Question 1 代写计算机架构
(1)How is the instruction “sub $t9, $s4, $s7” translated to a machine instruction code?
Answer the rs, rt, and rd fields in binary number.
(2)Describe the role of the “funct” field. (0.5 pt.)
(3) Fill the blank (A), (B), (C) and (D) in the following code sequence which calculates “A[128]=i+A[i]” (The array “A” consists of 4- byte integer elements. Assume that “i” and the base address of “A” are allocated to $s1 and $s2, respectively). (1 pt. for all)
Question 2 代写计算机架构
- Describe the roles of the following components ② to ⑤ (2 pt for all)
– Ex.) ①：Holding the address of the instruction to be executed now
⑥：Selecting data to be written to a destination register between the data read from memory and the result of ALU calculation.
Question 3 代写计算机架构
According to the truth table below, draw combination circuits for “ALU control input[1]” with MIL logic symbols (AND, OR, NOT) (You don’t have to try logic simplification.). (1 pt.)
Caution
- A copy from others can’t be accepted.
- A duplicate answer gets zero point even if it is the original answer.
