operation?


How many 4x4 multipliers would you need to split a single 8x8
multiply into multiple 4x4 multipliers?

Re: question

8x8 mult will result in 16 bit reasult.
because
what is the max value of 8 bit number ? it is 255,
then 255*255 = 65025, which needs 16 bits to represent.
you will need 2 4x4 multipliers to do a 8x8 multiplication.
