A high-throughput, memory efficient architecture for computing the tile-based 2D discrete wavelet transform for the JPEG2000
چکیده انگلیسی
In this paper, the design and implementation of an optimized hardware architecture in terms of speed and memory requirements for computing the tile-based 2D forward discrete wavelet transform for the JPEG2000 image compression standard, are described. The proposed architecture is based on a well-known architecture template for calculating the 2D forward discrete wavelet transform. This architecture is derived by replacing the filtering units by our previously published throughput-optimized ones and by developing a scheduling algorithm suited to the special features of our filtering units. The architecture exhibits high-performance characteristics due to the throughput-optimized filters. Also, the extra clock cycles required due to the tile-based version of the discrete wavelet transform are partially compensated by the proper scheduling of the filters. The developed scheduling algorithm results in reduced memory requirements compared with existing architectures.
