find the max value between a given inputs

Question

hi all i need a vhdl code to find the max value from integer input where i have a four input ?? thanks a lot

what code have you done so far?

altera_forum · Answer

first start off with behavioral coding which is mostly like c using &gt; symbol... once u done with that move on to dataflow

altera_forum · Answer

i have a 4 inputs every input has only one value such as

a => 100

b => 200

c => 300

d => 400

i want to find max value between a,b,c,d should be d <= 400

how i can make it in vhdl code??

how about compare between 2 inputs first and then the other 2 inputs and the results will e compare

is it a logic idea can e executed

Draw out the logic circuit, and then write the VHDL.

you are on right track...

now design a circuit which compares two inputs and gives out the largest one

there were many ways to design this. One way can be design comparator and Mux circuits and choose the selection pin of mux based on logic
