D$\mathrm{.}3)$ Byte and word addressing.

a$)$ How many bits does a processor need internally to address a $32$M x $32$ memory

if the memory is word addressable?

b$)$ How many bits does a processor need internally to address a $32$M x $32$ memory

if the memory is byte addressable?

c$)$ At what physical word address would we find the word at processor address

$0$x$0003$FC if the memory is word addressable?

d$)$ At what physical word address would we find the word at processor address

$0$x$0003$FC if the memory is byte addressable?

e$)$ If the memory is byte addressable, what is the physical word address for

the word that contains the byte at processor address $0$x$79$E$423?$

f$)$ If the memory is byte addressable, what is the processor word address for

the word that contains the byte at processor address $0$x$79$E$423.$

In the processor word address the offset i$.$e$.$ is the last two LSBs are always

zero, representing the offset $00.$ So$,$ changing the LSBs to $00$ in the binary

representation of $0$x$79$E$423$
