Run Time Licenses are not required
when the SigLib OBJECT code is embedded in executable module(s)
which form part, or all of a product(s).
SigLib is available, as standard
with full source code. As an alternative, for those that do not
wish to have access to the source code, SigLib is also available
as a binary release. The binary release includes libraries for
the following processors, Pentium Windows, Borland and Microsoft
C/C++ compilers (Includes a DLL, which can be accessed from
Visual Basic, Delphi, Excel and many other programs. This library
is pre-compiled and while every effort has been made to ensure
optimum run-time performance the code is always compiled to
provide stable functionality with reasonable memory useage. For
customers wishing to modify the compile time options you will
require the full source code package.
SigLib supports : 80x86™, Power PCs™, DEC Alpha™ and the following DSPs : TMS320C3X™, TMS320C4X™, TMS320C62X™*, TMS320C67X™, TMS320C64X™*. ADSP2106X (SHARC)™, ADSP-2116X™ and TigerSHARC™. StarCore™, MSC8101™, MSC8102™, LSILogic ZSP™, ARM, XScale.
Operating system support includes : DSP/BIOS II™, eXpressDSP™ (XDAIS), Windows NT/95/98/2000/ME/XP/CE/Mobile™, , Solaris™, VxWorks™, QNX™ and Linux™.
SigLib is compatible witht the following software : Gnuplot, Excel, Visual Basic, Agilent (formerly Hewlett-Packard) VEE™, National Instruments' LabVIEW™, Mathwork's MatLab™, Python, Java, Perl, C#, SoftIntegration's Ch™ C/C++ interpreter and many more.
