RISC-V for ultra-low power processing and AI on the edge

December 3, 2020 By Jeff Shepard

RISC-V is an exciting and rapidly-emerging technology. RISC-V is software; it is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. So far, this FAQ series has looked at how “RISC-V is growing and offers stability, scalability, and security,” the “Growing availability of tools reducing the risk of […]

Growing availability of tools reducing risk of using RISC-V

December 1, 2020 By Jeff Shepard

As discussed at the end of the first FAQ in this series, “RISC-V is growing and offers stability, scalability, and security,” there is a lack of testing standards and tools for RISC-V compared with mature ISAs such as Intel and Arm. This is an area that is experiencing accelerating developments and progress. The growing availability […]

RISC-V is growing and offers stability, scalability and security

November 30, 2020 By Jeff Shepard

RISC-V is growing rapidly. Semico Research has projected that 62.4 billion RISC-V CPU cores will be sold in 2025. While that’s only about 6% of the overall CPU core market, RISC-V is an emerging technology that most designers should follow and become increasingly familiar with. RISC-V is becoming more commercially attractive as a result of […]

Smart grids, software defined grids, and big data

November 24, 2020 By Jeff Shepard

The business models and technology architectures of electric utility grids worldwide are under attack both at the edge and overall. The first FAQ in this series looked at the attack on the edge of the grid in “Nano grids, microgrids and the decentralization of the electric grid.” Virtual power plants, distributed energy resources, and power […]

Virtual power plants, distributed energy resources and power in the cloud

November 24, 2020 By Jeff Shepard

Virtual power plants (VPPs) are increasingly challenging the dominance of traditional large-scale centralized electricity generation. A VPP is defined as a collection of distributed energy resources (DERs) that are aggregated through cloud computing and control for the purpose of providing enhanced power generation and availability. The DERs are often heterogeneous and can include wind power, […]

Nano grids, microgrids, and zero net energy consumption

November 23, 2020 By Jeff Shepard

Electric utility grids around the world are undergoing a fundamental change in architecture. The centralized grid that was designed to provide inexpensive electricity with a reasonable level of quality and reliability is no longer meeting society’s needs. Aging transmission and distribution systems are significantly reducing both the quality and reliability of electricity. And the use […]

Benefits of software-configurable power systems

November 20, 2020 By Jeff Shepard

The first FAQ in this series looked at the various hardware options for implementing digital power. Part two took a deep look at the PMBus/SMBus communication protocol for implementing digital power configuration, control, and monitoring. This FAQ will delve into the system level benefits of using digital power converters with PMBus communication. PMBus can bring […]

Digital power management and PMBus moving into the future

November 19, 2020 By Jeff Shepard

Digital power ICs communicate with each other via the System Management Bus (SMBus) using the Power Management Bus (PMBus) communication protocol and the AVSBus protocol, a subset of the PMBus protocol for implementing adaptive voltage scaling. Using SMBus and PMBus-enabled devices for power conversion provides flexibility and control that is impossible with traditional analog power […]
