New CAD Framework Extends Simulation of Dynamically Reconfigurable Logic
نویسندگان
چکیده
New design methods and tools are needed to improve the process of designing dynamically reconfigurable logic. This paper reports on the revision and extension of Dynamic Circuit Switching (DCS), a CAD tool for specifying and simulating dynamically reconfigurable systems. The work introduces a new design framework, which exploits existing design practices where feasible, and proposes a new design flow for reconfigurable logic.

Modelling and Synthesis of Configuration Controllers for Dynamically Reconfigurable Logic Systems Using the DCS CAD Framework
The overheads contributed to a dynamically reconfigurable logic (DRL) design by its configuration controller can be prohibitive. Not only are the resource requirements and execution delays of the dynamic design adversely effected, but the time to redesign and test a configuration controller for every design iteration can be significant. We present a generic model of a configuration controller. ...
متن کاملVerification of Dynamically Reconfigurable Logic
Conventional FPGA design assumes a one-to-one mapping between circuits and device resources. In contrast, dynamically reconfigurable designs map many circuits to shared device resources. Each many-to-one mapping can be decomposed into sequences of temporal, one-to-one mappings. The verification of dynamically reconfigurable logic is complicated by the need to verify that each constituent mappin...
متن کاملCOSMOS : A System - Level Modelling and Simulation Framework for Coprocessor - Coupled
Dynamically reconfigurable systems demand complicated run-time management. Due to resource constraints and reconfiguration latencies, efficient reconfiguration strategies that can reduce the overhead cost of dynamic reconfiguration need to be studied. In this paper, we i) propose a reconfigurable task model which extends the classical real-time task model to support the additional states and la...
متن کاملA simulation tool for dynamically reconfigurable field programmable gate arrays
The emergence of static memory–based FPGAs that are capable of being dynamically reconfigured, i.e. partially reconfigured while active, has resulted in research into new methods of digital systems synthesis. At present, however, there are virtually no CAD tools to support the design of digital systems using dynamic reconfiguration. This paper reports on an investigation of new simulation too...
متن کاملTinyOS Extensions for a Wireless Sensor Network Node Based on a Dynamically Reconfigurable Processor
Wireless sensor networks (WSNs) present design issues and challenges in both hardware and software platform development. This paper presents the implementation of a hardware-dependent component library that extends TinyOS in order to create an abstraction layer on top of a dynamically reconfigurable hardware architecture. Such hardware architecture is based on a SPARC-compliant processor and it...
