Vector Signal Imaging Processing Library 1.4 (Sourcery VSIPL++ branch)

The Vector Signal Image Processing Library is an application programming interface (API) defined by an open standard. This package is a reference implementation of this specification. License: GNU General Public License (GPL) Changes:
This release implements return-block optimization (RBO). It improves and increases the usage of high-performance math libraries. It improves and increases the usage of SIMD instructions. The API has been extended to include optimized implementations of threshold, axpy, maxval, and minval. Performance of computations involving sparse matrices and tensors has been improved. There are assorted bugfixes.

NAME

       IPC::Signal - Utility functions dealing with signals

SYNOPSIS

	   $number = sig_num $name;
	   $name   = sig_name $number;

	   sig_translate_setup;
	   $number = $Sig_num{$name};
	   $name   = $Sig_name[$number];

DESCRIPTION

       This module contains utility functions for dealing with signals.

       Nothing is exported by default.

       sig_num chopped-signal-name
	   Returns the signal number of the signal whose name (sans "SIG") is chopped-signal-name, or undef if there is no such signal.

	   This function is prototyped to take a single scalar argument.

       sig_name signal-number
	   Returns the chopped signal name (like "HUP") of signal number signal-number, or undef if there is no such signal.

	   This function is prototyped to take a single scalar argument.

       sig_translate_setup
	   If you want to use the @Sig_name and %Sig_num variables directly you must call sig_translate_setup to initialize them.  This isn't nec-
	   essary if you only use the function interfaces sig_name() and sig_num().

	   This function is prototyped to take no arguments.

       %Sig_num
	   A hash with chopped signal name keys (like "HUP") and integer signal number values.

       @Sig_name
	   An array mapping signal numbers to chopped signal names (like "HUP").
