To use the ALTERA_CORDIC IP Core, you need to follow these steps:
1. Configure the IP core parameters:
- Specify the input data widths, including the number of fractional bits and sign attribute.
- Specify the output data widths, including the number of fractional bits and sign attribute.
- Enable or disable the generate enable port.
- Enable or disable LUT size optimization (to reduce implementation cost) and manually specify the LUT size.
2. Connect the common signals:
- Connect the clk (clock) signal.
- Connect the en (enable) signal if the generate enable port is enabled.
- Connect the areset (reset) signal.
3. For each specific function (SinCos, Atan2, Vector Translate, Vector Rotate), follow the instructions in the manual to connect the input and output signals based on the desired configuration and range.
4. Implement the IP core in your design using VHDL or Verilog HDL code generation.
By following these steps and referring to the ALTERA_CORDIC IP Core User Guide, you can successfully implement fixed-point functions with the CORDIC algorithm using the ALTERA_CORDIC IP Core.
