README.DFT		Example ADSP-21062 DFT Program

This directory contains an example Discrete Fourier Transform for use with 
the ADSP-21062 Development Software. A detailed discussion of these
operations can be found in the "Development Software Tutorial" chapter of
the "ADSP-21000 Family Assembler Tools & Simulator Manual".  

Files contained in this directory:
DFT.ASM		ADSP-21062 source for an example 64 point DFT
DFT.LDF		Linker description file (system description) for DFT example
DFT.DPJ		The VDSP project file for the DFT example.  The DFT project is
  		configured to produce a DXE file named DFT.dxe and an EPROM
		loader file named DFT.ldr.  
TEST64.DAT	Input data (all real) for DFT example
SIN64.DAT	Sine (and shifted Cosine) table for DFT example
MAKEWAVE.EXE	Waveform generation utility (created TEST64 and SIN64)
MAKEWAVE.C	C source for waveform generation utility

The utility MAKEWAVE can be used to create an ascii floating point file
containing the sum of sines, cosines, pulses, and random data of arbitrary
amplitudes and frequencies. It was used to create both the test input
TEST64.DAT and the sine table SINE64.DAT for the DFT example.
