Trade

By Mike Van Dike

Trade compromising in all ages has been a lucrative business. Advances in modern technology increasingly permeate our lives and it already seems that the eavesdropping and spying every step. Video cameras watch us on streets and subways, stores and offices are under the clock surveillance. In Moscow alone, the number of firms that offer private detective services, is already more than 30. They are in the service about 2 thousand professional hunters strangers secrets. They are true professionals! Spying has become for them a very profitable business. A related site: Professor Rita McGrath mentions similar findings. The struggle for power, industrial espionage, the battle between rival factions, tidbits of life celebrities …

When it comes to really big money, the penetration of personal privacy and business secrets provided! Every housewife knows that the phone is better not to trust the maintenance of a private conversation. Learn more at this site: Professor Rita McGrath. And what can we say about the strong this world? Well armed and trained army of professionals is constantly improving the system of surveillance and how to penetrate the private lives of people. A huge variety of interesting projects every year released for sale. Conventional wiretaps ("bugs microphones) had a great spread – can now listen to as you wish: through any wall, ceiling and roof. The signal is transmitted over distances of beetles, measured in hundreds of meters and the battery life of modern beetles can be up to several months. Often the bugs are installed on telephone lines. There are methods that do not require a "bite" in wire – simply place the "bug" with him.

CISC Architecture

By Mike Van Dike

The main disadvantage of processors based on the CISC architecture is the large number of possible ways to send data, which leads to a complication of operations using different addressing methods. All in CISC micro- processors have a different format, different number of operands, as well as different time for various instructions. Analysis of instruction set processors based on the CISC architecture, showed that most used in the programs (80%) CPU instructions are only 20% of all teams CISC processor, while 80% of teams underutilized. To solve the problems inherent in CISC architecture, we developed a new RISC architecture. Core calculator, made by RISC architecture contains a set of commonly used micro-due to what the calculator on a chip was made possible deployment of more general-purpose registers. The main advantages of RISC architecture is the presence of the following features: A large number of general-purpose registers.

Universal format for all instructions. Equal time execution of all instructions. Almost all of shipping operations Data carried on the route register – register. These features enable you to handle the flow of command instructions to a conveyor principle, ie synchronize hardware parts, taking into account serial transfer control from one hardware unit to another. Hardware blocks, allocated in the RISC architecture: Block loading of instructions includes the following components: instruction fetch block from memory instructions, instruction register, and places the instruction after the sampling and decoding unit instructions.

This stage is called the step sampling instructions. General purpose registers in conjunction with power management registers form the second stage of the pipeline that is responsible for reading the operands of instructions. The operands can be stored in the statement itself or in a general-purpose registers. This stage is called stage sampling operands. Arithmetic logic unit with control logic, which is based on the contents of the register instruction, determines the type carried out by the micro. The source of data in addition to instruction register can be instruction counter, when the micro-conditional or unconditional jump. This stage is called the executive stage pipeline. Set consisting of general purpose registers, logic, and sometimes write from RAM form a step of maintaining data. At this stage the result of the instructions are written in general purpose registers or in main memory.
