What is a bottleneck in computer architecture?
The term “bottleneck” refers to both an overloaded network and the state of a computing device in which one component is unable to keep pace with the rest of the system, thus slowing overall performance.
In which architecture does bottleneck problem occur?
von Neumann architecture
The term “von Neumann architecture” has evolved to mean any stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the von Neumann bottleneck and often limits the performance of the system.
What are the factors that influence the design of computer architecture?
Computer architectures usually trade off standards, cost, memory capacity, latency and throughput. Sometimes other considerations, such as features, size, weight, reliability, expandability and power consumption are factors as well.
What causes von Neumann bottleneck?
The von Neumann bottleneck is the idea that computer system throughput is limited due to the relative ability of processors compared to top rates of data transfer. According to this description of computer architecture, a processor is idle for a certain amount of time while memory is accessed.
What are the bottlenecks of using a computer system?
In software engineering, a bottleneck occurs when the capacity of an application or a computer system is limited by a single component, like the neck of a bottle slowing down the overall water flow. Some examples of possible engineering bottlenecks are: a processor, a communication link, disk IO, etc.
What is an example of bottleneck?
An example of a long-term bottleneck is when a machine is not efficient enough and as a result has a long queue. An example is the lack of smelter and refinery supply which cause bottlenecks upstream. Another example is in a surface-mount technology board assembly line with several pieces of equipment aligned.
How do you solve bottleneck problems?
Here are several things you should do to contain the bottleneck:
- Never leave it idle. Because of the ripple effect on the rest of the flow, the bottleneck process should always be loaded at full capacity.
- Reduce the strain on the bottleneck.
- Manage WIP limits.
- Process work in batches.
- Add more people and resources.
What is the bottleneck problem of von Neumann architecture How will you deal with it?
Approaches to overcoming the von Neumann bottleneck include: Caching — the storage of frequently used data in a special area (usually RAM), so that it is more readily accessible than if it were stored in main memory.
What long term factors must designers of new computer architecture take into consideration during design process?
In designing a computer today, the most important considerations are usually performance and cost. Secondary metrics, which may vary in importance, include fault tolerance, power, and environmental factors such as size, cooling, and noise.
What is von Neumann bottleneck problem?
The von Neumann bottleneck is a limitation on throughput caused by the standard personal computer architecture. In the von Neumann architecture, programs and data are held in memory; the processor and memory are separate and data moves between the two. In that configuration, latency is unavoidable.
