1. it only costs ten minutes to go to the city centre by underground.

3. This is a sun city.This is a murder town.It take arong ten minutes to center city to take the subaway.Air is clean.It is agood place to live.I am study atBeijing Yang Gang middle school.The teachers and the students are very friendly.I visited many places in China.I like great Chinese Foods.I thing my life is very happy here!

4. CPU is the heart of a computer. The CPU used by a computer basically determines the performance and grade of the computer. With the development of CPU, the frequency has reached 2GHz. When we decide which CPU to buy or read articles about CPU, we often see parameters and terms such as external frequency, frequency doubling, cache, etc. Now I will give you a brief introction of these commonly used terms related to CPU<
CPU (central computing unit)
CPU is the brain of computer, and more than 90% of data information is completed by it. Its working speed directly affects the running speed of the whole computer. The CPU integrates tens of thousands of transistors, which can be divided into control unit; Cu), arithmetic logic unit (ALU); ALU, memory unit; Mu). According to the internal structure, it can be divided into: integer operation unit, floating-point operation unit, MMX unit, L1 cache unit and register
main frequency
the internal clock frequency of the CPU is the working frequency of the CPU ring the operation. Generally speaking, the higher the main frequency, the more instructions completed in a clock cycle, and the faster the CPU speed. However, e to different internal structures, not all CPUs with the same clock frequency have the same performance
external frequency
refers to the frequency of data transmission between system bus, CPU and peripheral devices, specifically refers to the bus speed between CPU and chipset<
frequency doubling
originally, there was no concept of frequency doubling. The main frequency of CPU and the speed of system bus are the same, but the speed of CPU is faster and faster, so frequency doubling technology is born. It can make the system bus work at a relatively low frequency, and the CPU speed can be infinitely improved by frequency doubling. Then the calculation method of CPU dominant frequency becomes: dominant frequency = external frequency x frequency doubling. In other words, frequency doubling refers to the multiple of the difference between CPU and system bus. When the external frequency remains unchanged, the higher the frequency doubling, the higher the main frequency of CPU
cache (Cache)
CPU processing data is mostly transferred from memory, but the operation speed of CPU is much faster than that of memory. For this purpose, a memory is placed in the transmission process to store data and instructions frequently used by CPU. This can improve the speed of data transmission. It can be divided into first level cache and second level cache
L1 cache. It is integrated in the CPU for the temporary storage of data in the process of data processing. Because the cache instructions and data work at the same frequency with the CPU, the larger the capacity of L1 level cache is, the more information is stored, which can rece the number of data exchange between CPU and memory and improve the efficiency of CPU. However, because the cache is composed of static RAM and the structure is complex, the capacity of L1 level cache can not be too large in the limited CPU chip area<
L2 cache
is L2 cache. Due to the limitation of L1 level cache capacity, in order to improve the computing speed of CPU again, a high-speed memory is placed outside the CPU, that is, L2 cache. Working frequency is flexible, can be the same as the CPU frequency, can also be different. When the CPU reads data, it first searches L1, then L2, then memory, and then external memory. So the influence of L2 on the system can not be ignored
memory bus speed: (memory bus speed)
refers to the speed of data exchange between CPU and L2 cache and memory
expansion bus speed: (expansion bus speed)
refers to the data transmission speed between CPU and expansion device. Expansion bus is the bridge between CPU and external devices
address bus width
simply speaking, it is the amount of memory the CPU can use and the physical address space where data can be read
data bus width
the data bus is responsible for the data flow of the whole system, and the data bus width determines the amount of information transferred between CPU and secondary cache, memory and I / O devices
proction process
in the process of CPU proction, various circuits and electronic components should be processed, and wires should be made to connect various components. The precision of its proction is expressed in micron (UM). The higher the precision is, the more advanced the proction technology is. More electronic components can be made in the same material, and the thinner the connecting line is, the more integrated the CPU is, and the less power consumption the CPU consumes. In this way, the main frequency of CPU can also be improved, and the maximum frequency can reach 600MHz in 0.25 micron proction process. The CPU of 0.18 micron can reach the level of GHz. CPU with 0.13 micron proction technology will be on the market soon
working voltage
refers to the voltage required for the normal operation of CPU. Increasing the working voltage can strengthen the internal signal of CPU and increase the stable performance of CPU. But it will lead to the heating problem of CPU, which will change the chemical medium of CPU and rece the service life of CPU. In the early days, the working voltage of CPU was 5V. With the improvement of manufacturing technology and main frequency, the working voltage of CPU changed greatly. The voltage of PIII CPU was 1.7V, which solved the problem of CPU overheating<
MMX (multimedia extensions) is the earliest SIMD instruction set developed by Intel, which can enhance the speed of floating-point and multimedia operations<
SSE (streaming SIMD extensions) the second generation SIMD instruction set developed by Intel has 70 instructions, which can enhance the speed of floating-point and multimedia operations< br />
3DNow!( 3D no waiting) the SIMD instruction set developed by AMD company can enhance the speed of floating-point and multimedia operations, with 21 instructions.
