You have not seen the domestic CPU: probably the most complete series chip Godson family tree (on)
https://www.ijiwei.com/html/news/newsdetail?source=pc&news_id=717788
In 2009, the famous American magazine "connect" published a story entitled "The People's processors," the report reads:
Imagine a country needs to rely entirely on imports of certain precious goods from countries with which a conflict or war with unstable economic exchanges, and, if no such commodity, the whole society will be forced to halt. The country is China, the country with which the United States has a war conflict, and this product is the CPU.
Imagine that your nation is entirely dependent on a belligerent and economically unstable foreign country for a precious commodity. Imagine that without that commodity, your entire society would grind to a halt. Got it? OK, now imagine that your nation is China, the belligerent nation is the US, and the commodity is CPUs.
China is a big country, must have their own processor. As a representative of the domestic product of general-purpose processor, Godson from 2001 to the present has been developed for 18 years, developed Godson-1, No. 2, No. 3 three processors, and processor Godson office in government, and military, industrial control, military, aerospace and many other fields have been widely used. But the mainstream and X86, ARM processor compared Godson is still not well familiar with.
In 18 years Godson development, the companies have developed what Godson processor? What is the history of their development, the performance is like? Currently, both the White Paper Godson, academic journals, or a variety of media, do not have this detail. In this article, we will attempt to open a document based on a variety of Godson processor family of processors to do a detailed introduction.
Godson processors according to their structure, divided into four categories, namely, single emitter 32 (132), a dual emission 32 (232), four 64-bit transmit (464) and dual 64-bit transmit (264). In accordance with the performance of the processor, the number of core divided into small Godson CPU 1, the CPU and Godson Godson 3 large CPU 2.
1. Godson-1 series
Godson-1 processor can be roughly divided into two categories, one is a single 32-bit CPU transmitted using GS132 series processor core, a single emission frequency is performed in the order of about 10MHz, as the main MCU; one is bis CPU 32 transmitted using GS232 series processor core, dual emission frequency is out of order several hundreds MHz, higher performance can be used as embedded processors, ARM processors replace the same frequency. In 2008, Godson was ready to cut nuclear GS132, GS232 and GS464 focus on R & D processor cores. But later, or continue the GS132 Godson processor core research and development, based on this CPU core has developed a series of low-end processors.
1.1 Godson 1
Godson-1 started to develop in 2000, 2001, August 19 Godson-1 Logic design running on the FPGA platform. Therefore, August 19 was designated as the Godson's birthday. Godson physical design there are three versions 1, A program designed by a third party commissioned Godson, B program flow sheet of an experimental program, C programs for program production. 2002 August 10, Godson-1 (A program) light up the operating system successfully, August 29 Godson (C program) 1 successfully boot the operating system.
Godson a 0.18 micron CMOS process flow sheet, clocked at 266MHz, single emitter 32, the transistor chip 4,000,000. Class using the MIPS III RISC instruction set, with dynamic pipeline seven, integer unit 32 and floating point unit 64. The overall performance is lower than Intel Pentium II. To commemorate Mr. Su Pei mentor Weiwu in the 50th anniversary of the computer business, "Godson" was named "Summer 50."

2. Godson-2 series
龙芯2号处理器都是64位处理器，早期的型号是4发射乱序执行的64位GS464系列处理器核，后来新出的处理器升级为采用GS464E处理器核。龙芯2K处理器是双发射乱序执行的GS264处理器核的64位双核处理器。龙芯2GQ则是一款4核处理器。
2.1 龙芯2A/2B
龙芯2号的设计从2002年7月开始，采用4发射和乱序执行结构的设计，64位设计，7～10级流水线。
龙芯2号的寄存器堆设计有两个方案，A方案采用商用寄存器堆，在台积电流片；B方案采用微电子中心设计的寄存器堆，在中芯国际流片。
A方案采用的商用寄存器堆设计出错,导致流片失败。B方案流片成功，2003年10月17日成功启动操作系统，最高频率为300MHz，功耗1W—2W。相同主频下，龙芯2B的性能已经超过了Pentium II，是龙芯1号的3～5倍。
为了纪念毛主席诞辰110周年，龙芯2B代号MZD110。龙芯2号的性能是之前研制成功的龙芯1号的3倍，超过了相同主频的奔腾II的性能。

2.2 龙芯2C
龙芯2C是龙芯2B的优化版本。在上海中芯国际(SMIC)利用0.18微米CMOS工艺进行了多次成功流片,2004年9月28日流片成功，定型芯片主频为500MHz。龙芯2C的性能是之前研制成功的龙芯2B性能的3倍，达到了相同主频的奔腾III的性能。为了纪念邓小平诞辰100年，龙芯2C的代号为DXP-100。
龙芯2C，代号DXP-100▲
2.3 龙芯2D
根据龙芯处理器的早期发展历史，基本上每年有一款处理器流片。由于龙芯2C在2004年流片，而龙芯2E于2006年流片，可以推测龙芯2D应该是在2005年流片的产品。在中科院微电子所的黄令仪研究员的回忆文章中，提到了她参与了龙芯2D的物理设计。
在《龙芯的足迹》中《2006年回顾及2007年展望》一文中，胡伟武说“2005年我们面临的严峻形势赋予龙芯2E背水一战的悲壮色彩”，因此可以推测龙芯2D极有可能是一个流片失败的型号，或者是一个中途被放弃的型号。
2.4 龙芯2E
Godson 2E delivery taped at the end of November 2005, 18 March 2006 silicon success.
2006 September 13 to the 70th anniversary of the victory of the Long March 2E named Godson CZ70 the organization by the Ministry of Science, Science and Technology Minister Xu Guanhua when he personally participated in the inspection. Godson 2E is mainland China's first 90nm processor design, the number of transistors 47 million, the highest frequency up to 1GHz. Godson-2E chip area 6.8mm * 5.2mm, only Intel Pentium 4 1/4. Godson 2E prototype Found SPEC CPU2000 point score of 503 points and 503 points floating point, double precision floating point maximum speed 3.99GFlops. Godson 2E is three times the performance of Godson 2C, reaching the level of affordable Intel Pentium IV processor. Godson 2E optimize the design process, STMicroelectronics has cooperated with the Godson.
Based on the success of Godson 2E, STMicroelectronics also spent over three million dollars to buy a license fee Godson production and marketing authorization 2E / 2F, creating a core of computer technology for licensing precedent.
Due to the use of Northbridge Godson 2E FPGA implementation, high cost, the processor is no large-scale production.
