☆
Which statements are true about the MIPS (32-bit) assembly language?
A
The I-type instructions are composed of the OP code (6 bits), RS (5 bits), RT (5 bits), and constant field (16 bits). Therefore, an I-type instruction can take at most two registers.
B
The instruction JUMP comprises the OP code (6 bits) and the address field (26 bits). Therefore, a JUMP instruction can jump to

2^{26+2}

bytes before or after the address specified by the stack pointer (SP) register.
C
The JR (jump register) instruction causes the PC to jump to the content of a register. Therefore, JR is a J-type instruction.
D
The logic of "logical-shift-left" and "arithmetic-shift-left" operations are different. Therefore, MIPS needs to provide instructions for each of them.
E
None of the above.
