PowerPC and its Architecture

We all know that all the computers works according to their microprocessors. We come to an idea of performance of the computer based on its Processor. Each microprocessor has architecture. Examples of such architectures are Pentium IV, PowerPC etc.

Performance Optimization With Enhanced RISC – Performance Computing is abbreviated as PowerPC. As the name says, it uses the RISC architecture and was developed by the combined alliance of Apple, IBM and Motorola popularly known as “AIM”. It was developed in the year 1991. It was developed on the basis of Power (Performance Optimization With Enhanced RISC) architecture which was developed by the IBM and was the fastest processor at that time.

When we go back to the history of it, IBM first developed Reduced Instruction

Current(I) to Pressure(P) Converter- Construction and Operation

We have studied the operation and construction of Pressure to Current converter , now lets discuss about Current to Pressure converter. As the name suggests, in this instance, current signal is converted into pneumatic i.e Pressure signal. 

In some control systems, we will not need a current signal as output and we need a pneumatic signal, for example, if you want to connect the output of one system as input of hydraulic system, we cannot directly give a current signal as an input to hydraulic signal; here, we must give a pneumatic signal. In those cases we need current to pressure converter. Lets see the operation of Current to Pressure converter. 

I to P converter

We can construct a I to P converter by using Flapper-Nozzle arrangement, two springs and a Electro magnet. Flapper Nozzle arrangement is used to control

Pressure(P) to Current(I) Converter - Construction and Operation

Generally we know that in most of the control systems.  Input signal will be Pneumatic i.e pressure signal. In some systems, the output of the system will also be a pressure signal. We need a mechanical setup inorder to read a pneumatic output. So, for our comfort we convert the pressure signal to current signal which can be easily measured or noted. Then comes the question, how to convert pressure signal to current signal ?

P to I converter 

We can construct a pressure to current converter using a Flapper- Nozzle arrangement , Bellows and a Linear Variable Differential Transformer (LVDT) circuit. Input pressure is given to Flapper-Nozzle arrangement and the output
