sine wave generation

Hi guys

I'm working on an audio synthesizer.

I used a "case" using exel (for calculate function).

you can use matlab too.

vhdl code exemple:

case nTHETA is --Table (wave)

WHEN 1 => SINE_TMP := 32799 ;

WHEN 2 => SINE_TMP := 32832 ;

WHEN 3 => SINE_TMP := 32865 ;

WHEN 4 => SINE_TMP := 32898 ;

...

WHEN 6280 => SINE_TMP := 32662 ;

WHEN 6281 => SINE_TMP := 32695 ;

WHEN 6282 => SINE_TMP := 32728 ;

WHEN 6283 => SINE_TMP := 32760 ;

WHEN others => SINE_TMP := 0 ;

end case;
