String matching on multicontext FPGAs using self-reconfiguration

Reetinder P. S. Sidhu, Alessandro Mei, Viktor K. Prasanna
1999 Proceedings of the 1999 ACM/SIGDA seventh international symposium on Field programmable gate arrays - FPGA '99  
The key idea is to design and map logic onto a multicontext FPGA that in turn maps problem instance dependent logic onto other contexts of the same FPGA.  ...  We implement the KMP algorithm on a conventional FPGA (Xilinx XC 6216) and use it to obtain accurate estimates of performance on a multicontext device.  ...  We now compare the mapping time (TM + TM E ) of the proposed multicontext FPGA approach with other approaches.  ...

HW/SW codesign techniques for dynamically reconfigurable architectures

J. Noguera, R.M. Badia
2002 IEEE Transactions on Very Large Scale Integration (vlsi) Systems  
In this paper, we present three main contributions: 1) a novel HW/SW codesign methodology with dynamic scheduling for discrete event systems using dynamically reconfigurable architectures; 2) a new dynamic  ...  In addition, all previous approaches to reconfigurable computing multicontext scheduling are based on static-scheduling techniques.  ...  And even more important, these estimators do not take into account the features or parameters of the dynamically reconfigurable architecture (reconfiguration time, number of contexts, etc).  ...

Query-Based Multicontexts for Knowledge Base Browsing: An Evaluation [chapter]

Julien Tane, Philipp Cimiano, Pascal Hitzler
2006 Lecture Notes in Computer Science  
In [7] , we introduced the query-based multicontext theory, which allows to define a virtual space of views on ontological data. Each view is then materialised as a formal context.  ...  On the other hand, it exposes the preliminary evaluation of the visualisation of formal contexts by comparing the display of a lattice to two other approaches based on trees and graphs.  ...  Definition: Query-based Multicontext Each of the views of the system corresponds to a triple p of queries which can be interpreted to a formal context by means of an evaluation function κ. p := (q 1 ,  ...

A cost-effective context memory structure for dynamically reconfigurable processors

M. Suzuki, Y. Hasegawa, V.M. Tuan, S. Abe, H. Amano
2006 Proceedings 20th IEEE International Parallel & Distributed Processing Symposium  
Multicontext reconfigurable processors can switch its configuration in a single clock cycle by providing a context memory in each of the processing elements.  ...  The template configuration method which extends this idea harnesses the power of multicontext devices by storing basic contexts as templates and combining them to form the actual contexts.  ...  Our future work is to apply the method to a system with a more coarser grained PE.  ...

A Survey on Dynamically Reconfigurable Processors

2006 IEICE transactions on communications  
Hideharu AMANO †a) , Member SUMMARY Dynamically reconfigurable processors are consisting of an array of processing elements whose functions and interconnections can be dynamically changed. 9 commercial systems  ...  Although context switching can be done with a clock cycle in multicontext devices, the area of each PE is increased with the distributed context memory.  ...  Finally, the most important difference is that the setting of switching matrix can be changed by dynamic reconfiguration, especially, every clock cycle in multicontext devices.  ...
