Changing Trends in Computer Architecture : A Comprehensive Analysis of ARM and x86 Processors

International Journal of Scientific Research in Computer Science, Engineering and Information Technology, 2021

In the modern world, we use microprocessors which are either based on ARM or x86 architecture which are the most common processor architectures. ARM originally stood for ‘Acorn RISC Machines’ but over the years changed to ‘Advanced RISC Machines’. It was started as just an experiment but showed promising results and now it is omnipresent in our modern devices. Unlike x86 which is designed for high performance, ARM focuses on low power consumption with considerable performance. Because of the advancements in the ARM technology, they are becoming more powerful than their x86 counterparts. In this analysis we will collate the two architectures briefly and conclude which microprocessor will dominate the microprocessor industry. The processor which will perform better in different tests will be more suitable for the reader to use in their application. The shift in the industry towards ARM processors can change how we write softwares which in turn will affect the whole software development environment.

A Practical Application of ARM Cortex-M3 Processor Core in Embedded System Engineering

International Journal of Intelligent Systems and Applications

Embedded Systems Engineering has grown in recent years to become an integral part of our daily living as it finds striking applications in various spheres of our lives. These range from Manufacturing, Electronic Health, Telecommunications, Construction and Robotics to numerous other fields. Primarily, Embedded Systems are usually a combination of selected electrical and electronic components functioning together under the direct control of a programmed controller. They serve fundamentally as additional units incorporated within already existing infrastructures with the sole aim of providing dedicated services to the larger infrastructure. Many of the controllers used operate on uniquely designed processor cores, instruction sets, and architecture profiles. This paper seeks to elucidate the application of the ARM Cortext-M3 processor based NXP LPC 1768 Microcontroller unit in the design and development of a Temperature Monitoring and Logging System. The write-up starts off with an overview of the principal ARM processor core families, architecture profiles, instruction sets and subsequently, demonstrates its utilization in the design of a Temperature Monitoring and Logging System. The paper shows how the NXP LPC 1768 Microcontroller Unit successfully serves as the brain of the temperature logger device through its standardized interfacing with a TMP102 temperature sensor using the Inter-Integrated Circuit (I2C) protocol. The Microcontroller is programmed using Embedded C while other unique functionalities of the ARM Cortex-M3 core such as Interrupt Handling and System Tick Timer efficiency are also explored.

Design and Implementation of Training, Experiment and Development Set for Arm Based Microcontrollers

2017

In this study, a training, experiment and development set was designed by using ARM architecture 32-bit STM32F407VTG6 microcontroller for use in the electronic departments of Vocational and Technical Schools. On the experiment set, in addition to sound, light, infrared, color, temperature, humidity, ultrasonic sensors, accelerometer, gyroscope, magnetometer, pressure sensor, liquid crystal display, 7 segment indicator, LEDs, DC motor, servo motor, SD card reader and Ethernet LAN module; components belonging to Bluetooth, RS232, RF, I2C, SPI, CAN communication protocols were used. Application software for each component was developed in the C programming language so that the components can be learned by performing applications. With this study, it is aimed to learn ARM architecture microcontroller structure, to support the operating logic of environmental components by supporting with sample software, to make and develop microcontroller system tests.

ARM Architecture and RISC Applications

ARM, originally Acorn RISC Machine, later Advanced RISC Machine, is a family of Reduced Instruction Set Computing (RISC) architectures for computer processors, configured for various environments. British company ARM Holdings develops the architecture and licenses it to other companies, who design their own products that implement one of those architectures— including systems-on-chips (SoC) that incorporate memory, interfaces, radios, etc. It also designs cores that implement this instruction set and licenses these designs to a number of companies that incorporate those core designs into their own products. If you've paid any attention to smartphones and tablets you've likely heard of the term " ARM " used to refer to the hardware inside. It's thrown around left and right, often as a point of differentiation from laptops and desktops, which use Intel x86. The Key To ARM Is RISC. RISC is, in its broadest form, a design philosophy for processors. It stems from a belief that a processor with a relatively simple instruction set will be more efficient than one which is more complex. The term originally came into use back in the 1980s with a research project called Berkeley RISC that investigated the possibilities of this approach to design and then created processors based on it. All ARM processors are considered RISC designs, but this doesn't mean much because RISC itself is simply an approach to design rather than a technological standard or processor architecture. Still, a basic understanding of RISC properly frames ARM.

Study of Embedded Software and Hardware using 8051, AVR & ARM Platform

Embedded system requires a design which combines hardware and software. The key of embedded system is embedded microcontroller. Embedded computing both hardware and software occupy an important place in India’s economy by providing more than billions jobs in this sector. Embedded system is trend for engineers. Real world problem importantly in embedded system is hardware and software design and utilization. The concept underlying theory in embedded hardware i.e. microcontroller and microprocessor platform and embedded software ie. Programming in c, c++, java etc requires challenging task, integration and testing to students both graduate and post graduate. To have implementation skill and optimization close to ‘embedded microcontroller’ platform this paper address basic skill in hardware, software design and development to understand the theory and is very important in context to products development approach.
