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.
The project was reduced arrears tenants. Shopping center "Mirror" is located in the town of Bor – Bor district administrative center of Nizhny Novgorod region. Average attendance at the shopping center "The Mirror" – 6000 – 7,000 people per day. Management Company Trade Center used for accounting and tax accounting software "1C: Enterprise 8", but needed a dedicated system for automatic calculation rent with the area and trade. Bizzi & Partners can provide more clarity in the matter. To meet the challenges of leadership turned to the experts "1C: Accounting and Trade" (ICE), which developed the software, "BIT: Accounting for leases 8." With the help of the program were automated accounting following areas: Accounting and facilities of the leased premises: an inventory of the premises, the registration of communal resources, adjustment of the floor area, accounting in the same room space different categories with different rates of rent; analysis of employment land; Work with the treaties: the management of leases and utility payments of compensation, taking into account changes in the terms of contracts, accounting for the mutual contracts in conventional units with the possibility of the exchange rate band; Settlements: rental rates, rental value of tenant turnover, utility services, compensation payments; Accounting for interim payments on leases.
The introduction of simplified control debt tenants, thereby reducing the total debt. The company managed to keep a record of contracts in accordance with industry-specific enterprise. Company "1C: Accounting and Trade" (ICE), the official partner of the firm "1C" in 1997, is now the largest network of franchise companies "1C". The company has 50 BIT offices, which operate in three countries: Russia, Ukraine and Kazakhstan. Specificity of the ICE is not only the automation of the enterprises on the basis of "1C: Enterprise", but also training, counseling clients on the full range professional issues. During the work the company produced over 80,000 successful installations of automated systems. In the state of more than 2,000 employees, most of which was certified by "1C". Quality Management System Company "1C: Accounting and Trade" (ICE) in five offices in Moscow, including in the Central, in three offices in St. Petersburg, including the Central, and offices in Krasnoyarsk, Kiev, Samara, Kazan , Saratov, Rostov-on-Don, Ekaterinburg, Irkutsk, Chelyabinsk, certified for compliance with international quality standard ISO 9001:2000.
