The present day technological advancement has resulted in multiple core processors coming into desktops, handhelds, servers and workstations. This is because the present day applications and users demand huge computing power and interactivity. Both of these reasons have resulted in a total design shift in the way the processors are designed and developed. However the change in the hardware has not been accompanied with the change in the way the software has to be written for these multicore processors. In this paper, we intend to provide the integration of OpenGL programs on a platform which supports multicore processors. The paper would result in clear understanding how graphics pipelines can be implemented on multi-core processors to achieve higher computational speeds up with highest thread granularity. The impacts of using too much parallelism are also discussed. An OpenMP API for the thread scheduling of parallel task is discussed in this paper. The tool Intel VTune Performance Analyzer is used to find the hotspots and for software optimization. Comparing both the serial and parallel execution of graphics code shows encouraging results and it has been found that the increase in frame rate has resulted due to parallel programming techniques.

Video coding is one of the most demanding applications, in terms of computational cost, for portable multimedia terminals. In the last years, the new video coding standards, like High Efficiency Video Coding (HEVC), and the increasing resolutions of video codecs have overtaken the capacities of the single core processors in embedded systems. In consequence, multicore architectures are used in current multimedia systems. Besides, new methodologies and frameworks are arising to speed-up the design cycle. In this paper, a methodology based on the Reconfigurable Video Coding CAL Actor Language (RVC-CAL) and the OpenMP API has been used to implement an HEVC decoder based on a multicore DSP. A RVC-CAL description of the HEVC decoder has been used as starting point. The Open RVC-CAL compiler framework (Orcc) has been used to generate C-code from the RVC-CAL specification. This code and the OpenMP library have been ported to the multicore DSP environment. Decoders running on 1, 2, 3 and 4 cores have been tested. Also, the multi DSP based HEVC decoder has been compared with other implementations based on multicore GPPs 1 .
