Assembler instructions have a specific format that defines the operation and its arguments. The instruction format can vary depending on the processor architecture. Instruction encoding involves representing operations in binary form. Instructions can vary in length, from one to several bytes. Encoding instructions is crucial for the processor's efficient execution of a program.
Instructions encoding for AVR microcontrollers involve converting assembler instructions into the appropriate machine code that the processor can directly execute. Each assembler instruction is represented by a specific set of bits that define the operation and its operands.
