Sine Wave Table

SINE WAVE TABLE

This sine wave table is normally used by FFT routines that use bit-reversed address

pointers. This table can be used as it is for up to 512 point FFTs; however, for larger FFTs,

the table must be copied to a different memory location to allow the Reverse-carry

addressing mode to be used (see REVERSE-CARRY MODIFIER (Mn = $0000) in the

DSP56001 User’s Manual for additional information).
