Luca Breveglieri, Vincenzo Piuri, M. Rona, Earl E. Swartzlander · 2002
The 1-Dimensional Discrete Wavelet Transform is a powerful DSP technique for several application areas. Dedicated VLSI processors are often required by real-time applications due to the high amount of arithmetic operations; the circuit complexity is usually a relevant constraint for several low-cost applications as well as for complex systems having strong dimensional limits on the implementation (e.g., in aerospace applications). This paper presents the architectural design of a low-latency bit-serial 1-Dimensional Wavelet Transform Processor.
