<h3 class="version">Version1.0.10 </h3><p><b>Introduction</b></p>
|
|
<p>This user manual describes the CMSIS DSP software library, a suite of common signal processing functions for use on Cortex-M processor based devices.</p>
|
|
<p>The library is divided into a number of modules each covering a specific category:</p>
|
|
<ul>
|
|
<li>Basic math functions</li>
|
|
<li>Fast math functions</li>
|
|
<li>Complex math functions</li>
|
|
<li>Filters</li>
|
|
<li>Matrix functions</li>
|
|
<li>Transforms</li>
|
|
<li>Motor control functions</li>
|
|
<li>Statistical functions</li>
|
|
<li>Support functions</li>
|
|
<li>Interpolation functions</li>
|
|
</ul>
|
|
<p>The library has separate functions for operating on 8-bit integers, 16-bit integers, 32-bit integer and 32-bit floating-point values.</p>
|
|
<p><b>Processor Support</b></p>
|
|
<p>The library is completely written in C and is fully CMSIS compliant. High performance is achieved through maximum use of Cortex-M4 intrinsics.</p>
|
|
<p>The supplied library source code also builds and runs on the Cortex-M3 and Cortex-M0 processor, with the DSP intrinsics being emulated through software.</p>
|
|
<p><b>Toolchain Support</b></p>
|
|
<p>The library has been developed and tested with MDK-ARM version 4.21. The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly.</p>
|
|
<p><b>Using the Library</b></p>
|
|
<p>The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.</p>
|
|
<ul>
|
|
<li>arm_cortexM4lf_math.lib (Little endian and Floating Point Unit on Cortex-M4)</li>
|
|
<li>arm_cortexM4bf_math.lib (Big endian and Floating Point Unit on Cortex-M4)</li>
|
|
<li>arm_cortexM4l_math.lib (Little endian on Cortex-M4)</li>
|
|
<li>arm_cortexM4b_math.lib (Big endian on Cortex-M4)</li>
|
|
<li>arm_cortexM3l_math.lib (Little endian on Cortex-M3)</li>
|
|
<li>arm_cortexM3b_math.lib (Big endian on Cortex-M3)</li>
|
|
<li>arm_cortexM0l_math.lib (Little endian on Cortex-M0)</li>
|
|
<li>arm_cortexM0b_math.lib (Big endian on Cortex-M3)</li>
|
|
</ul>
|
|
<p>The library functions are declared in the public file <code><a class="el" href="arm__math_8h.html">arm_math.h</a></code> which is placed in the <code>Include</code> folder. Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single public header file <code> <a class="el" href="arm__math_8h.html">arm_math.h</a></code> for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants. Define the appropriate pre processor MACRO ARM_MATH_CM4 or ARM_MATH_CM3 or ARM_MATH_CM0 depending on the target processor in the application.</p>
|
|
<p><b>Examples</b></p>
|
|
<p>The library ships with a number of examples which demonstrate how to use the library functions.</p>
|
|
<p><b>Building the Library</b></p>
|
|
<p>The library installer contains project files to re build libraries on MDK Tool chain in the <code>CMSIS</code> folder.</p>
|
|
<ul>
|
|
<li>arm_cortexM0b_math.uvproj</li>
|
|
<li>arm_cortexM0l_math.uvproj</li>
|
|
<li>arm_cortexM3b_math.uvproj</li>
|
|
<li>arm_cortexM3l_math.uvproj</li>
|
|
<li>arm_cortexM4b_math.uvproj</li>
|
|
<li>arm_cortexM4l_math.uvproj</li>
|
|
<li>arm_cortexM4bf_math.uvproj</li>
|
|
<li>arm_cortexM4lf_math.uvproj</li>
|
|
</ul>
|
|
<p>Each library project have differant pre-processor macros.</p>
|
|
<p><b>ARM_MATH_CMx:</b> Define macro ARM_MATH_CM4 for building the library on Cortex-M4 target, ARM_MATH_CM3 for building library on Cortex-M3 target and ARM_MATH_CM0 for building library on cortex-M0 target.</p>
|
|
<p><b>ARM_MATH_BIG_ENDIAN:</b> Define macro ARM_MATH_BIG_ENDIAN to build the library for big endian targets. By default library builds for little endian targets.</p>
|
|
<p><b>ARM_MATH_MATRIX_CHECK:</b> Define macro for checking on the input and output sizes of matrices</p>
|
|
<p><b>ARM_MATH_ROUNDING:</b> Define macro for rounding on support functions</p>
|
|
<p><b>__FPU_PRESENT:</b> Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries</p>
|
|
<p>The project can be built by opening the appropriate project in MDK-ARM 4.21 chain and defining the optional pre processor MACROs detailed above.</p>
