Espressif Systems (Shanghai) Co., Ltd. (Espressif; ) is a publicly listed Chinese semiconductor company headquartered in Shanghai. It focuses on developing and selling wireless microcontroller unit communication chips and modules that are used in internet of things (IoT). History In 2008, Espressif was founded in China by Singaporean national, Teo Swee Ann. Teo who graduated from National University of Singapore with degrees in electrical engineering had worked for Montage Technology as an engineering director. Espressif initially started as one-man consulting firm which later expanded. However due to small quantity of chips commissioned by Espressif, foundries tended to reject it. However TSMC who had heard of Teo's work at Montage Technology gave Espressif a chance and became its supplier. On 22 July 2019, Espressif had its initial public offering and became a listed company on the Shanghai Stock Exchange STAR Market. The offering raised 1.2 billion yuan. In March ...

Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Instruction Set Architecture
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an ''implementation'' of that ISA. In general, an ISA defines the supported instructions, data types, registers, the hardware support for managing main memory, fundamental features (such as the memory consistency, addressing modes, virtual memory), and the input/output model of implementations of the ISA. An ISA specifies the behavior of machine code running on implementations of that ISA in a fashion that does not depend on the characteristics of that implementation, providing binary compatibility between implementations. This enables multiple implementations of an ISA that differ in characteristics such as performance, physical size, and monetary cost (among other things), but t ...

2008 Establishments In China
8 (eight) is the natural number following 7 and preceding 9. Etymology English ''eight'', from Old English '', æhta'', Proto-Germanic ''*ahto'' is a direct continuation of Proto-Indo-European '' *oḱtṓ(w)-'', and as such cognate with Greek and Latin , both of which stems are reflected by the English prefix oct(o)-, as in the ordinal adjective ''octaval'' or ''octavary'', the distributive adjective is ''octonary''. The adjective ''octuple'' (Latin ) may also be used as a noun, meaning "a set of eight items"; the diminutive '' octuplet'' is mostly used to refer to eight siblings delivered in one birth. The Semitic numeral is based on a root ''*θmn-'', whence Akkadian ''smn-'', Arabic ''ṯmn-'', Hebrew ''šmn-'' etc. The Chinese numeral, written (Mandarin: ''bā''; Cantonese: ''baat''), is from Old Chinese ''*priāt-'', ultimately from Sino-Tibetan ''b-r-gyat'' or ''b-g-ryat'' which also yielded Tibetan '' brgyat''. It has been argued that, as the cardinal nu ...

ESP8266
The ESP8266 is a low-cost Wi-Fi microcontroller, with built-in TCP/IP stack, TCP/IP networking software, and microcontroller capability, produced by Espressif Systems in Shanghai, China. The chip was popularized in the English-speaking maker culture, maker community in August 2014 via the ESP-01 module, made by a third-party manufacturer Ai-Thinker. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes command set, Hayes-style commands. However, at first, there was almost no English-language documentation on the chip and the commands it accepted. The very low price and the fact that there were very few external components on the module, which suggested that it could eventually be very inexpensive in volume, attracted many hackers to explore the module, the chip, and the software on it, as well as to translate the Chinese documentation. The ESP8285 is a similar chip with a built-in 1 MiB flash memory, allowing ...

Artificial Intelligence Of Things
The Artificial Intelligence of Things (AIoT) is the combination of artificial intelligence (AI) technologies with the Internet of things (IoT) infrastructure to achieve more efficient IoT operations, improve human-machine interactions and enhance data management and analytics. In 2018, KPMG published a foresight study on the future of AI including scenarios until 2040. The analysts describe a scenario in detail where a community of things would see each device also contain its own AI that could link autonomously to other AIs to, together, perform tasks intelligently. Value creation would be controlled and executed in real-time using swarm intelligence. Many industries could be transformed with the application of swarm intelligence, including: automotive, cloud, medical, military, research, and technology. In the AIoT an important facet is AI being done on some Thing. In its purest form this involves performing the AI on the device, i.e. at the edge or Edge Computing, with no need ...
