mediumvv.v

A code writing by Verilog which can find medium value. With a C file to see the simulation results.

module mediumvv(data1,data2,data3,mediumvalue);
    input [7:0] data1, data2, data3;
    output [7:0] mediumvalue;   
    wire [7:0] mediumvalue;
    wire [7:0] temp1,temp2,temp3,temp4,temp5,dat1,dat2,dat3;    
    
    assign dat1=(data1<127)?(data1+128):(data1-128);//if value is positive +128
    assign dat2=(data2<127)?(data2+128):(data2-128);//if value is negative -128
    assign dat3=(data3<127)?(data3+128):(data3-128);    
    
    assign temp1=(dat1>dat2)?dat1:dat2;
    assign temp2=(temp1>dat3)?temp1:dat3;//maximum value
    assign temp3=(dat1<dat2)?dat1:dat2;
    assign temp4=(temp3<dat3)?temp3:dat3;//minimum value
    
    assign temp5=((temp2>dat1) && (temp4<dat1))?dat1://select the medium value
                 ((temp2>dat2) && (temp4<dat2))?dat2:
                 ((temp2>dat3) && (temp4<dat3))?dat3:
                 (dat1==dat2)?dat1:
                 (dat1==dat3)?dat1:
                 (dat2==dat3)?dat2:dat1;
    
    assign mediumvalue=(temp5>128)?(temp5-128):(temp5+128);//if temp5>128 means it is positive value
							   //so -128 to get the original value.
