Abstract :
The cell broadband engine (CBE) is a novel multi-core microprocessor designed to provide compact and high-performance processing capabilities for a wide range of applications. Real-time image processing applications with parallelism for large amounts of data are good examples to demonstrate the unique capabilities of the CBE. In this paper, we describe the evaluation of the performance for image processing using wavelet transforms on CBE. Our results show that the CBE is extremely efficient in this processing compared with commercially available processors, and thus, we conclude that the CBE is quite suitable for next generation large pixel formats, such as 4K/2K-digital cinema
