The services provided by the DSP run-time library include support for general-purpose signal processing such as companders, filters, and Fast Fourier Transform (FFT) functions. All these services are Analog Devices extensions to ANSI standard C. "</p><p>Difference from the original library:</p><ul><li class="level1"><div class="li"> No math.h: The original library contains math function overlapping with uClibc math library. To avoid confusion, these functions are removed.</div></li></ul><p> Please use uClibc math library. Also please include “-lm” in the LDFLAGS, since “libbfdsp” depends on this library. </p><ul><li class="level1"><div class="li"> C++ not tested yet.</div></li></ul><p> The DSP library is documented at <a href="http://www.analog.com/UploadedFiles/Associated_Docs/613293690438645_Blackfin_comp_man.pdf" class="urlextern" title="http://www.analog.com/UploadedFiles/Associated_Docs/613293690438645_Blackfin_comp_man.pdf" rel="nofollow">C/C++ Compiler and Library Manual for Blackfin Processors</a> in chapter 4, DSP Run Time Library.</p></div></body></html>⌨️ 快捷键说明
