Honored ContributorHow to create sine and cos waves of different frequencies using Cyclone III(VHDL)
Hi, Is there anyone can help me to deal with one problem: How to create sine or cos waves in Cyclone III FPGA in VHDL. I have no clear idea to program the VHDL code although I have search some ...

Honored ContributorCORDIC is suitable for generating the sin/cos of an angle.
You can generate sin(a + delta) from sin(a - delta) and sin(a) with a single multiply (and a shift). The only slight problen is that the amplitude can drift.
