Dual-core reconfigurable demosaicing engine for next generation of portable camera systems

This paper presents a high performance dual-core reconfigurable processor implementation methodology for a demosaicing system that targets next generation camera systems. The implementation methodology is based on dual-core architecture with coarse-grained dynamically reconfigurable processors. The demosaicing system adopts Freeman´s algorithm that has been partitioned and mapped onto two customized and tailored heterogeneous processor cores. The demosaicing engine´s implementation has been optimized by compilation techniques and special approaches for the targeting processor. Simulation results demonstrate that the resulting demosaicing system provides high throughput reaches up to 241.6Mpixels/s, which represents a 1.82x speedup compared to a single-core implementation.
