Introduction to the TI C67x DSPLIB

1.1 Introduction to the TI C67x DSPLIB
1-2
The TI C67x DSPLIB is an optimized DSP Function Library for C programmers
using TMS320C67x devices. It includes C-callable, assembly-optimized gen-
eral-purpose signal-processing routines. These routines are typically used in
computationally intensive real-time applications where optimal execution
speed is critical. By using these routines, you can achieve execution speeds
considerably faster than equivalent code written in standard ANSI C language.
In addition, by providing ready-to-use DSP functions, TI DSPLIB can signifi-
cantly shorten your DSP application development time.
The TI DSPLIB includes commonly used DSP routines. Source code is pro-
vided that allows you to modify functions to match your specific needs.
The routines contained in the library are organized into the following seven dif-
ferent functional categories:
-
Adaptive filtering
J
DSPF_sp_lms
-
Correlation

DSPF_sp_autocor
