Length: 2 days
Course Description
The focus of this training class is the Tensilica® FPX DSP Family.
This class provides an overview of the Tensilica FPX DSP architecture, instruction set, and programming model. It includes information on common Tensilica FPX DSP operations, how to write and optimize code, and how to use the advanced capabilities of the XT-CLANG C/C++ compiler. It provides essential skills necessary to develop and optimize baseband algorithms and kernels on the Tensilica FPX DSPs.
This class includes labs to give practical and hands-on experience with the DSP core, libraries, and software tools.
