Zhaoxin
Zhaoxin (Shanghai Zhaoxin Semiconductor Co., Ltd.; , ) is a fabless semiconductor company, created in 2013 as a joint venture between VIA Technologies and the Shanghai Municipal Government. The company manufactures x86-compatible desktop and laptop CPUs. The term '' Zhào xīn'' means ''million core''.In China 兆 can mean either short-scale million (1e6) or trillion (1e12). However, for IT-related topics 兆 always means mega/million in mainland China. The processors are created mainly for the Chinese market: the venture is an attempt to reduce the Chinese dependence on foreign technology. Background ''Zhaoxin'' is a joint venture between VIA Technologies and the Shanghai Municipal Government. In 2021 it was reported that VIA has a 14.75% shareholding in the company. China has a domestic policy to "replace all foreign hardware and software from its public infrastructure with homegrown solutions" by 2023 (the so-called 3–5–2 policy). VIA holds an x86 license which allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VIA Technologies
VIA Technologies, Inc. () is a Taiwanese manufacturer of integrated circuits, mainly motherboard chipsets, CPUs, and memory. It was once the world's largest independent manufacturer of motherboard chipsets. As a fabless semiconductor company, VIA conducts research and development of its chipsets in-house, then subcontracts the actual (silicon) manufacturing to third-party merchant foundries such as TSMC. VIA is also the parent company of VIA Labs Inc. (VLI, ). As an independently traded subsidiary, VLI develops and markets USB 3, USB 4, USB Type-C, and USB PD controllers for computer peripherals and mobile devices. History The company was founded in 1987, in Fremont, California, USA by Cher Wang. In 1992, it was decided to move the headquarters to Taipei, Taiwan in order to establish closer partnerships with the substantial and growing IT manufacturing base in Taiwan and neighbouring China. In 1999, VIA acquired most of Cyrix, then a division of National Semiconductor. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centaur Technology
Centaur Technology was an x86 CPU design company started in 1995 and subsequently a wholly owned subsidiary of VIA Technologies. In 2015, the documentary ''Rise of the Centaur'' covered the early history of the company. The company was broken up in 2021. History Centaur Technologies Inc. was founded in April 1995 by Glenn Henry, Terry Parks, Darius Gaskins, and Al Sato. The funding was provided by Integrated Device Technology, Inc (IDT). The business goal was to develop compatible x86 processors that were less expensive than Intel processors and consumed less power. There were two main elements of the plan: # a new design, developed from scratch, of an x86 processor core optimized differently from Intel's cores; # a novel management approach designed to achieve high productivity. While funded by IDT, three different Centaur designs were shipped under the marketing name of WinChip. In September 1999, Centaur was purchased from IDT by VIA Technologies, a Taiwanese company.

VIA Nano
The VIA Nano (formerly Code name#Commercial code names in the computer industry, code-named VIA Isaiah) is a 64-bit CPU for personal computers. The VIA Nano was released by VIA Technologies in 2008 after five years of development by its CPU division, Centaur Technology. This Isaiah 64-bit architecture was designed from scratch, unveiled on 24 January 2008, and launched on 29 May, including low-voltage variants and the Nano brand name. The processor supports a number of VIA-specific x86 extensions designed to boost efficiency in low-power appliances. History Unlike Intel and AMD, VIA uses two distinct development code names for each of its CPU cores. In this case, the codename 'CN' was used in the United States by Centaur Technology. Biblical names are used as codes by VIA in Taiwan, and Isaiah was the choice for this particular processor and architecture. It is expected that the VIA Isaiah will be twice as fast in integer performance and four times as fast in floating-point p ...

VIA Isaiah
Isaiah ( or ; , ''Yəšaʿyāhū'', "Yahweh is salvation"; also known as Isaias or Esaias from ) was the 8th-century BC Israelite prophet after whom the Book of Isaiah is named. The text of the Book of Isaiah refers to Isaiah as "the prophet", but the exact relationship between the Book of Isaiah and the actual prophet Isaiah is complicated. The traditional view is that all 66 chapters of the book of Isaiah were written by one man, Isaiah, possibly in two periods between 740 BC and 686 BC, separated by approximately 15 years. Another widely held view suggests that parts of the first half of the book (chapters 1–39) originated with the historical prophet, interspersed with prose commentaries written in the time of King Josiah 100 years later, and that the remainder of the book dates from immediately before and immediately after the end of the 6th-century BC exile in Babylon (almost two centuries after the time of the historical prophet), and that perhaps these later cha ...

SM4 (cipher)
ShāngMì 4 (SM4, 商密4) (formerly SMS4) is a block cipher, standardised for commercial cryptography in China. It is used in the Chinese National Standard for Wireless LAN WAPI (WLAN Authentication and Privacy Infrastructure), and with Transport Layer Security. SM4 was a cipher proposed for the IEEE 802.11i standard, but it has so far been rejected. One of the reasons for the rejection has been opposition to the WAPI fast-track proposal by the IEEE. SM4 was published as in 2021. The SM4 algorithm was drafted by Data Assurance & Communication Security Center, Chinese Academy of Sciences (CAS), and Commercial Cryptography Testing Center, National Cryptography Administration. It is mainly developed by Lü Shuwang ( zh, 吕述望). The algorithm was declassified in January, 2006, and it became a national standard (GB/T 32907-2016) in August 2016.Lu Shuwang.

GNU Compiler Collection
The GNU Compiler Collection (GCC) is a collection of compilers from the GNU Project that support various programming languages, Computer architecture, hardware architectures, and operating systems. The Free Software Foundation (FSF) distributes GCC as free software under the GNU General Public License (GNU GPL). GCC is a key component of the GNU toolchain which is used for most projects related to GNU and the Linux kernel. With roughly 15 million lines of code in 2019, GCC is one of the largest free programs in existence. It has played an important role in the growth of free software, as both a tool and an example. When it was first released in 1987 by Richard Stallman, GCC 1.0 was named the GNU C Compiler since it only handled the C (programming language), C programming language. It was extended to compile C++ in December of that year. Compiler#Front end, Front ends were later developed for Objective-C, Objective-C++, Fortran, Ada (programming language), Ada, Go (programming la ...
