| Abstract(in English) | We propose architecture of Fast Hadamard Transform (FHT), one of the orthogonal transform for digital signals. Our proposed architecture can reduce parallelism of FHT butterfly to 1/2^n dynamically. Also, we describe a design method for implementing proposed architecture on dynamically reconfigurable devices. Therefore, our FHT system has dynamical alterability of dimension, number of signals, and parallelism. This alterability enables the system to adapt itself to outside requirements changing. We implemented the architecture on a dynamically reconfigurable device PCA-1 with single parallelism. As the result of implementation and evaluation, our system has achieved higher speed performance than our previous work. |
