Signal Processing Library Features and Benefits

The Intel Signal Processing Library provides a rich set of generic functions (nearly 200) in standard DLLs and static libraries form. They are optimized for various Intel Architecture processors (the Intel486^™ processor, the Pentium^® processor, the Pentium processor with MMX^™ Technology, Pentium Pro processor, and the Pentium II processor). The computing power of the Pentium processor enables many signal processing functions that were done previously by add-in DSPs to be done natively on a host Intel Architecture processor. The library includes functions for FIR and IIR filters, fast Fourier transforms, tone generation, and many vector operations. The functions process 16-bit integer data, single- and double-precision, floating-point data, as well as their complex variations. Because MMX technology accelerates primarily integer arithmetic, the floating-point functions do not use MMX technology.

Here's a summary of the library's major features and benefits:

Feature	Benefit
Provides highly optimized processor-specific DLLs and static libraries.	Ensures optimal product performance and reduced time to market.
Provides C-Callable functions.	Allows you to use high-level language programming interface.
Provides custom DLL builder utility.	Ensures minimum memory footprint of DLL.
Provides both integer and floating point functions.	Supports a wide range of needs.
Detects a specific processor and loads a processor-specific DLL.	Allows you to use a single scalable executable file.
