The size of each MMX (Multimedia Extension) register is
A. 32 bits
B. 64 bits
C. 128 bits
D. 256 bits
Answer:A
The size of each MMX (Multimedia Extension) register is
A. 32 bits B. 64 bits C. 128 bits D. 256 bits
Explanation: The MMX registers use only the 64-bit mantissa portion of the general purpose floating point registers, to store MMX operands. Thus, the MMX programmers virtually get eight new MMX registers, each of 64 bits.
