c.timing not met
d.routing is tough
e.all of above
3.architecture design

a.the first image will have larger file size.
b.the second image will have a larger file size.
2.how would you round a 10b number,x,at the 3rd(上角)bit?
a.(x>>2)<<2.
b.(x>>3)<<3.
c.((x+4)>>2)<<2
d.((x+4)>>2)<<3
e.((x+8)>>2)<<3
f.((x+8)>>3)<<3
3.what happens if the number in 2 is negative?
A ignore
b.make it absolute ,do the operation in 2,and add sign back
c.none of the above
4.how would you multiply a 4 in hardware?
a.use 4 adders each is offset from the provious adder by 1bit.
