Windows on ARM: 5 tips to success

General | May 9, 2024 | 4 min read

Windows on ARM refers to the version of the Windows operating system designed to run on devices powered by Advanced RISC Machine (ARM) architecture processors, instead of traditional x86 or x64 processors. This adaptation brings Windows to a variety of devices beyond traditional laptops and desktops, including tablets, and some smartphones.

An advantage of Windows on ARM is its potential for increased battery life and improved power efficiency, as ARM processors are known for their energy efficiency compared to traditional x86 counterparts. Additionally, Windows on ARM enables manufacturers to create thinner and lighter devices without compromising performance.

However, the transition to ARM architecture also poses challenges, particularly in terms of software compatibility. While Windows on ARM can run native ARM applications, it relies on an emulation to run traditional x86 applications, which might result in performance limitations or compatibility issues.

Despite these challenges, Windows on ARM represents an exciting frontier in the evolution of computing, providing the promise of greater versatility, mobility, and efficiency for a wide range of devices.

Here are 5 tips that will elevate the efficiency of windows on ARM  

Optimize software for low power modes

ARM’s inherent power efficiency is the key to its dominance. The reduced instruction set computing (RISC) architecture of ARM processors simplifies operations and uses less power. ARM processors function remarkably frugal compared to their x86 counterparts, which translates to longer battery life and lower heat production. This efficiency adds to a more sustainable computing ecosystem in addition to improving the user experience by extending the duration of device usage.

You might implement power-saving features in software to leverage the power efficiency of ARM processors fully. Also, you can utilize low-power modes effectively by reducing background processes and optimizing resource utilization. To allow the device to enter deep sleep states and conserve power efficiently, you must ensure that applications are designed to minimize CPU usage during idle periods.

Focus on system integration and miniaturization

Beyond its power efficiency, the elegance of ARM’s architecture allows for physically smaller chip designs. ARM processors take up less silicon area than x86 processors because of their more compact design. This chip size decrease creates new opportunities for creative design. Windows on ARM devices support the spirit of downsizing by providing portability without sacrificing functionality.

When you are designing hardware for Windows on ARM devices, prioritize system integration to minimize the footprint of components. Embrace miniaturization techniques such as system-on-chip design and stacked chip packaging to reduce the overall size of the device. You can collaborate closely with chip manufacturers to leverage advancements in semiconductor technology, aiming for compact and efficient designs without compromising performance or functionality.

Implement task parallelism and load balancing

Computing efficiency involves more than just processing power; it also involves wise resource management. This is where ARM’s architecture shines, especially with multicore scaling. In contrast to x86 processors, which have a monolithic design, ARM-based systems make use of numerous low-power cores to effectively divide workloads. This method achieves a harmonic balance between power and productivity by optimizing energy utilization and improving performance for simultaneous operations.

Harness the power of multicore scaling by designing software that effectively utilizes multiple CPU cores. You might also give a thought on implementing task parallelism to break down complex tasks into smaller subtasks that can be executed concurrently across different cores. Employing load balancing algorithms will help you in distributing computational workload evenly across cores, maximizing efficiency and minimizing idle time. Consider utilizing platform-specific APIs and libraries that are optimized for multicore architectures in order to streamline development and enhance performance.

Optimize network stack and power management

In the era of constant connectivity, Windows on ARM devices embrace the ethos of perpetual engagement. Full credit goes to their integration with 4G or 5G cellular networks, these devices offer seamless connectivity even in sleep mode. This always-on feature allows for background data synchronization, reducing downtime and increasing productivity, in addition to providing fast access to web resources. Windows on ARM devices redefine efficiency in the field of connectivity by maintaining a constant connection.

The network stack should be optimized for efficient utilization of cellular connectivity in always-on mode. Implement intelligent power management algorithms that balance the trade-off between maintaining connectivity and conserving battery life. You might take advantage of techniques such as packet coalescing and batched transmissions to minimize radio activity and reduce power consumption during idle periods. Leveraging platform features for background data will be of great use in synchronizing and enabling seamless connectivity while minimizing the impact on battery life.

Enable and configure hardware security features

Efficiency includes protecting sensitive data and maintaining system integrity in addition to performance and power.
A number of integrated security features, including hardware-based encryption and secure boot, are present in ARM CPUs.Through their ability to thwart possible attacks and provide strong protection against malicious actors, these techniques strengthen the basis of Windows on ARM computers. Windows on ARM devices give consumers confidence by putting hardware security first, allowing them to work and communicate without worry.

It’s ideal to activate and configure hardware security features provided by ARM processors to enhance the security posture of Windows on ARM devices. Additionally, securing boot mechanisms will help ensure the integrity of the boot process and prevent unauthorized code execution. Utilize hardware-based encryption engines for data protection and implement secure enclaves for isolating sensitive operations. Make sure to update firmware and security patches to mitigate potential vulnerabilities and keep the device secure against emerging threats.

Windows on ARM has a bright future ahead of it, as it sits at the nexus of performance and mobility. With advancements in technology, ARM-based processors become more appealing for a variety of products due to their improved performance and power efficiency. We can expect a future where ARM-powered devices smoothly integrate into our digital ecosystems, providing longer battery life, smoother performance, and more compatibility with a variety of applications. We might anticipate an expanding ecosystem of apps designed to capitalize on the advantages of ARM processors as software developers continue to optimize their products for ARM compatibility, further establishing Windows on ARM as an appealing option for both consumers and enterprises.
