Question

Translate the assembly program into Hexadecimal machine code. Then represent the binary representation corresponding R, I, or J format according to the respective field partitions:

a. (20000010) NOR ( $t2, $s2, $s3 ) SW ( $t2, 4($s0))
b. (00100010) NOR (01011, 01010, 01100) (101011, 01010, 0000000000000100)
c. (101011, 01010, 0000000000000100) (20000010) NOR ( $t2, $s2, $s3)
d. (20000010) NOR ( $t2, $s2, $s3 ) (00100010) NOR (01011, 01010, 01100)

Answer 1

To convert the assembly program into hexadecimal machine code, we need to understand the R, I, and J formats. R-type format is used for the NOR instruction and involves three registers, while I-type format is used for the SW instruction and involves a register and an immediate value.

Step-by-step explanation:

To convert the given assembly program into hexadecimal machine code, we need to understand the format of the instructions. The R-type format is used for the instruction NOR, which involves three registers. The I-type format is used for the instruction SW, which involves a register and an immediate value. The J-type format is not used in the given code.

Let's convert the given instructions into hexadecimal machine code:

1. NOR ($t2, $s2, $s3): The opcode for NOR is 000000. $t2, $s2, and $s3 are registers, represented by their binary equivalents: $t2 (01010), $s2 (10010), and $s3 (10011). The function code for NOR is 100111, so the hexadecimal machine code is 000000 01010 10010 10011 100111.
2. SW ($t2, 4($s0)): The opcode for SW is 101011. $t2 is a register, represented by its binary equivalent: $t2 (01010). 4 is the immediate value, represented by its binary equivalent: 0000000000000100. $s0 is a register, represented by its binary equivalent: $s0 (10000). So, the hexadecimal machine code is 101011 01010 10000 0000000000000100.
