multiplication of 1 digit BCD with 1 digit BCD

hi all!!
my assignment need us to design a circuit that can handle a multiplication of 1 digit BCD with 1 digit BCD, the answer must in BCD.

u guys have any idea?

do u guys have Binary to BCD converter circuit?

if got, email me ya~ david_lai84@hotmail.com thz...

thz a lot ya~

EPROMs are pretty cheap and easy to use. your input is the two 4 bit BCD values as the address and the value at that location is the result. just fill out the 256 entry array with the values you want. The performance is basically the cost of one EPROM access.

hope your teacher appreciates the help you are getting here.

table lookup, it's A Good Thing.

I saw ur reply...

do u mean I have to use truth table to write all the possible out then only do?

well, you should do your own work. you've gotten more than enough help, go do you homework.
