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 […]
FAQ
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 […]
What’s the future for RISC-V in 5G?
The versatility of the RISC-V instruction set architecture (ISA) can be seen in the breadth of 5G applications using the technology. Examples include a complete 5G base station system-on-chip (SoC), a 5G small cell distributed unit (DU) SoC, a recurrent neural network (RNN) IC optimized for 5G radio resource management, even handsets are under development […]
Domain specific accelerators for RISC-V
Domain specific accelerators (DSAs) are specialized hardware computing engines optimized for specific tasks. DSAs have been developed for graphics, simulation, image processing, deep learning, bioinformatics, and other tasks. Compared to general purpose processors, accelerators offer orders of magnitude improvements in performance/cost and/or performance/watt. The previous FAQ in this series, “What’s the future for RISC-V in […]
Memory, disk drives, memory fabrics and RISC-V
The unique and flexible computational architecture of RISC-V can be leveraged by designers of massive parallel computational storage solutions, hard disc drives (HDDs) and solid-state disk drives (SSDs), and memory fabric architectures such as Ethernet Bunch of Flash (EBOF) or Just a Bunch of Flash (JBOF) to implement high-performance solutions. This article will look at […]
What is the RISC-V ecosystem?
In its most basic form, RISC-V is an open standard instruction set architecture (ISA) based on reduced instruction set computer (RISC) design principles. RISC-V is an open specification and platform; it is not an open-source processor. All other aspects of the RISC-V ecosystem build on that foundation. The hardware and software in the RISC-V ecosystem […]
Teardown: Playstation 5 DualSense controller
The DualSense wireless controller for the PS5 has several features that come in handy for gaming. Perhaps most interesting is its immersive haptic feedback and adaptive triggers. Dual actuators replace the rumble motors used on previous versions and are designed to simulate the feeling of weapon recoils and numerous other game actions. Also included are […]
RISC-V vs. ARM vs. x86 – What’s the difference?
Many of the differences between RISC-V, ARM, and x86 microprocessors are subtle and relate to how memory is addressed, branches are executed, exceptions are handled, and so on. This article will consider higher-level differences and will briefly compare reduced instruction set computing (RISC) and complex instruction set computing (CISC), consider the impact those differences have […]
Sensor-based automation for smart buildings
Cloud-based intelligence can help serve as a nervous system for controllers handling multiple building domains. Preet Sibia, Power and Sensor Systems, Robert Junker • Infineon The core principle of building automation is the centralized control of a building’s domain, such as HVAC, shading, lighting, access control systems and more. Real-time monitoring of usage patterns and […]
