Processor architectures for computers, mobile devices, and servers vary in performance and functionality. A reduced instruction set computer (RISC) and complex instruction set computer (CISC) differ in frequency and instructions in clock rates. The application of choice for the CPU architecture is a mobile device, as it is experiencing the most diversification in the industry today. RISC technology was taken as a priority, as it allows to speed up the execution of single processes, increase clock frequencies, reduce heat generation, and optimize power consumption.
RISC is a multifunctional solution, the main advantage of which is the flexibility for creating applications and other pieces of software. It has been noted that this technology allows the CPU architecture to adapt to chips from other vendors such as Samsung and Snapdragon (Gayde, 2020). Therefore, ARM, the flagship supplier of RISC processors, and other companies can create new ways to use simple decoding to improve mobile devices’ efficiency. On the other hand, this solution covers user preferences, such as energy efficiency and temperature reduction. It is apparent that a smartphone is a multitasking device today, but it can provoke rapid discharge and challenges with heating the back panel. Consequently, creating multiple singular tasks instead of one complex one is more efficient for a mobile device to increase power and improve user experience (Captain, 2018). Thus, RISC is a more promising CPU architecture due to the variability of technology adaptation for various software.
The mobile device is becoming more and more diversified due to the multitude of hardware and software vendors and the user’s growing needs. RISC was chosen as the most suitable architecture for a smartphone, as it is more energy-efficient and feature-rich than CISC. Besides, this solution allows one to adapt the technology to a specific target customer’s demands using various external registers and the ability to optimize the organization of codes. Thus, RISC is more beneficial for smartphone manufacturers in the long-term perspective.
