Hi everyone,

I have two questions

1. How to calculate Absolute Value in Verilog (e.g. b=|a|)?
2. How to access single memory location in 2-Dimensional memory? I have 16x16 memory defined as [0:16]mem[0:16] and I want to get value of 3rd column and 4th row?

Looking forward to hear from you soon, thanks in advance.

Regards,
Umar
 

1. assign x_abs = x[LEN-1] ? -x : x;
2. i'm going to assume a geometry, mem[4][3]. This would get the 3rd bit of the 4th word.
