Question

Convert the following assembly code into "symbol less" code by replacing each symbol (variable or label) with its corresponding value (number). Also, please label the ROM address (line number) for each real instruction. 1. Sum.asm Assembly Code ROM Address Assembly Code (raw with symbols) (line number) (cleaned and without symbols) // Computes sum = R2 + R3 // (R2 refers to RAM[2]) @R2 D=M @R3 D=D+M // Add R2 + R3 @sum M=D // sum = R2 + R3 2. Max.asm Assembly Code ROM Address Assembly Code (raw with symbols) (line number) (cleaned and without symbols) // Computes R2=max(R0, R1) // (R0, R1, R2 refer to // RAM[0], RAM[1],RAM[2]) @R0 D=M @R1 D=D-M @OUTPUT_FIRST D;JGT @R1 D=M @OUTPUT_D 0;JMP (OUTPUT_FIRST) @R0 D=M (OUTPUT_D) @R2 M=D (INFINITE_LOOP) @INFINITE_LOOP 0;JMP
