Description
This short and simple package makes it easy to read and write wave files for signal processing in simulations.
This is usefull if you want to check your simulation results with Octave.
Features
There are no restrictions about the numbers of channels or the sampling rate, but it only supports the uncompressed 8, 16 or 32 bit little endian format for now.
CreatePackage.m is an very simple Octave script, which generate constant VHDL arrays for eg. filter coefficients or testpatterns.
For now only one dimesion is supported.
Status
- Production Status
All tested but only from a single person.
bugfix: reading wave file samples now signed 12.10.2008
- Features for the future
package wavefiles:
support float data type
script CreatePackage:
support more dimensions
support cell array for additional lines eg.
include = 'use ieee.numeric_bit.all;'
