Peripheral Component Interconnect Express (PCIe) is more than just a high-speed serial bus that’s widely used in computers. PCIe is also found in some embedded systems and is a cost-effective, high performance, reliable, low-latency, and low power bus that can rapidly transfer data directly between PCIe-connected devices. PCIe-connected devices are typically CPUs, GPUs, FPGAs, PCIe-connected […]
FAQ
Applications and algorithms for quantum computing
Developing the hardware for quantum computing and hybrid quantum/classical computing systems is only one step in developing practical quantum computing solutions. Development of quantum algorithms and related software programming of the qubits is required to implement practical applications using quantum approaches to computing. Earlier FAQs in this series looked at the basics of quantum computing, […]
Merging quantum and classical computing in a hybrid system
Practical quantum computing requires connections to the outside world. Those connections may be for collaboration between a quantum computer and an external computing resource such as a supercomputer. They can simply output the results of the quantum computations in a manner accessible and usable by human operators. In either case, there’s a paradox between the […]
Quantum computing system architectures
There are a variety of possible physical embodiments of quantum computers. This FAQ will explore several of those possibilities. Qubits, Hamiltonians, and decoherence are three important concepts needed when discussing various approaches to quantum computing. Check out the first FAQ in this series for a more detailed discussion of “What are the basics of quantum […]
What are the basics of quantum computing?
The concept of quantum computing has been around since the early 1980s when physicist Paul Benioff proposed a quantum mechanical model of the Turing machine. Benioff’s ideas were built upon by Richard Feynman, Yuri Manin, and others, who suggested that a quantum computer had the potential to simulate things that can’t be done using classical […]
Mioty LPWAN – what’s it good for?
Mioty (pronounced “My IoT”) is targeting a wide range of potential application spaces for its low power wide area network (LPWAN) technology. In several cases, it’s intending to supplement or even supplant existing protocols such as WiFi and LoRa, even Ethernet. Mioty is a standardized software-based massive IoT connectivity solution operating in the license-free spectrum. […]
How does mioty compare with other flavors of LPWAN?
Mioty (pronounced “My IoT”) offers designers of low power wide area network (LPWAN) devices and networks another set of performance tradeoffs. This FAQ will start with an overview of four examples of technical approaches to ultra-narrowband (UNB) transmission interfaces, including: triple diversity UNB (3D-UNB), telegram splitting UNB (TS-UNB), dynamic download UNB (DD-UNB), and Lfour. It […]
What is mioty telegram splitting LPWAN?
Mioty (pronounced “My IoT”) is the latest contender in the increasing-crowded field of low power wide area network (LPWAN) offerings. According to the mioty website: “With its best-in-class reliability and scalability, mioty is designed for massive industrial and commercial IoT deployments.” Quite a goal. But with founders including Texas Instruments, Fraunhofer Institute for Integrated Circuits […]
Teardown: Inside a video greeting card
For around $60, you can send a greeting card that incorporates a video. When the recipient opens the card, it can automatically play a video loop that you can upload. The card charges via a USB connection which also allows you to upload the video. Specs for cards we’ve seen typically mention a 2G memory, […]
How does RISC-V fit into automotive systems?
RISC-V is being used in a surprising range of automotive systems ranging from ASIL-D safety rated controllers and security co-processors, artificial intelligence (AI) accelerators, controllers for advanced electric vehicle (EV) battery chargers based on gallium-nitride (GaN) power semiconductors, and even in high-voltage monolithic motor drive controllers for light EVs. The following is a sampling of […]
