23 lip 2018 · The concept of a modulus in real number math is a bit weird since the result of the division of two real numbers should be a real number (ignoring zero). If however, you want something like fmod in C/C++, you can implement it like so: real x, d, r; assign r = x - d * $floor(x / d); // Implements fmod(x, d) or "x % d" for real x, d.
17 lut 2022 · I would like to have a synthesizable and optimized solution for the modulus operator in Verilog (%) for the nonpower of two integers. cnt_mod <= cnt % 3; For power of two integers (n_arg), it could be seen as a left shifting process followed by truncation to n_arg bits.
Verilog operators operate on several data types to produce an output. Not all Verilog operators are synthesible (can produce gates) Some operators are similar to those in the C language. Remember, you are making gates, not an algorithm (in most cases) Arithmetic Operators.
22 kwi 2013 · Is it possible to get both the modulus and quotient of division in a single operation in C++?
Verilog math functions can be used in place of constant expressions and supports both integer and real maths. Integer Math Functions The function $clog2 returns the ceiling of log 2 of the given argument.
21 wrz 2021 · The algorithm requires addition, subtraction and multiplication in modulo 2 32. I've been told that I can use conventional +, -, * and / operators in Verilog if I define <stdint.h> in the header and use variables of type uint32_t.
I have googled the above question, and found that someone suggests avoiding using the Modulus % if you want to make the verilog code synthesizable. Could someone specify it more? According to my understanding, the modulus could be synthesizable (e.g. m % n) if the n is an small integer and fixed.
