Digital Logic Design PROJECT
(do this project with circuit maker design (7485 comparator))
Design 8 bit adder/subtractor (a+b, or a-b) with following:
specifications:
1. Inputs: tow operands [A,B](8-bit each),
operation(0-addition,1-subtraction),
load(1-load new data,0-perform operation).
2. Outputs: 9 - bit (8-bit will be stored in A again).
3. Modes of operations:
a. Check if B is 0, then the output will be A.
b. Check if A is 0, then the output will be B OR B' depend
on the operation.
c. Otherwise , perform the addition or subtraction.
4. Display result on two seven segment displays + 1 LED.
please if u know the answer help me and i will be thankfull.
