Length: 2 days
Course Description
This class provides detailed information about programming the Tensilica® ConnX BBE32EP Baseband Engine. The class provides an overview of the architecture and instruction set of the DSP, along with detailed information on how to write and optimize code. ConnX BBE32EP instructions for common DSP operations are presented in detail.
The class also covers tips and techniques for programming VLIW/SIMD machines like the ConnX BBE32EP and how to use the advanced capabilities of the XT-CLANG C/C++ compiler to generate better compiled code.
Demonstrations and labs give practical and hands-on experience with the DSP core, libraries, and software tools. This class provides the software developer or firmware engineer the essential skills necessary to develop and optimize baseband algorithms and kernels on the ConnX BBE32EP baseband DSP.
