Name of Project: Designing Quad-Core Loongson-3 ProcessorSource of Project: Key project supported by 863 Program advanced by the Ministry of Science and Technology& Person in Charge: Hu Weiwu
Project Profile:& The target of the project is to develop high performance computer, server and high end desktop application oriented quad-core Loongson general purpose CPU chip (hereinafter referred to as Loongson-3) and prototype system, with a basic frequency of 1.0GHz, power consumption lower than 15 watts, and production cost within USD 100. The SPEC CPU2000 value and the SPEC CPU2000 rate value of the prototype shall reach 550 and exceed 25 respectively. Besides, in the project, the quad-core general purpose chip developed by ICT will be used as computational node in “High Performance Computer and Grid Service Environment”, a key project under 863 Program.& Loongson-3 adopts 65nm technology in its design. The main specifications of the chip and prototype are as follows:(1)64-digit 4-issue core, the main frequency of each core being above 1GHz;(2)4 processor cores, 4MB level 2 Cache, 2 DDR2 memory controllers, 1-2 HT high speed IO controller and other necessary interface logic are in (3)EEC check or odd-even check is realized for the major data path to enh (4)Based on actual measurement, the highest power consumption upon full-load running of the chip is lower than 15 (5)The cost for chip production after mass production is not higher than USD 100;(6)The SPEC CPU2000 value of the prototype system under 1-core running reaches 550, and the SPEC CPU2000 Rate value under 4-core running is above 25.
Major scope of research covers the following: (1)Architecture and Logic Design& Loongson-3 adopts adjustable 2-dimensional mesh interconnection structure, with an 8*8 crossbar connecting the 4 processors and four-individual-processor shared Level 2 Cache at each node, and the node is connected with other nodes in 4 directions. The Level 2 Cache in the chip of Loognson-3 is located in different nodes, and is shared by all processors. By supporting the major features of X86 instruction system, Loognson-3 enables high-efficiency translation from X86 program to MIPS program and it is compatible with X86.& (2)Design for Test & The Design for Test of Loongson-3 includes design for full scan test of standard unit logic, BIST test of RAM unit, JTAG test of PAD, function test via Scan Collar, redundancy design for the RAM of Level 2 Cache, and redundancy design of RAM of Level 2 Cache, and so on. (3)Function Verification& The Function verification of Loognson-3 includes function verification of the core of the processor, module level simulation, all-system simulation, FPGA verification on partial scale, and so on.& (4)Physical Design& Loongson-3 will adopt 65nm technology in its design. Fully customized design module includes multi-port register file, CAM module, phy used for HT and high speed IO, etc. IP based design and hierarchical design are applied in combination to simplify the physical design of Loognson-3.(5)Prototype System Design& The prototype system design involves hardware design and software design. Hardware design includes the verification of system main board and
while the software design includes transplanting and developing BIOS, operation system, virtual machine, etc.&

1、“AMD Athlon(TM)II X4 641 Quad-Core Processor2.80 GHz”这是一个型号的cpu的完整表述。2、分解释义：①“AMD”是指美国超微半导体公司（Advanced Micro Devices，缩写为“AMD”），即是研发这枚cpu的公司；②“Athlon”是这个cpu的产品系列名，对应的中文名是“速龙”；③“（TM）”是商标标志，在中国“TM”表示已申请但在异议期，而“（R）”是已申请且已通过的商标标志，即“注册商标”，放到这里就是说“速龙”这个系列名已经提交申请，但是还在异议期，即“速龙”不是具有独占性的注册商标名；④“II”这是两个大写的字母“i”，是“二代”的意思，即“第二代”“速龙”；⑤“x4”是“四核”的意思，指这个cpu有是四核的；⑥“641”是这个cpu的型号的一部分，较完整的可识别称谓是“速龙641”；⑦“Quad-Core”这是英文的“四核”，与前面的“x4”有重复；⑧“Processor”这是英文的“中央处理器”，等价于“cpu”；⑨“2.80GHz”这是指cpu的频率为2.8G赫兹。

AMD-品牌（相对的，还有INTEL)Athlon II - AMD的子品牌，速龙系列，后面的II是指第二代的速龙UX4 - 是指这个U是4核的速龙系列641 - 指CPU的具体型号，这个U是入门的四核，性能一般，不带核显QUAD-CORE - 字面意思，四核Processor - 字面意思，处理器2.8GHz - 处理器频率，指每一个物理核心的频率，AMD的频率和INTEL的频率不能划等号，这个U的性能比较低下
AMD Athlon(TM)II X4 641 Quad-Core Processor2.80 GHz这些信息表示是如下：AMD是美国超威半导体公司的简称Athlon(TM)中文译是速龙，是AMD公司处理器一个型号的注册商标II X4 表示是速龙二代，X4表示是四核641 是型号Quad-Core Processor表示是英文四个核心的处理器2.80 GHz表示是处理器的主频。参考资料：百科，
