introduction to microprocessors

SUMMARY The various concepts and terms discussed in this chapter are summarized below: Computer Structure · Digital Computer-a programmable machine that processes binary data. It includes four components: CPU (ALU plus control unit), memory, input, and output. · CPU-the Central Processing Unit. The group of circuits that processes data and provides control signals and timing. […]

MICROPROCESSOR INSTRUCTION SET AND COMPUTER LANGUAGES Microprocessors recognize and operate in binary numbers. However, each micro­processor has its own binary words, instructions, meanings, and language. The words are formed by combining a number of bits for a given machine. The word (or word length), as defined earlier, is the number of bits the microprocessor rec­ognizes […]

How Does the Microprocessor Work? Assume that a program and data are already entered in the RJW memory. (How to write and execute a program will be explained later.) The program includes binary instructions to add given data. and to display the answer at the seven­ segment LEUs. When the microprocessor is given a command […]

Organization of a Microprocessor-Based System Figure 3 shows a simplified but formal structure of a microprocessor-based sys­tem or a product. Since a microcomputer is one among many microprocessor ­based systems, it will have the same structure as shown in Figure 3. It includes four components: microprocessor. input, output; and memory (Read/Write Mem­ory and Read-Only Memory). […]

MICROPROCESSORS A microprocessor is a multipurpose, programmable logic device that reads binary instructions from a storage device called memory, accepts binary data as input and processes data according to those instructions, and provides results as output . A typical programmable machine can be represented with three components: mi­croprocessor. memory, and 110 as shown in Figure […]
