Data-parallel Digital Signal Processors: Algorithm Mapping, Architecture Scaling and Workload Adaptation streaming video, image processing in embedded applications and signal processing in high-speed wireless communications are driving a need for high performance digital signal processors (DSPs) with real-time processing. inter-cluster. Abstract: The broad introduction of multi-core processors into computing has brought a great opportunity to deploy computationally demanding applications such as signal and image processing on parallel computing platforms. However it is not an easy task to decompose a computational problem into sub-problems to explore the massive parallelism provided by multi-core processors.
in parallel and pipeline modes. Data streams may split, merge, exchange or cross information. This is called multipipelined execution. It is, therefore, im-portant to represent signal and image processing algorithms in multipipelined form to be properly mapped onto the homogeneous computing structure. Abstract: Many digital signal and image processing algorithms can be speeded up by executing them in parallel on multiple processors. The speed of parallel execution is limited by the need for communication and synchronization between processors. In this paper, we present a paradigm for parallel processing that we call the block data flow paradigm (BDFP). In this research we also tried to describe the role of parallel image processing in the field of medical imaging. algorithm with p processors and Ts (n,1) Digital signal processor. gershausen, önfeld and , “Mapping complex image processing algorithms onto heterogeneous multi-processors regarding architecture dependent performance parameters”, Intnl.

Unfortunately, simply porting a software algorithm onto an FPGA often gives disappointing results, because many image processing algorithms have been optimised for a serial processor. It is usually necessary to transform the algorithm to efﬁciently exploit the parallelism and resources available on an FPGA. Different software realizations of the dataflow in the algorithms can affect the performance of stream processors by greater than an order-of-magnitude. The thesis first presents the design of signal processing algorithms that map efficiently on stream processors by parallelizing the algorithms and by re-ordering the flow of data.
