Energy Micro

Energy Micro AS was a Norwegian fabless semiconductor company specializing in 32-bit RISC ARM chips now owned by Silicon Labs. The company focuses on ultra low energy consumption MCUs, SoC radios and RF Transceiver. Its EFM32 microcontroller families are based on the ARM Cortex-M0 or M3 processor core with a feature set for low power operation.

History

Energy Micro was founded in 2007. The team consists of semiconductor experienced personnel where the President and CEO Geir Førre previously founded Chipcon, now a subsidiary of Texas Instruments. Co-founder and CTO Øyvind Janbu has experience from Chipcon, Texas Instruments, and Tandberg. Co-founder and the VP of Engineering, Eirik Jørgensen, has previously worked for Atmel. Co-founder and VP of Sales Operation, John Fjellheim, previously worked for Chipcon. In addition to the original founders the following individuals are now part of Energy Micro's management team; Andreas Koller joined from Texas Instruments as the VP of Worldwide Sales and Marketing, Zalina Shaher joined as the VP of Operations and she has former experience from Motorola and Silicon Laboratories, while Phi Hong joined as the VP of Finance.

USB 3.0

USB 3.0 (renamed to USB 3.1 Gen 1 in 2015) is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer mode SuperSpeed (SS) that can transfer data at up to 5 Gbit/s (625 MB/s), which is about ten times faster than the USB 2.0 standard. USB 3.0 connectors are usually distinguished from their USB 2.0 counterparts by blue color-coding of the receptacles and plugs, and the initials SS.

A successor standard, USB 3.1 (renamed to USB 3.1 Gen 2 in 2015), was released in July 2013 with the new transfer mode SuperSpeed+ that can transfer data at up to 10 Gbit/s (1.25 GB/s, twice the rate of USB 3.0), bringing its theoretical maximum speed on par with the first version of the Thunderbolt interface.

Overview

The USB 3.0 specification is similar to USB 2.0 but with many improvements and an alternative implementation. Earlier USB concepts like endpoints and four transfer types (bulk, control, isochronous and interrupt) are preserved but the protocol and electrical interface are different. The specification defines a physically separate channel to carry USB 3.0 traffic. The changes in this specification make improvements in the following areas:

Micro

Micro or Mikro, from the Greek μικρός (mikrós), means "small". It can be used to indicate a smaller than average scale (microscopic scale), as opposed to prefixes mega and macro, which can be used to indicate a larger than average scale.

Micro may refer to:

Energy

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.

Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.

Home theater

A home theater or home theatre is a theater built in a home, designed to mimic (or exceed) commercial theater performance and feeling, more commonly known as a home cinema. Today, home cinema implies a real "cinema experience" at a private home.
