Computer Architecture Assignment Help
Computer architecture refers to the structure and behavior of a computer as seen by the user. It encompasses information, formats, sets of instruction, and techniques for addressing memory. Also, the architectural design of a computer deals with the specification of the various functional modules like processors and memories.
Our online computer architecture experts say the following parts can be found in a general-purpose computer:
- Processor- It is considered the brain of the computer. It performs arithmetic calculations, responds to incoming information, and also generates output.
- The Primary storage – It remembers the information that is going to be used by the processor. The primary storage is connected to the processor via a system bus (wiring).
- System and expansion busses – These are wires plus connectors which are also known as the transfer mechanisms. They connect the processor to primary storage and input/output devices.
Several input and output devices usually come with a computer. We have a mouse and a keyboard for input and a printer, monitor, or speakers for output. An internal disk drive, CD reader/writer, memory key, can act as both input and output devices.
The primary storage is normally more closely connected to the processor than I/O devices are for speed reasons. Devices such as printers and internal disks are considered primitive computers. This is because they contain simple processors that transfer information to and from the processor to and from the device.

Binary and Information Coding
Input devices send words and movements to the processor as information. However, machines speak binary or electrical knowledge. For this reason, all information sent to the processor must be converted into 0’s and 1’s or electrical off or on pulses. These travel to the bus and arrive at the processor which then saves them in the primary storage.
If you are pursuing any computer-related course, you probably learned how numbers and symbols are represented in binary. Here is a review of the concept on which computer information is based:

The Central Processing Unit (CPU)
The central processing unit is the computer. It controls everything that happens in the system including computing arithmetic and related operations of numbers:
Our computer architecture project helpers have outlined below how the processor operates:
- The clock – also known as the pulse generator. It helps the control unit perform instructions in proper time steps
- The arithmetic logic unit – it performs arithmetic on the numbers held in the data registers.
- The control – It has a wiring that triggers arithmetic operations in the ALU. But how does the control unit know how to request an addition or subtraction? Well, it obtains instruction from the primary storage.
- The Instruction counter – It tells the control unit where it will find the instructions that it needs to do.
- The instruction register – This is the register where instructions can be held or copied by the control unit.
- The data buffer and the address buffer – These two registers are the drop-off point when the processor copies information from a register to primary storage.
The processor speed is usually measured in a kind of vibration speed called Hertz, which is the speed of the computer’s internal clock. A faster processor has a larger hertz number.

The primary storage (RAM)
The Random Access memory is a long sequence of full words which are also called cells. It is where numbers are stored for later use by the processor. Note that a full word is 32 bits.
From the picture, you can see that each cell is numbered by a unique address. This allows information transferred from the processor to be stored at specific addresses. The same information can later be retrieved by referring to that address.
The memory controller is itself a primitive processor. It can quickly find and address and copy the information stored in it to and from the system bus. If the processor did the work of reaching into storage to extract information, then this process will be much faster.
Terms used in RAM:
- Written – This is used to refer to when a number is copied from the processor into storage.
- Read – This refers to when a number is copied from storage into the processor.
The address lines in the diagram transfer the bits that form the address of the cell in storage that must be read or written. The data lines transfer the information between the processor’s data buffer and the cell in storage. The control lines transmit information about whether the operation is read or written to the primary storage. For a detailed document on RAM, buy computer architecture assignment from us.
Secondary storage disks
The primary storage is limited. Secondary storage like an internal disk that is found in almost all computers can be used to store programs and information that are saved for later use. The main difference between primary and secondary storage is that secondary storage is cheaper to buy. However, secondary memory is slower to read and write information to and from it.
A wide variety of programs that can be copied into primary storage for execution along with data files are stored in secondary storage. The processor executes READ or WRITE to activate secondary storage devices. Unlike LOAD and STORE, these instructions are not simple to do because secondary storage devices are slow. The processor cannot sit idle and wait for the device to complete its work. It has to make a request for a read or write and then proceed to other work.
Here is an instruction cycle on how a processor might execute a WRITE instruction to the disk:
- Fetch -Instruction from primary storage is obtained by the control unit and placed in the instruction register
- Decode – The instruction is read by the control unit to determine if it is WRITE. The name of the device to be read and the address on the device where information should be written is extracted. The control unit also extracts the name of the register that holds the information to be written.
- Execute – The address and data are written by the control unit to the address buffer and data buffer of the disk. The controller informs the disk along the control lines of the system bus when these WRITES are finished. It signals the disk that there is information waiting for it in the primary storage.

Types of computer architecture
Our computer architecture assignment help service covers the two main types of computer architecture;
- The Von Neumann Architecture
This type of architecture is the brainchild of John Von Neumann. It describes the general framework or structure that should be followed by computer hardware, programming, and data. Most computers in use today operate according to the Von Neumann architecture. However, there are other structures for computing that have been devised and implemented.
The Von Neumann architecture is composed of the following components:
- ALU (Arithmetic Logic Unit)
The ALU performs the logical and computational functions of the computer.
- RAM (Random Access Memory)
RAM is the fast or main memory of a computer.
- The Control Unit
The control unit directs other components of the computer on the actions that they should perform. For example, fetching of data or instruction from the memory to be processed by the ALU.
- Man-machine interfaces
These are also known as the input and output devices. They include the keyboard, mouse, monitor, speakers, etc.
Your desktop personal computer is an example of a computer-based on the Von Neumann architecture. Take our computer architecture homework help service for swift assistance with your project.
- The Harvard Architecture
This type of architecture has separate storage and signal pathways used for instructions and data. The name “Harvard” originated from the Harvard Mark I. Additionally, the data in relay latches 23-digits wide. Computers that follow the Harvard architecture have a CPU that can read both instruction and data from memory at the same time. This leads to a doubling of the memory bandwidth.
Some of the examples of computers based on the Harvard architecture include the Microcontroller (single-chip microcomputer) and DSP (Digital Signal Processing)-based computer systems. This time of architecture is usually used when code and data are in different memory blocks. It needs a separate memory block for instructions and data. One memory location can be used to access data while another memory location can be used to access the instruction. In the Harvard architecture, data storage is entirely contained in the central processing unit. Avail of our computer architecture assignment help if you need a flawless document on the Harvard architecture.
