VSIPL DSP Libraries

The Vector, Signal, and Image Processing Library (VSIPL) is a standardised set of functions and an open application programming interface (API) that provides portable computational middleware for signal and image processing applications. It was developed by a team of hardware manufacturers, software developers, academics, and US government research centres. The API is designed to be totally processor neutral while allowing extensive processor-specific optimisations beneath the surface.

Scope of the VSIPL API:

• support functions
• scalar functions (mathematical functions, complex arithmetic)
• elementwise functions (mathematical functions, arithmetic, comparison, selection, random number generation)
• signal processing functions (FFT, windows, filters, convolution, correlation, histogram)
• linear algebra functions: (vector and matrix products, matrix decompositions, equation solvers).

See https://www.omg.org/spec/VSIPL/ for more details.

We provide highly optimised VSIPL libraries for:

• ARM A53, A57, and A72
• PPC T2080
• PPC T2081
• PPC T4240
• Intel AVX512
• Intel Phi
• Intel AVX2
• Intel AVX
• Intel SSE

The VSIPL API includes definitions of:

• Core Lite
• Core
• Full
• Double Precision Full

Multi-threaded versions for shared memory systems are also available - the parallelism is completely transparent to the end-user and no changes are required to existing VSIPL code.
