20 <h2><a class="anchor" name="General_Info"></a>Introduction</h2>
21 <p>
22 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.<p>

55 <h2><a class="anchor" name="Compatibility"></a>Upgrade and Compatibility Information</h2>
56 <p>
57 This <b>ti.dsplib</b> release is backward compatible with the last released version.<p>
58 Please note that the package compatibility keys are independent of XDC product release numbers.<p>
59 Package compatibility keys are intended to:<p>
60 <ol type=1>
61 <li>Enable tooling to identify incompatibilities between components, and</li><li>Convey a level of compatibility between different releases to set end user expectations.</li></ol>
62 <p>
63 Package compatibility keys are composed of 4 comma-delimited numbers - M, S, R, P - where:<p>
64 <ul>
65 <li><b>M = Major</b> - 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.</li><li><b>S = Source</b> - A difference in S indicates source compatibility. The package consumer\92s source code doesn't require change, but does require a recompile.</li><li><b>R = Radix</b> - 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.</li><li><b>P = Patch</b> - 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.</li></ul>
