The purpose of the assembler is to translate this assembly language code into machine code that the computer's processor can directly execute. The assembler takes the human-readable assembly instructions and converts them into a sequence of binary instructions.
Here's a breakdown of each line:
- MOV R1, #10: This instruction moves the immediate value 10 into register R1. 'MOV' is the mnemonic for the move instruction, 'R1' is the destination register, and '#10' indicates the immediate value (a constant) to be moved.
- MOV R2, #20: This instruction moves the immediate value 20 into register R2. Similar to the previous line, 'MOV' is the instruction, 'R2' is the destination register, and '#20' is the immediate value.
- ADD R3, R1, R2: This instruction adds the contents of register R1 and register R2, and stores the result in register R3. 'ADD' is the instruction, 'R3' is the destination register, 'R1' is the first operand, and 'R2' is the second operand.
- STORE R3, [location]: This instruction stores the contents of register R3 into the memory location specified by the label 'location'. 'STORE' is the instruction, 'R3' is the source operand, and '[location]' indicates the memory address where the data should be stored. The square brackets indicate a memory address.
