The unit organization structure map of cell phone jammer is clear

The unit organization structure map of cell phone jammer is clear.
: AM-AMD, AT-ATMEL Corporation, MC-Motorola, X-XICOR companies. Special letters omitted the prefix stands for the English of the plant such as Intel, integrated circuits, in general, usually will own production plant or company name, logo, print up. Each product in the middle of the same number of models are generally interchangeable. Is customary (strict) title :: 74XX 74HCXX, 54XX, 40XX, 45XX, 28FXXX, 29LVXXX. If the circuit is more stringent component requirements, it is necessary to analyze the information provided by the manufacturer to make a decision. For example, the AN5620 note is the prefix AN Panasonic bipolar integrated circuits. The main control computer of cell phone jammer is equipped with the audio card, network card (or COM serial interface) and so on.
The number "5620" before the main function of the two circuits distinguish, "56" description is a TV with IC 76 70 audio uses 30 to 39 VCR and circuits. For details, please refer to the factory IC models is named. As well as mobile phone repair the Nagami 28Intel28 and AMD29LVXXX two types of chips, for example. Commonly used input / output interface I / O interface, said I is the input interface is the shorthand of the English IN. O is the output interface is the shorthand of the English OUT. Input / output interface circuit to the CPU and the external circuit, the connection between the channels in the device and the control circuit. Point level of the external circuit, the device size, data format, speed, work, etc. are not unified. It is the main control software of cell phone jammer .
Under normal circumstances is not compatible with the CPU (that is not directly connected to the CPU), these external circuits and equipment only through the input / output interface, a bridge, in order to carry out the transfer of information between exchanges and the CPU and the external circuit co-ordination between the equipment. I / O components on the structure and working principle and the CPU is very different, they have their own separate clock independent timing control and status flags. CPU is a high-speed components and I / O components at different speeds, so the difference between them in general can reach several orders of magnitude, while the CPU and peripheral I / O components for data exchange must be introduced to the logic unit to solve between the synchronization and coordination. Of course, other languages can be loaded for cell phone jammer .cell phone jammer protects your secrecy and confidentiality
Format conversion, the overall I / O interface functions are as follows: the operation of the single-chip data transmission, select the input, the input parts. Involved in the control of the completion of the selected I / O components and the CPU and other components of data between exchange. Now the data buffer, the CPU and the external circuit I / O components on the pace of work to achieve the match. Data format conversion. Provide the status of the peripheral components and interfaces for the CPU to better control the various peripheral components, to provide effective help. Contact control communication between the host and peripheral components. The phone interface is a very broad concept, the following classification. The main functions of the main control software of cell phone jammer will be presented in the following.
