Final answer:
Limitations of ARM architecture include challenges with complex tasks due to its RISC design, a less comprehensive software ecosystem compared to x86 architectures, and potential fragmentation from the customization of ARM cores by various manufacturers.
Step-by-step explanation:
The limitations of ARM architecture revolve primarily around its reduced instruction set computing (RISC) design, which can lead to challenges in some scenarios. ARM processors are designed for efficiency and low power consumption, making them ideal for mobile and embedded systems. However, RISC processors sometimes require more instructions to carry out complex tasks compared to their complex instruction set computing (CISC) counterparts used in some desktop and server processors. This can make ARM processors less suitable for high-performance computing tasks that require substantial data processing capabilities.
Another limitation is the software ecosystem. Although the ARM architecture is widely supported in mobile operating systems like Android and iOS, there are some software and applications, particularly in the desktop and server space, that are not as readily available or optimized for ARM as they are for x86 architectures. This can restrict the usability of ARM-based systems in certain professional and high-performance environments.
