Abstract:

The need for understanding how to distribute computations across multiple cores, have obviously increased in the multicore era. Scheduling the functional blocks of an application for concurrent execution requires not only a good understanding of data dependencies, but also a structured way to describe the intended scheduling. In this paper we describe how the Canals language and its scheduling framework can be used for the purpose of scheduling and executing legacy code. Additionally a set of translation guidelines for translating RVC-CAL applications into Canals are presented. The proposed approaches are applied to an existing MPEG-4 Simple Profile decoder for evaluation purposes. The inverse discrete cosine transform (IDCT) is accelerated by the means of OpenCL.
