Fast Integer Arithmetic Wavelet Transform properties and application in FPGA/DSP system

The new fully integer processing of the wavelet scheme compression enables very fast application and thus it can be very useful for application in real-time systems. The most important property of this concept seems to be the possibility of simple and fast application into FPGA chip. The new Fast Integer Arithmetic Wavelet Transform (FIAWT) can be a very useful tool to compute DWT (and non-decimated DWT) for the time-restricted systems (real-time data processing) e.g. Data Acquisition (DAQ) systems with a waveform recorder. In this paper the authors show some important aspects of FIAWT. The application example (FPGA/DSP) in the ICARUS¹ DAQ system for compression with signal recognition is included as part of this paper.
