Jiangsu Lemote Tech Co., Ltd or Lemote (Chinese: 龙梦; pinyin: lóng mèng; literally "Dragon Dream") is a computer company established as a joint venture between the Jiangsu Menglan Group and the Chinese Institute of Computing Technology, involved in computer hardware and software products, services, and projects.

History

In June 2006, the Jiangsu Menglan Group began a joint venture with the Institute of Computing Technology of the Chinese Academy of Sciences. The venture was named Jiangsu Lemote Tech Co., Ltd. The predecessor organization was the Center of Technology Research and Development of Jiangsu Loongson CPU Industrialization Base.

A computer was announced by Zhang Fuxin, an ICT engineer, who said the purpose of this project was to "provide everyone with a personal computer". The device is intended for low income groups and rural area students.^{[citation needed]}

Hardware

Lemote, with partners, provides integrated circuit design services, helps develop the Loongson series of MIPS-based RISC microprocessors, and builds small form factor computers including network computers and netbooks.

Loongson processors

Main article: Loongson

Loongson (Chinese: 龙芯; pinyin: lóngxīn, academic name: Godson, also called Dragon chip) is a range of MIPS instruction set RISC processors used in all Lemote products. Some Loongsons include on-chip circuits to help resist buffer overflow attacks.

Netbook computers

Yeeloong

The Yeeloong netbook computer is intended to be built on free software from the BIOS upwards, and for this reason is used and recommended by Richard Stallman as of January 23, 2010 and September 2008.

Lemote also collaborated in the development of the Gdium netbook which uses its Loongson MIPS processor.

Desktop computers

Lynloong, all-in-one desktop computer, combined computer and monitor, without keyboard.

Myloong, desktop diskless network computer (NC), without monitor or keyboard.

Fuloong, see below.

Products in development

Hiloong, SOHO and family storage center.^{[citation needed]}

Fuloong 2 series of small desktop computers

The Fuloong 2 series is a desktop computer that costs ¥1,015 Chinese yuan, €100 euros, $131 United States dollars.^{[citation needed]} It ships with two Linux distributions, Debian and Rays Linux, but any other distribution that has a mipsel port can be installed, e.g. Gentoo Linux.
