Design Optimizations for Tiled Partially Reconfigurable Systems

Markus Koester, Wayne Luk, Jens Hagemeyer, Mario Porrmann, Ulrich Ruckert
2011 IEEE Transactions on Very Large Scale Integration (vlsi) Systems  
We propose a design method for selecting suitable synthesis regions for the PR modules aiming to optimize their placement at run-time. ). J. Hagemeyer and M.  ...  In partially reconfigurable architectures, system components can be dynamically loaded and unloaded allowing resources to be shared over time.  ...  Since every PR module uses the same resources for the embedded macro, the macro is not modified at the run-time reconfiguration of a PR module.  ...

DBR: A Simple, Fast and Efficient Dynamic Network Reconfiguration Mechanism Based on Deadlock Recovery Scheme

Majed ValadBeigi
2012 International Journal of VLSI Design & Communication Systems  
Dynamic network reconfiguration is described as the process of replacing one routing function with another while the network keeps running.  ...  The mechanism which is referred to as DBR guarantees a deadlock-free reconfiguration based on wormhole switching (WS) and it does not require additional resources.  ...  On the other hand, traces are based on capturing the traffic when running real applications. Traces contain the source, destination, injection time and the size of each sent message.  ...

2021 Computers Materials & Continua  
In this paper, we developed the ESWI technique for detecting the wormhole attack while improving the performance and security.  ...  During data sharing, security is an important concern in such networks as they are prone to many threats, of which the deadliest is the wormhole attack.  ...  The detection algorithm is then run on the suspicious nodes, and the wormholes are detected by evaluating the hop-count time gap using the hop-time stamp.  ...

An FPGA-Based Dynamically Reconfigurable Platform: From Concept to Realization

Mateusz Majer
2006 2006 International Conference on Field Programmable Logic and Applications  
Using partial dynamic reconfiguration allows the main system to run uninterrupted during the reconfiguration process in addition to the reduced time for the reconfiguration process.  ...  Dynamically reconfigurable FPGA-based systems offer a new kind of flexibility such as on-demand computing, self-adaption and self-optimization capabilities by restructuring the hardware at run-time.  ...  This flexibility allows to place application modules at run-time in any available slot regardless of any I/O requirements.  ...

Path Concepts for a Reconfigurable Bit-Serial Synchronous Architecture [chapter]

Florian Dittmann, Achim Rettberg, Raphael Weber
2005 Lecture Notes in Computer Science  
This paper develops path concepts for the execution of different algorithms on a reconfigurable architecture.  ...  The application specificity of the basic version of the architecture can be overcome by so called routers, achieving a reconfigurable system.  ...  The concept of wormhole run time reconfiguration [7] relies on a distributed control scheme and therefore avoids central controllers.  ...

2021 2021 40th International Symposium on Reliable Distributed Systems (SRDS)  
ThreatAdaptive avoids this pitfall by proactively preparing the reconfiguration that may be triggered by an increasing threat when it optimizes its performance.  ...  Since replicas typically communicate with each other using an asynchronous network they cannot rely on consensus to decide how the system should be reconfigured.  ...  However, such a time synchronized response introduces significant complexity and overhead in the threat detector wormhole.  ...
