+<h2><a class="anchor" id="Introduction"></a>Introduction</h2>
+<p>The MATHLIB bundle comprises the Floating-Point Math Function Library package together with the software tools (SWTOOLS) package in bundle format to simplify the release procedure.</p>
+<hr/>
+<h2><a class="anchor" id="Starting"></a>Getting Started</h2>
+<p>The <a href="./docs/MATHLIB_Users_Manual.html">MATHLIB User's Manual</a> provides the documentation and references necessary to integrate MATHLIB Library routines into a development platform.</p>
+<hr/>
+<h2><a class="anchor" id="RTS"></a>Mathlib RTS</h2>
+<p>The Mathlib RTS package provides symbol names same as in standard RTS library. They can be used to replace standard RTS library function call.</p>

+<h2><a class="anchor" id="Validation"></a>Validation Information</h2>
+<p>This release was built and validated using the following tools:</p>
+<ul>
+<li>
+XDC Tools version: 3.50.05.12 </li>
+<li>
+RTSC Packaging Standard version: 2.0 </li>
+<li>
+C6000 Code Generation Tools version: 8.2.2 </li>
+<li>
+Code Composer Studio version: 8.1 </li>
+</ul>
+<p><b> Please note that the <a href="./docs/MATHLIB_c674x_TestReport.html">Test Report</a> was still based on Code Generation Tools 7.4.2.</b></p>

+<h2><a class="anchor" id="Known_Issues"></a>Known Issues</h2>
+<p></b></p>
+<p><b></b></p>
+<p><b></p>
+<ul>
+<li>C66 assembly implementation of Mathlib kernels is not available in this release. The assembly version of each kernel is exactly the same as the C version. Please ignore the profiling results for assembly version.</li>
+<li>Kernels acossp, asinsp, atanhdp and atanhsp are not included in the Mathlib RTS build, since C6000 RTS has faster implementation than Mathlib for these kernels.</li>

+<h3>Compatibility Keys</h3>
+<p></b></p>
+<p><b></b></p>
+<p><b> Compatibility keys serve two primary purposes:</b></p>
+<p><b> </p>
+<ol>
+<li>
+Enable tooling to identify incompatibilities between components </li>
+<li>
+Convey a level of compatibility between different releases to set end user expectations. </li>
+</ol>
+<p></b></p>
+<p><b> Each compatibility key is composed of 4 comma-delimited numbers - represented here by the letters M, S, R and P <code><b>[M,S,R,P]</b></code>. The table below provides a descriptive reference for compatibility key intention.</b></p>
+<p><b> </p>
+<table rules="all" frame="box" cellspacing="2" cellpadding="2" frame="void" width="80%">
+<caption align="bottom">Compatibility Key Reference</caption>

+<tr valign="top">
+<td>3 (<b>R</b>=Radix) </td><td>Introduction of new features </td><td>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 </td></tr>

+<h3>Versioning</h3>
+<p></b></p>
+<p><b></b></p>
+<p><b> Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b <code><b>[M.m.p.b]</b></code>. The table below provides a descriptive reference regarding package version numbering.</b></p>
