Length: 2 days
Course Description
The focus of this training class is the Tensilica® FloatingPoint DSP Family.
This class provides an overview of the Tensilica FloatingPoint DSP architecture, instruction set, and programming model. It includes information on common Tensilica FloatingPoint 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, radar/lidar, image processing, and neural network algorithms and kernels on the Tensilica FloatingPoint DSPs.
This class includes labs to give practical and hands-on experience with the DSP core, libraries, and software tools.
