I have been trying to find the Absolute value of an integer which is designated to Verilog core using Xilinx C running on Microblaze, what i have seen is that Verilog treats the negative number as a positive number.
I have tried all data types :
My c code is:
signed int data,value; data=-20;value=0; putfsl(data,0); getfsl(value,0); signed int data1,value1; data=20;value=0; putfsl(data1,0); getfsl(value1,0);
After getting the values of variables I printed them on Hyperterminal.
On my Verilog side the code was:
I also tried this code but results were similar
if(in<0) out=-in; else out=in;
Kindly help me out!
I have also tried other data types and changed parameters but results have not worked out to be I always get the same number I input i.e
statement is not being true, I also tried in<=0.
