A Vector and Parallel Library for Image and Signal Processing
Home >> Standard Math Library
SKY's Standard Math Library (SML) employs intelligent software technology to achieve
transparent portability, ease-of-use, and performance in a library of math, image, and
signal processing functions. Developers no longer have to choose between developing
code optimized for performance or developing for portability. The advanced functionality
of the SML provides SKY customers with truly portable high performance code.
SML achieves performance and portability through a unique two-level architecture. All
the functions that require information specific to a processor or an architecture are
collected in a low-level library. Access to those high performance functions is provided
by a portable high-level interface that is both processor independent and architecture
independent. A single high-level function call in the application automatically utilizes
one of several low-level variations of that function: cache source, cache destination, or
cache both; single or double precision. At compile time SKY's intelligent compiler
technology chooses the function based upon context or responding to compiler switches.
The integrity and portability of the source code are maintained and the developer is freed
from tracking the low-level detail. Beyond ease-of-use, this enables software reuse,
leveraging today's software investment for tomorrow.
SKY's SML eliminates the painstaking, time-consuming process of optimizing an application
by combining a high-level interface for ease-of-use and portability, and a low-level library
for ultimate performance. The result is a significant advantage in reduced time-to-deployment
and overall software life-cycle costs.
Standard Math Library Timings
SKY provides timing reports for Merlin. Timings are based upon the utilization of one of the
four 500 MHz MPC7410 PowerPC processors on Merlin. Following are sample timings, for the complete
list of special timings including 1 and 2D FFTs, FIR filters, and matrix functions contact your
SKY representative or email us directly.
