We know that, the program is an implementation of certain logic by executing group of instructions. To implement program logic we need to take help of some common Programming Techniques in Microprocessor 8085 such as looping, counting, indexing and code conversion. The entire group of instructions that a microprocessor is called the instruction set of that microprocessor. The instruction set determines what functions the microprocessor can perform. The 8085 instructions are classified into five functional categories. Data transfer operations. Arithmetic operations. Logical operations. Branching operations. Instruction Set of 8085. The instruction set, also called ISA (instruction set architecture), is part of a computer that pertains to programming, which is basically machine language. The instruction set provides commands to the processor, to tell it what it needs to do. The instruction set consists of addressing modes, instructions, native data 851K subscribers, Assembly Language Programming in 8085 Microprocessor (Example 2) Video Lecture From Instruction Set and Programming Chapter of Computer Science Class 12 Subject For All Students.

These instructions are written using mnemonic opcodes and labels as described previously. Assembly language source programs must be in a machine-readable form when passed to the assembler. The Intellec development system includes a text editor that will help you maintain source programs as paper tape II.
