Platforms:

==========

Version 9_0_4 is released on windows,

linux-glibc2.3, linux-glib2.2, linux-glib2.1, and Solaris 32 bits.

Bug Fixes

=========

1. Fixed bugs related to variable precision operations.

Enhancements

===========

1. Includes in the demo/demo_vp directory of the distribution the

files:

filter_real.v

filter_vp.v

filter_vp_fix.v

i) filter_real.v contains:

a) loading of input samples and of ideal output samples

b) a filtering of the input samples according to a Butterworth IIR LP

order 5 filter.

c) a comparison between the ideal output samples and the samples of

the filtered output done both via display and via the task compute

distance.

d) an example of plotting the input and filtered output using ptplot

from UC Berkeley.

e) fft applied to both the input and the filtered output, in order to

check the filtering.

Please note that three 1024 * 1024 point Fast Fourier transforms runs

in less than one minute on a 2GHz Pentium if the operands are of type

real as in the filter_real.v example.

ii) filter_vp.v and filter_vp_fix.v differ only in that the first one

has operands in variable precision floating point and the second

one has operands in variable precision fixed point representation.

Each of these descriptions use the FinMath extension to Verilog in

order to determine the optimal size of the operands by doing the

following:

a) loading of input samples and of ideal output samples

b) a filtering of the input samples according to a Butterworth IIR LP

order 5 filter.

c) a comparison between the ideal output samples and the samples of

the filtered output done via the task compute distance. While the

distance between the filtered output and the idel output is larger

than the acceptable distance the number of bits of the fractional

part of the representation of the operands is increased.
