TMS320C3x/'C4x
Optimized DSP Library
by Wideband Computers, Inc.

Software Overview

The Wideband TMS320C3x/'C4x Optimized DSP Library contains over 250 assembly language, C-callable, 
vector, scalar math and DSP routines used in compute-intensive scientific and engineering 
applications. Each routine is hand-coded in TMS320 assembler to take maximum advantage of the 
TMS320 architecture, ensuring optimum execution speeds. The library ensures 7.75 digits of 
floating-point precision, supports intelligent vector data striding, and allows users to 
individually link routines thus saving valuable embedded space. Each routine is also shipped with a 
C data routine. The library is inexpensive, fully tested, and easy to work with. No run-time 
licensing is required after purchase.
Embedded programmers, DSP system engineers, and hardware developers may save weeks of development 
time by embedding just a few routines from the Wideband Library in their C code, thus ensuring fast 
and effecient execution time along with quality software implementation. This translates into real 
savings.
