DSP Run-Time Library Reference
DSP Run-Time Library Reference
This section provides descriptions of the DSP run-time library functions.
Notation Conventions
An interval of numbers is indicated by the minimum and maximum, sepa-
rated by a comma, and enclosed in two square brackets, two parentheses,
or one of each. A square bracket indicates that the endpoint is included in
the set of numbers; a parenthesis indicates that the endpoint is not
included.
The reference pages for the library functions use the following format.
• Name and purpose of the function
• Synopsis — Required header file and functional prototype. When
the functionality is provided for several data types (for example,
float, double, or fract16), several prototypes are given.
• Description — Function specification
• Algorithm — High level mathematical representation of the
function
• Domain — Range of values supported by the function
• Notes — Other miscellaneous notations
For some functions, the interface is presented using the "K&R" style for
ease of documentation. An ANSI C prototype is provided in the header
file.
