CHAPTER 2
SYSTEM DESCRIPTION
2.1. System Functions
The following functions are performed by the system circuit:
1. Signal the microprocessor when any module send data to it.
2. Convert analog inputs.
3. Process the input data.
4. Communicate with the Ethernet module to send and receive data
5. Convert to the data output
6. Send output signal to output modules.
2.2. System Block Diagram Design
Based on the design requirement and specifications, the system block diagram shown on Figure 2.1 is developed. This block diagram defines all the function to be performed by the system. A modular approach to project design was taken. The system is designed around an Arduino Mega2560 which is based on an Atmel2560 microprocessor.
In the following section, some of the basic concept of circuit that are used in the system design are explained. Figure 2.1 System Block Diagram
2.3. Microcomputer Organization
A microcomputer is a device that operates on binary information. A typical microcomputer consists of:
1) A Central Processor Unit (CPU)
2) A Memory (RAM and ROM)
3) Input/output (I/O) ports
All these units communicate to each other through a bus structured organization as shown in Figure 2.2.
1) The CPU bring the entire system together. The function implemented by the other elements is under CPU control. Also, all instructions from memory will be fetched by CPU. Therefor all the binary substances will be decoded and become executive. A typical CPU contain of the following

What do CPU’s do? The CPU is the Central Processing Unit; its aim is to be there the act as the brain of the computer. Other common name for the CPU is the processor. It is in control of the power the computer is receiving and using and the calculations that enable to the computer to be used. CPUs come in differing form factors and each has a particular way in which it will fit on to the motherboard. The most common manufactures of this part that people will know are Intel and AMD. The CPU is in charge of allowing programmes to be used. The CPU sorts the commands of a program into an order which enables it to be used.
A CPU, is what is regularly alluded to as a processor. A processor contains numerous discrete parts inside it, for example, one or more memory reserves for directions and information, guideline decoders, and different sorts of execution units for performing number juggling or legitimate operations.
CPU stands for Central Processing Unit and it’s the brain of the computer. CPU executes instructions that enable the operating system and application software to run on a system. Inside the CPU we can find three main components which are the ALU, Control Unit and memory unit. ALU stands for Arithmetic and Logic Unit and performs calculations like addition, multiplication, division and subtraction. It also compares results using “greater than”, “less than” or “equal to”. Control Unit controls the operation of the memory unit, processor and input/output units. Memory unit is where all data that the CPU may need to process is stored. The data is stored in the memory in binary form.
Answer: hardware and software is the core of the computer without it computer cannot perform its task. The PC contains various electronic components that we are able to see when we open it. By only pc by itself cannot perform their task on their own. Our PC needs something to get instructed to set it on where we need software to perform it. There are six different component of hardware to function the computer .The first one is central processing unit(CPU )it is the brain of the
In centralized computer or minicomputer frameworks the assets like memory, stockpiling of information and system data transfer capacity ought to be managed carefully.
This section gives the details and specification of the hardware on which the system is expected to work.
The CPU is housed in the motherboard is considered the heart of the computer, it controls everything. CPU stands for central processing unit; it is one of the main components of a computer. The CPU or more commonly known as the processor is electronic circuitry which follows the instructions of the hardware and software on the computer, it effectively is a very efficient calculator carrying out arithmetic, logical, control and input/output operations.

Computer architecture is a set of rules that say how software and hardware interact to create a network or platform. In other words computer architecture is the design of the network base on the needs of the user, the system if it is there or needs to be built, and the technology that needs to go into the project. System design is all how all the hardware is set up while the instruction set architecture is the program language.
The function of the processors is to run programs and send and receive signals from the connected devices to keep computer running. Processors handle all the data and runs all the programs that allow you to complete your tasks.
Processor:It is considered as heart of the computer which controls all the operations of the computer and data processing.
