Latest Patents
Mrinal K Mandal holds 1 patent for his invention titled "Implementation of discrete wavelet transform using lifting steps." This patent focuses on creating hardware architectures for implementing lifting-based discrete wavelet transforms, including both 1-D and 2-D versions. The 1-D recursive architecture he developed exploits interdependencies among wavelet coefficients, achieving over 90% hardware utilization in typical cases. Additionally, the 1-D dual scan architecture processes two independent data streams simultaneously, achieving 100% datapath hardware utilization. The 2-D recursive architecture is approximately 25% faster than conventional implementations and requires minimal buffer storage. Furthermore, the 2-D dual scan architecture processes column and row transforms at the same time, maintaining a comparable memory buffer size to existing architectures.
