project: "adding and subbracting 2 single digit (base 10) number"
i have created all blocks upto my knowledge so i need guidelines of practical implemetation....
i also attacted blocks of operation i created
plz see the block here:
http://picasaweb.google.com/vishnu89chand/Project#5278540500885089778discrb
explantion of block:
I/p: i prefer to place keypad for getting input
buffer: 4 bit Parallel In Parallel Out shift register (2 number with complemented clk)
(to store addend when clk is active low and augend when clk is high)
process: it is bcd adder cum subbractor
O/p : i prefer to use 7 segment disply
actual problem now i am facing:
1)i dont know how to use keypad i need circuit of that and how to use it
2)is there any other way of storing addend and augend (is it necessary)
3)how to use 7 segment display
any suggestion of my circuit how to futher simplify it and make it more Relaiable
any other idea for this process
