What is NPU? How is it different from CPU and GPU?
With the increasing demand for fast and efficient data processing, microprocessors like NPU have become more popular than ever. In this article, let's learn about NPU, how it works and the benefits it brings with TipsMake .
What is NPU?
NPU, or Neural Processing Unit, is a specialized microprocessor designed to process deep learning and artificial intelligence (AI) algorithms. The main purpose of NPU is to optimize the processing of complex tasks related to machine learning, helping AI applications work faster and more efficiently.
NPU was developed to overcome the limitations of CPU (Central Processing Unit) and GPU (Graphics Processing Unit) in the field of information processing. While CPU is often used for diverse computing tasks and has the ability to process sequentially, GPU is powerful in parallel processing but cannot be optimized for deep learning tasks like NPU.
How does NPU work?
NPUs work on deep learning algorithms, where computations are performed through millions of simple mathematical operations.
Parallel processing
One of the biggest strengths of NPUs is their ability to perform parallel processing. This means they can process millions of operations at once, making them ideal for AI applications that need to process large amounts of data. This not only improves processing speed, but also allows NPUs to handle complex models that would be difficult for a CPU or GPU to handle.
Optimizing deep learning algorithms
NPUs are optimized for deep learning algorithms, which means they are designed to best perform the calculations required to train and evaluate AI models. Compared to CPUs and GPUs, NPUs offer higher performance for these tasks thanks to their unique hardware architecture.
Use memory efficiently
The NPU is also designed to use memory more efficiently. Instead of having to access slow RAM, the NPU can store data closer to the processing cores. This reduces processing latency and improves overall performance.
Important Features of NPU
- Supports advanced AI computations: Including operations such as regression, classification, and clustering. This enables NPUs to handle more complex models and deliver more accurate results than other types of processors.
- Energy saving: As technology advances, the need for energy saving becomes more important than ever. NPUs are designed with energy saving in mind, helping to reduce operating costs for AI applications.
- Scalability: NPUs also allow for greater scalability than CPUs and GPUs. This means that developers can easily upgrade their systems without having to change the entire architecture. NPUs can be integrated into existing systems or used independently depending on the user's needs.
Important Features of NPU
What benefits does NPU bring?
The adoption of NPUs in today's technology applications not only brings performance improvements, but also opens up many other benefits.
- Increased processing speed: With parallel computing capabilities and optimized deep learning algorithms, NPUs can perform complex calculations much faster than CPUs and GPUs.
- Reduced operating costs: Using NPUs helps reduce hardware and power costs, especially in large data centers. Deploying NPUs also helps optimize production and application development processes, thereby reducing the time and resources required to complete technology projects.
- Improved accuracy: NPUs can improve the accuracy of AI models over time. This is especially important in areas like healthcare, finance, and self-driving cars, where errors can have serious consequences.

When to use NPU?
The decision to use an NPU instead of a CPU or GPU depends on the specific needs and goals of each application. Here are some scenarios where an NPU might be considered the best choice.
- AI and deep learning applications:
If you are developing an application that requires complex AI algorithms, such as object recognition, semantic analysis, or speech processing, then NPUs are the optimal choice. NPUs are capable of increasing processing speed and improving accuracy, which is important in applications that require high reliability.
- Mobile devices and IoT:
Using NPUs in mobile and IoT devices will help save energy and increase performance. Devices such as smartphones or security cameras can benefit from integrating NPUs, allowing AI tasks to be performed locally without the need for an internet connection.
- Research and development projects:
If you are a researcher or software developer looking for an efficient solution to test deep learning models, NPU is a great choice. NPU saves time and resources during development, allowing you to focus on improving your algorithms and models.
Conclude
NPU is a major step forward in the field of information processing, especially in artificial intelligence applications. With fast processing, energy saving and high accuracy, NPU is becoming the first choice for developers and businesses.
Compared to CPUs and GPUs, NPUs are not only superior in performance but also open up many new opportunities for future technology. Understanding NPUs, how they work and their benefits will help you make the right decisions in applying the technology in your projects.
