对于典型的MIPS五级流水线处理器（不前递），下面这段代码中，哪条指令会遇到数据冒险？instruction 1: add $1, $2, $3instruction 2: sw $2, 0($1)instruction 3: lw $1, 4($2)instruction 4: add $2, $2, $1
A: instruction 2
B: instruction 4
C: instruction 1
D: instruction 3
A: instruction 2
B: instruction 4
C: instruction 1
D: instruction 3
举一反三
- There is a subi instruction in MIPS instruction set.
- When an instruction is executed the address of the next instruction is put into the PC. （ ）
- 名词解释：指令（ instruction）
- 【单选题】如图示代码,下面哪个是正确的输出结果 A. 0 1 2 3 4 5 B. 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 C. 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 D. 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5
