In this paper we present the different modelling problems which a Digital Signal Processing (DSP) application designer has to tackle while refining an abstract specification relying on coarse grain data (e.g. matrices) toward a hardware implementation model relying on fine grain data (e.g. scalar). To address this problematic, we propose a modelling framework which can be used to refine an algo...

Kodak fine grain positive photographic emulsion has characteristics of speed, contrast, and grain size favorable for recording the low contrast electron images Of thin-sectioned biological material. In addition, the rendition of detail by this emulsion appears to be of superior quality to that obtained on conventional lantern slide emulsions. By special order, Eastman Kodak provides fine grain ...

A fine grain, relaxor-based piezoelectric ceramic 0.7 Pb(Mg(1/3)Nb(2/3))O3-0.3PbTiO3 (PMN-30% PT) has been investigated, which was fabricated using the columbite precursor method. The complete set of electromechanical properties of the piezoceramic at room temperature is determined using a combination of ultrasonic and resonance techniques. This fine-grain ceramic (grain size < or = 2.5 microm)...

Instruction–level multithreading is an architectural approach to tolerating long–latency memory accesses and synchronization delays in distributed–memory systems. The paper presents a timed Petri net model of a fine–grain multithreaded distributed–memory multiprocessor system at the instruction execution level, and illustrates performance analysis by results obtained from simulation of the deri...

Symmetric multiprocessors (SMPs) connected with low-latency networks provide attractive building blocks for software distributed shared memory systems. Two distinct approaches have been used: the fine-grain approach that instruments application loads and stores to support a small coherence granularity, and the coarse-grain approach based on virtual memory hardware that provides coherence at a p...

Given the proliferation of layered, multicoreand SMT-based architectures, it is imperative to deploy and evaluate important, multi-level, scientific computing codes, such as meshing algorithms, on these systems. We focus on Parallel Constrained Delaunay Mesh (PCDM) generation. We exploit coarse-grain parallelism at the subdomain level, medium-grain at the cavity level and fine-grain at the elem...

In this paper, we propose a method for speeding-up Digital Signal Processing applications by partitioning them between the reconfigurable hardware blocks of different granularity and mapping critical parts of applications on coarse-grain reconfigurable hardware. The reconfigurable hardware blocks are embedded in a heterogeneous reconfigurable system architecture. The fine-grain part is implemen...

Multi-grain parallelizing scheme is one of effective parallelizing schemes which exploits various level parallelism: coarse-grain(macro-dataflow), medium-grain(loop level parallelizing) and near-fine-grain(statements parallelizing) from a sequential program. A multi-processor ASCA is designed for efficient execution of multi-grain parallelizing program. A processing element called MAPLE are mai...
