Help with a simple problem!

[Vick]

I have this 8-bit bus, and on posedge Clock, I need to read it 4
consecutive clock cycles to store them in a 32-bit register.

I tried using a 8-bit shift register but it doesnt work.

thanx,

For this type of homework question, your name should be
"iamnobodiesengineer" and thanx for asking.

BTW why is is so cool for newbies to deliberately mispell so many
words these days?

Why don't you try a byte-shift register?

Why not have rotating byte-enables that sequence through the 32 bits in
a circular fashion?

Why not have a 2 bit address that increments from 0 to 3 so that a different
bank of FF are selected for each clock?

As the other dude said ... if you can't solve problems as easy as this you
are gonna fail the mid-term.
