2.2 Definition of a Microcontroller Microcontroller‚ as the name suggests‚ are small controllers. They are like single chip computersthat are often embedded into other systems to function as processing/controlling unit. For example‚ the remote control you are using probably has microcontrollers inside that do decodingand other controlling functions. They are also used in automobiles‚ washing machines‚microwave ovens‚ toys ... etc‚ where automation is needed.The key features of microcontrollers include:

COMPUTER ARCHITECTURE AND DESIGN’S REVIEW QUESTIONS From “Computer Organization and Architecture” book‚ by W. Stallings - 8th edition - Pearson PAGE 15 - CHAPTER 1 / INTRODUCTION Review Questions 1.1. What‚ in general terms‚ is the distinction between computer organization and computer architecture? Computer organization is how devices is implemented. Computer architecture is those atributes visible to the programer. Computer architecture refers to those attributes of a system visible

Computers) were developed through the innovation of Intel’s microprocessors. In the early 70’s increased competition from Japanese semiconductor manufacturers had dramatically reduced the profitability of this market this made Intel to shift the company’s focus to microprocessors. From the late 80s until the late 90s Intel had a 10-year period of unprecedented growth as the primary hardware supplier to the PC industry‚ supplying microprocessor to IBM. Intel’s product line of Pentium processors had

competition became fierce and the PC market began to take hold. Intel executives later made a dramatic decision to exit the DRAM business and focus resources on the Intel invented microprocessors. In January 1997‚ Intel was ranked among the top five American companies. For the most part‚ Intel’s success had been due to its microprocessors. Notwithstanding the company’s remarkable history and success‚ company executives worried about the challenges ahead. Almost thirty years later‚ the questions are‚ "How can

(VLIW) Computer Architecture ABSTRACT VLIW architectures are distinct from traditional RISC and CISC architectures implemented in current mass-market microprocessors. It is important to distinguish instruction-set architecture—the processor programming model—from implementation—the physical chip and its characteristics. VLIW microprocessors and superscalar implementations of traditional instruction sets share some characteristics—multiple execution units and the ability to execute multiple operations
