Abstract

Wavelet transform is an important signal analysis tool. However, it is not well-supported like the Fourier transform in embedded systems domain. Implementations of the wavelet transform in the embedded systems domain are generally concentrated on specific applications like image/video processing, etc. In this paper, we present two fixed-point implementation frameworks for the discrete wavelet transform for real-time applications of one-dimensional embedded signal processing. These are based on the convolution and the lifting scheme. The implementation frameworks are realized and tested using 16-bit fixed-point Texas Instruments TMS320VC5510 DSP. Application examples, performance statistics and future scopes are presented in the scope of this paper.
