Hello my friends
I want to design a floating-point adder/subtracter circuit:
I know the Algorithm (e.g: Computer Architecture,M.Mano,3rd Ed,Pritice-Hall page:359) but I have problem with the hardware implementation of the algorithm :
which IC :?: (74Series is better) and how?
it's Algorithm has too Decision blocks and a bit too hard for me to design a circuit .............. I'm beginner {I googled before without suitable result}
Is this a student educational project? Are you required to use old 74xx parts? That's a lot of wiring, and the logic won't run very fast.
Instead, how about designing the logic in Verilog or VHDL, and then implement it in an FPGA? You can buy a nice little FPGA development kit for about $100 to $150 US.
Thank You echo47
yes I'm a student but I am already do this for my Computer arch. Lab at first i must implement it with some simple IC's like shift reg. and 4bit full adder (TTL or CMOS :74 or 45)
This is the picture of floating-point addition/subtraction algorithm I want to implement this with some Register and F.A ,.... (not with programming a Micro or FPGA) any suggestion?
Added after 5 hours 55 minutes:
OK friends I did something now for a real hardware Implementation or design it in schematic software I want to know about these ICs if possible:
1/4bit comparator (compare AR & BR 4bit registers)
2/Shift-Reg. with INC,Reset,shr,shl,EN(enable)
3/Flip-Flop with En pin
4/Adder & Subtracter (I have found 7483 what about better one?)
