Suppose an MIPS instruction's machine code is as follows: 0000 0001 1001 0111 0001 1000 0010 0100two Analyze the above binary sequence and answer the following questions Hint: separate the binary value into multiple fields using Figure 2.10.3 in Section 2.10, then interpret the op field (and the funct field if necessary) to obtain the specific instruction using Figure 2.10.2 in Section 2.10. The instruction will indicate one of the three instruction types: R, I or J. According to the type you determined, interpret the remaining fields for register names, shift amount (if necessary), and immediate/offset values (if necessary). The table to match register number with its name can be found in Figure 2.8.4 in Section 2.8. - Use the following for the type, do not enter the double quote (") characters. For R-type enter "R-type". For I-type enter "l-type" (the "I" is the letter I not number one). For J-type enter "J-type". Enter the type of the instruction: R-type - Enter the intrepreted MIPS assembly instruction following the format used by the example column in Table 2.2.2 of Section 2.2. Do not add extra spaces to the start or the end of your answer. MIPS assembly instruction for the given binary value is:

(a) In MIPS machine language, the R format instructions need an additional field (the “funct” field) to specify the instruction type (“add”, “sub”, etc.). Why can’t this be done using just the 6-bit “op” field, which all MIPS instructions have, instead? (b) Give a sequence of MIPS assembly language instructions that adds the contents of $s0 and $s1, storing the result into $s0, if the contents of $s1 are greater than 6. Otherwise, the contents of $s0 should be incremented by 28. In either case, afterwards the contents of $s0 should be copied into $s2. (c) Suppose that the starting address of an array of words is stored in $s0. Give a MIPS assembly language instruction that loads the contents of the second word in the array into $s1.
