Introduction
The TI C6000 DSPLIB is an optimized DSP Function Library for C programmers. It includes many C-callable, optimized, general-purpose signal-processing routines. These routines are typically used in computationally-intensive real-time applications where optimal execution speed is critical.

Upgrade and Compatibility Information
This ti.dsplib release is backward compatible with the last released version.
Please note that the package compatibility keys are independent of XDC product release numbers.
Package compatibility keys are intended to:
- Enable tooling to identify incompatibilities between components, and
- Convey a level of compatibility between different releases to set end user expectations.
Package compatibility keys are composed of 4 comma-delimited numbers - M, S, R, P - where:
- M = Major - A difference in M indicates a break in compatibility. The package consumer is required to re-write its source code in order to use the package.
- S = Source - A difference in S indicates source compatibility. The package consumer’s source code doesn't require change, but does require a recompile.
- R = Radix - A difference in R indicates an introduction of new features, but compatibility with previous interfaces is not broken. If libraries are provided by the package, an application must re-link with the new libraries, but is not required to recompile its source.
- P = Patch - A difference in P indicates that only bugs have been fixed in the latest package and no new features have been introduced. If libraries are provided by the package, an application must re-link with the new libraries, but is not required to recompile its source.
