Nios/memaddr

Consider a memory array of depth D and width of B bits. How many address lines are needed for this memory array?

Write a function that returns the number of address bits for a memory of depth D and width B bits. D and B will be at least 1.

unsigned int addrlines(unsigned int D, unsigned int B);

Expected solution length: Around 10 lines.

addrlines(16, 8)

r2=4

.global _start
_start:
	movi r4, 16	# Depth 16
	movi r5, 8	# 8 bit wide (128 bits of capacity)
	call addrlines
1:	br 1b    # Done

addrlines:
