Embedded computing is currently enjoying a rebirth thanks to a technology called virtualization. It started when Imagination became the first semiconductor IP company to introduce virtualization to microcontroller-type CPUs and then demonstrated how developers could take advantage of this feature by using a lightweight hypervisor optimized for MIPS M-class MCUs. We then showed how the same virtualization technology can be

In a previous article I described the basic concepts of computer virtualization and how the MIPS architecture efficiently implements hardware virtualization. This article will focus on multithreading in an attempt to define what it is, and why it’s useful. A thread is a sequence of instructions. Multithreading refers to the ability of a given processor (e.g. CPU, GPU, etc.) to

When we originally introduced the Ensigma Series4 RPU family, we mainly focused on the support for different connectivity standards such as Wi-Fi and Bluetooth. However, there were also several mentions of the Ensigma’s capability to support broadcast TV and radio standards. In this two part article, I would like to reveal some details about a next generation broadcast TV standard

To render images at interactive framerates, engines have to approximate the behavior of real world phenomena – such as shadows – rather than simulating them. As real time rendering techniques continue to push towards photorealism, the cost of these approximations approaches the point of diminishing returns. Although traditionally seen as a complex offline process, ray tracing is becoming an increasingly

With the Wi-Fi Alliance launch of the second generation of the 802.11ac certification program, the Wi-Fi industry has taken another huge step forward in increasing the speed of Wi-Fi – and more importantly a big step in improving the efficiency of Wi-Fi networks. When it was officially approved in 2014, the IEEE 802.11ac standard introduced a number of features that

We’ve mentioned in a recent blog post how maintaining presence is key in virtual reality systems. Rendering applications at high framerates (60, 90 or 120 Hz depending on the Head Mounted Display’s maximum refresh rate) with low motion-to-photon latency is an important part of achieving it. In this article, I’ll explain how the OVR_multiview extension can be used to reduce

The Internet of Things is a fast-growing industry built on the promise of ubiquitous connectivity that will enable billions of devices to talk to each other and to people. The estimates for the number of IoT devices to ship by 2020 can vary widely, from the more conservative six billion figure presented by the Linley Group to the breath-taking 200

When we think of the IoT market, most of us imagine a homogenized architecture where anything and everything is connected to the internet and to each other. The reality however is that the multiple IoT ecosystems emerging recently have had very different requirements, creating a fragmentation of the IoT industry that is affecting everyone in the manufacturing supply chain. Several

According to the latest data published by the World Health Organization (WHO), there were 1.25 million road traffic deaths globally in 2013. More than 36,000 people have lost their life in the United States due to car accidents; the numbers paint an even more unfortunate picture for China and India: both countries have registered more than 200,000 road traffic-related deaths.

Back in March 2015, the Federal Communications Commission (FCC) – a government agency tasked with regulating interstate communications in the United States – issued a security document that included a series of provisions related to the use of wireless devices that operate in the U-NII radio bands. In essence, the FCC wanted the manufacturers of routers and other networking equipment
