Introduction of Microprocessor 8085 Programming

A microprocessor is a computer’s processor which incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, clock driven, register based, digital-integrated circuit which accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary numeral system. For the extensive use of 8085 in various applications, the microprocessor is provided with an instruction set consisting of various instructions such as MOV, ADD, SUB, JMP, etc. These instructions are written in the form of a programme which is used to perform various operations such as branching, addition, subtraction, bitwise logical, and bit shift operations. This book is designed as a first-level introduction to Microprocessor 8085, covering its architecture, programming, and interfacing aspects.
