JPEG XR encoder implementation on a heterogeneous multiprocessor system

摘要

Fast evolving digital imaging on embedded devices imposes need for fast, energy efficient and flexible encoder implementation. In this paper we present fully software implementation of JPEG XR encoder on heterogeneous multiprocessor platform consisting of one VLIW+SIMD processor used for compute-intensive parts of the algorithm. Achieved performance is between fully software implementation on general purpose processor and fully hardware implementation, with flexibility of fully software implementation.
