Inter-kernel data reuse and pipelining on chip-multiprocessors for multimedia applications
The increasing demand for low power and high performance multimedia embedded systems has motivated the need for effective solutions to satisfy application bandwidth and latency requirements under a tight power budget. As technology scales, it is imperative that applications are optimized to take full advantage of the underlying resources and meet both power and performance requirements. We propose a methodology capable of discovering and enabling parallelism opportunities via code transformations, efficiently distributing the computational load across resources, and minimizing unnecessary data transfers. Our approach decomposes the application's tasks into smaller units of computations called kernels, which are distributed and pipelined across the different processing resources. We exploit the ideas of inter-kernel data reuse to minimize unnecessary data transfers between kernels and early execution edges to drive performance. Our experimental results on a JPEG2000 case study show...
