely as an ‘either/or’ exercise. Similarly, OSs that have their foundations in the embedded market and those that have grown out of desktop computers have been seen as competing rather than complementary technologies. Cost and performance criteria within specifications will often lead to […]
Netronome offers a range of programmable Network Flow Processors, which deliver high-performance packet processing and are aimed at designers of communications equipment whose requirements extend beyond simple forwarding. Many network processors and multicore CPUs lack L4-L7 programmability or cannot scale to 10Gbit/s and beyond. Netronome’s flow processors are powered by 40 programmable networking cores that […]
New separation kernels and embedded hypervisors can help ease the pain of migrating legacy systems to new hardware platforms, including multicore processing systems. Bringing multiple OSs and applications on to the same hardware also opens up new possibilities for combining systems that offer real-time performance within a familiar GUI environment. The LynxSecure separation kernel and […]
Universal Serial Bus (USB) is a connectivity specification that provides ease-of-use, expandability and good performance for the end-user. It is one of the most successful interconnects in computer history. Originally released in 1995 for PCs, it now is expanding into use by embedded systems and is replacing older interfaces such as serial and parallel interfaces […]
Semiconductor vendors face increasing demands to lower power consumption. This trend has intensified in the last couple of years with the rejuvenation of the ‘green’ movement. In response, the industry has been getting smarter about low-voltage design, current-saving techniques for both the circuit and process levels, and coordinated power management. Meanwhile, programmers are concentrating on […]
The 2009 Embedded World conference and exhibition in Nuremberg, Germany (March 3-5) has managed to maintain much of its scale despite the global downturn. Some speakers have apparently been pulled out by their companies—the most notable contingent, sadly, coming from the USA—but overall the exhibition has expanded by 5% in terms of its physical size […]
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, […]
