What is the length of the interlocks after mult,multu,div,divu
on the R2000/R3000? 

Kane's _MIPS_RISC_Architecure_ says 10 and 11 cycles 
(pages C-10,C-11) for multu. Are both correct?

The examples are:
Page C-10:
	multu	a0, a3
		# 10 cycles
	mflo	t0

Page C-11:
	multu	t4, t6
		# 11 cycles
	mflo	t0
	mfhi	t1

Thanks.
