Platform based design for a multimedia Motion JPEG decoder case study

In recent years, computational requirements for embedded applications are increasing exponentially. This complexity, coupled with constantly evolving specifications, has forced designers to consider intrinsically flexible implementations. For this reason, heterogeneous multiprocessor architectural platforms are gaining prevalence for embedded systems. Deploying applications typical of multimedia domains is difficult, not only due to the heterogeneous parallelism in the platforms, but also due to the performance constraints that typify these systems. In this paradigm, the digital system-on-a-chip (SoC) platform-based design environment for shared memory multiple instructions multiple data (MIMD) architectures (Disydent) is used. The applicability of the Disydent design flow to systems in the multimedia domain is illustrated. The case studied consists in deploying a motion JPEG decoder application onto a configurable prototype of a multiprocessor MIPS platform architecture.
