The presentation slides offer an overview of the Addressing Modes and Instruction Set of the 8085 microprocessor, detailing how operands are specified in instructions. Five methods of addressing are presented: Immediate, Register, Memory Direct, Indirect, and Implicit addressing, with an explanation of the advantages and disadvantages of the first four. Furthermore, the slides examine the Instruction Set of 8085, noting that the 8-bit processor has 246 instructions represented by an 8-bit Op-Code. The instructions are classified based on length (one, two, or three bytes) and functionality, which includes Data Transfer, Arithmetic, Logical, Branching, and Stack/IO and M/C Control Instructions. Finally, the presentation provides details and examples for several functional instruction types, such as the arithmetic operations of Addition and Subtraction, as well as the logical operations of AND, OR, XOR, Rotate, and Compare.
