The pipeline processor is a common paradigm for very high speed computing machinery. Pipeline processors provide high speed because their separate stages can operate concurrently, much as different people on a manufacturing assembly line work concurrently on material passing down the line. Although the concurrency of pipeline processors makes their design a demanding task, they can be found in ...

Micro-threads are small fragments of code based on loops, can be executed concurrently and the concurrency is described parametrically in the binary code. This thesis describes a microthreaded model of concurrency and illustrates the complete bottom-level design of its pipeline compared with the conventional MIPS pipeline. The simulations from a single microthreaded processor implemented in VHD...

Pipeline morphing is a simple but e ective technique for recon guring pipelined FPGA designs at run time. By overlapping computation and recon guration, the latency associated with emptying and re lling a pipeline can be avoided. We show how morphing can be applied to linear and mesh pipelines at both word-level and bit-level, and explain how this method can be implemented using Xilinx 6200 FPG...

A new class of latch controllers for asynchronous pipelines is presented. In addition to the standard operating mode, they can be configured in a collapsed mode, where the pipeline latches they control are kept transparent effectively joining the neighbouring pipeline stages into one. The depth of the resulting pipeline is dynamically adaptable, which can be used for power management of asynchr...

this paper presents results analyses of specific potential blowout scenarios for subsea oilpipelines between the coast of mainland of iran and khark island in the persian gulf. the analyses have been carried out with the sintef oil spill contingency and response (oscar) 3-dimensional model system.some hypothetical three-day blowout scenarios with light and heavy iranian oil have been investigat...

This paper discusses the current problems of assessing the pipeline integrity from an identification of the causal factors associated to various pipeline failure mechanisms and damages, such as corrosion, SCC, buckling, soil movement, and fatigue. The paper explains, furthermore, how emerging applications of Neutron Diffraction and Small Angle Neutron Scattering techniques can be carried out to...

Seismic-induced pore pressure and effective stresses in the saturated porous seabed under seismic loading are the main factors that govern the overall stability of submarine pipelines. In most of the previous investigations for the seismic-induced dynamic response around a submarine pipeline have been limited to two-dimension cases. In this paper, a three-dimensional finite element model includ...

Asynchronous pipelining is a form of parallelism in which processors execute diierent loop tasks (loop statements) as opposed to diierent loop iterations. An asynchronous pipeline schedule for a loop is an assignment of loop tasks to processors, plus an order on instances of tasks assigned to the same processor. This variant of pipelining is particularly relevant in distributed memory systems (...

Automated evidence-based gene building is a rapid and cost-effective way to provide reliable gene annotations on newly sequenced genomes. One of the limitations of evidence-based gene builders, however, is their requirement for transcriptional evidence-known proteins, full-length cDNAs, or expressed sequence tags (ESTs)-in the species of interest. This limitation is of particular concern for pl...
