Signal Processing Examples Using the TMS320C67x DSP Library (Rev. A)

The TMS320C67x™ digital signal processing library (DSPLIB) provides a set of C-callable, assembly-optimized functions commonly used in signal processing applications, e.g., filtering and transform. The DSPLIB includes several functions for each processing category, based on the input parameter conditions, to provide parameter-specific optimal performance. Therefore, it is important to understand the differences and requirements of the functions in each category. This application report presents the usage and performance of three key signal processing categories, i.e., finite impulse response (FIR), bi-quadratic infinite impulse response (IIR), and fast Fourier transform (FFT), to help users better utilize DSPLIB in their system development.
