Read the text . Be ready to answer the following questions1. What is microprocessor? 2. What is the function of chip? 3. How does microprocessor operate? 4. What are the advantages of new updated versions of chips? 5. What is the storage capacity of updated chips? 6. What is the architecture of microprocessor?
A microprocessor is a scaled-down computer that fits on a single chip. Typical chip sizes measure approximately 0.5 cm. In this small space the chip may contain over a million components. Several companies are now manufacturing these chips in a variety of different designs. The performance of these chips makes them compatible with the most demanding applications in business and industry.
A microprocessor is essentially a digital device that is designed to receive data in the form of 1s and 0s. It may then store these data for further processing or perform arithmetic and logic operations in accordance with stored instructions. The results will then be delivered to an output device. The microprocessor was primarily designed for use in low-level personal computers and is largely responsible for the term microcomputer. A microcomputer has several chips, including the microprocessor, mounted on its main circuit board. This board permits the computer to perform its arithmetic, logic control, and memory functions. New developments in microprocessor technology have changed the internal construction of this device. In 1975 the first personal computers using a microprocessor began to appear on the market. Upgraded versions of these chips were soon introduced. Chips like Zilog’s Z80, MOS Technology’s 6502, Intel’s 8080, and Motorola’s 6809 all had built-in eight-line data paths or data buses. This type of chip is designed to retrieve from storage, manipulate and process a single eight-bit byte of data at a time. A sixteen-line address bus is built into these chips for memory locations and instructions. This makes it possible for the chip to have 64,000 or 64K of memory.
