Furthermore, using the C divide or modulo operators results in directly translate to built-in Verilog divide and modulo operators. Unfortunately, the built-in operators are designed as single-cycle operation, causing large penalties in clock frequency. To work around this issue, we use a C implementation of the divide and modulo operations, which is indirectly compiles them as multi-cycle operations on the FPGA. |
