The major limitation of 80386-387 system is

(a) low speed

(b) 80386 sends data using an I/O handshake technique

(c) 80386 returns to real mode by reset operation

(d) none of the mentioned

I got this question in my homework.

This interesting question is from Numeric Coprocessor topic in division 32-bit Processors-80386, 80387 and 80486 of Microprocessor

The correct answer is (b) 80386 sends data using an I/O handshake technique

To elaborate: The major limitation of 80386-387 system is that the 80386 sends instruction or data to 80387 using an I/O handshake technique. To perform this handshaking and to carry additional house keeping tasks, 80386 requires 15 clock cycles or more.
