Abstract
	this article defines the values of power bus resistance and inductance. These values are calculated using the example of two processors. The values of the voltage drop on the switching boards of the housing are estimated and the values of inductance are determined. This article aims to create a single output matrix for two functionally different domestic microprocessors. Placement of two functionally different crystals on the same matrix of terminals of the switching Board of the case will allow you to have two interchangeable microprocessors installed on one seat. This implementation will allow you to minimize the cost of developing computing modules, testing stands and disassembly, as well as to get the ability to use a single socket for two different processors. To create two processors with the same matrix of findings is necessary to design a breakout Board for two of the case. This article analyzes the power supply system of microprocessor cores. To analyze the power supply system of the cores, the values of voltage drops are determined for this purpose, the methodology for determining it by means of dividing it into squares is used. Since the current has a different direction in different parts of the housing substrate, it is necessary to divide it into zones. The value of the voltage drop in each zone is determined. The inductance value is calculated using the transition structures of the data layers of the housing substrates. In conclusion, a task is given to develop the motherboard for resistance and inductance. Similar calculations are made for the second housing substrate, which will have more layers of earth and power. A comparative analysis of the values with each other is performed, one processor is compared with another, the obtained values are evaluated and appropriate conclusions are made on the work done.
