4 DSP RUN-TIME LIBRARY

This chapter describes the DSP run-time library which contains a broad
collection of functions that are commonly required by signal processing
applications. The services provided by the library include support for gen-
eral purpose signal processing such as companders, filters, and Fast
Fourier Transform (FFT) functions. All these services are Analog Devices
extensions to ANSI standard C. These functions are in addition to the
C/C++ run-time library functions that are described in Chapter 3,
"C/C++ Run-Time
For more information on the algorithms on which many of DSP run-time
library's math functions are based, see the Cody and Waite text "Software
Manual for the Elementary Functions" from Prentice Hall (1980).
