Data mining, bioinformatics, knowledge discovery, social network analysis, are emerging irregular applications that exploits data structures based on pointers or linked lists, such as graphs, unbalanced trees or unstructured grids. These applications are characterized by unpredictable memory accesses and generally are memory bandwidth bound, but also presents large amounts of inherent dynamic parallelism...
Increasing the degree of speculative execution in application-specific micro architectures, which can be generated for reconfigurable computers from high-level code using techniques such as PreCoRe, also leads to an increased pressure on the memory system. The RAP approach introduced here describes and evaluates application specific micro architectural techniques to reduce the impact of aggressively...
Loops are an important source of optimization. In this paper, we propose a new technique for optimizing loops that contain kernels mapped on a reconfigurable fabric. We assume the Molen machine organization and programming paradigm as our framework. The method we propose extends our previous work on loop unrolling for reconfigurable architectures by combining unrolling with shifting to relocate the...
