Architectures for finite radon transform

Two VLSI architectures for the finite Radon transform are presented. The first is a reference architecture using memory blocks and the second is a memoryless architecture. The proposed architectures use 7×7 size image blocks and are prototyped for processing the CIF image sequence. The simulation and synthesis results show that the core speeds of the two proposed architectures are around 100 and 82 MHz, respectively.
