Write a short note on computer architecture

Performance is affected by a very wide range of design choices — for example, pipelining a processor usually makes latency worse, but makes throughput better. Computer architectures usually trade off standards, power versus performance, cost, memory capacity, latency latency is the amount of time that it takes for information from one node to travel to the source and throughput.

Computer architecture

History of computers[ change change source ] The Jacquard loom was one of the first programmable devices. These ropes and drums were the language of the machine- they told what the machine did and when.

Physical Implementation draws physical circuits. For example, a music box is a machine that plays the same music over and over again.

InJoseph Marie Jacquard used punched paper cards to tell his textile loom what kind of pattern to weave. March Main article: When building the computer Z1 inKonrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.

This 3 bit field can define upto seven slaves 1 to 7. Superscalar processors may reach three to five IPC by executing several instructions per clock cycle. Here 'instruction stream' we mean an algorithm that instructs the computer what to do whereas 'data stream' i.

Scientists made a lot of digital computers, and as they did, they figured out how to ask them the right sorts of questions to get the most out of them.

The different circuit components are placed in a chip floorplan or on a board and the wires connecting them are created. Latency is the time between the start of a process and its completion. There are other types of computer architecture.

This includes all hardware components in the system, including data processors aside from the CPU, such as the graphics processing unit and direct memory access. In short, computer architecture refers to how a computer system is designed and what technologies it is compatible with.

A smart assembler may convert an abstract assembly language common to a group of machines into slightly different machine language for different implementations Programmer Visible Macroarchitecture: They are used in engineering applications where precision is mandatory.

The block diagram of MIMD computer is shown. Salve-slave communication is not possible. Johnson and Frederick P.

The rate provided is 1Mbps and uses 2. The application can learn the name of the plotter that is currently installed on the system from another process or by looking it up in a configuration file. Computer organization and features also affect power consumption and processor cost.

However, this metric is somewhat misleading, as a machine with a higher clock rate may not necessarily have greater performance. A processor only understands instructions encoded in some numerical fashion, usually as binary numbers.

The term "architecture" fits, because the functions must be provided for compatible systems, even if the detailed method changes.

For example, they wanted to tell the music box to play different music every time. Computer architecture is a specification detailing how a set of software and hardware technology standards interact to form a computer system or platform.

In short, computer architecture refers to how a computer system is designed and what technologies it is compatible with.

Computer architecture

• “Computer Architecture is the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost.

Developed and Maintained by: Gursharan Singh & Maninder Kaur Browsers Supported: 8+ 4+ 10+ 4+ 4+ Resolution: × Computer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints.

A computer is a machine (mostly electronic) that is able to take information, and A few programmers write programs in the computer's own language called machine code.

Write a note on Von Neumann Architecture.

This is known as "stored program architecture" or von Neumann architecture. Computer architecture is a specification detailing how a set of software and hardware technology standards interact to form a computer system or platform.

In short, computer architecture refers to how a computer system is designed and what technologies it is compatible with.
