It is the portable type Cell Phone Signal Amplifier .
On the other hand, the instruction set, the greater the number of instructions is more the function of the chip, and run the program faster. Cortex cores, all ARM series CPU chip, the most powerful and fastest class. ARM9 family CPU speed is 200-400MHz, ARM11 series of 400-800MHz ARM Cortex A8/A9 up to 800-1000 + MHz [7,8,9]. ARM Cortex A8/A9 function, speed and more power, which is based on the ARM Cortex A8/A9 phone CPU chip as the core to be respected. Here will introduce the working principle and operation guide of the GPS cell phone booster in details with technical parameter, performance and maintenance described as follows.
Of course, if the second generation of Intel's Atom CPU, Moorestown, have successfully reduced the power consumption, then it may impact the dominance of the ARM Cortex A8/A9. In addition to the ARM Cortex-A8 core, the OMAP3430 chip also contains other proprietary processor cores.
Such as Figue 9.5 shows the Moto Droid and iPhone 3GS the phones motherboard logic structure. Understand the motherboard logical structure, look at the board in kind, would not be dazzled. Figure 9.6 shows the Moto Droid and iPhone 3GS the phones motherboard kind photos. Figure 9.5 and Figure 9.6 according to the look, help to understand. Should be noted that the physical map can not see the CPU chip on the motherboard, CPU and RAM is stacked. This practice is called Package on Package (PoP), and its benefits to save board space [17]. In summary, this chapter briefly describes the hardware structure of the smart phone. Hardware architecture, CPU chip is the core, other peripherals, including LCD, camera, speaker, microphone, etc., around the core of the CPU chip layout connection. This kind of cell phone booster is well received in the current market.
Within the CPU chip, the kernel is the key. The ARM series is the current mainstream mobile CPU core. In recent years, very popular ARM Cortex A8/A9. The next chapter, we will discuss the implementation of the baseband processor (BP) in the smart phone. Compare the various different approaches, what is the difference between the respective advantages and disadvantages, as well as the AP and BP both in a collaborative manner. 10] on the cottage phone with Android [10] SmartPhone communication mechanism (BP), the communication mechanism (BP) Tags: smart phone mobile phone firms Android 2010-06-03 10:31 [10] SmartPhone communication mechanism (BP), the last chapter We said, Smartphones == PC + mobile network card, this formulation is sketchy, the more precise formulation, the hardware structure of the smart phone into the application processor AP, and BP two parts, the baseband processor. The working frequency of the GPS cell phone booster is 1500~1600Mhz.
