ABSTRACT
This paper discusses architectural issues arising from the use of dynamic reconfiguration and shows a possible use of dynamic reconfiguration to extend and accelerate a computation performed in system-on-a-chip designs with microprocessors with fixed instruction sets. Further a sample application is discussed that uses a dynamically reconfigurable FPGA to implement different floating-point calculations in hardware, reconfigured as required by the execution of the user code. The implementation data for two dynamically reconfigurable platforms available on the market - the Xilinx Virtex2 family FPGAs and the Atmel FPSLIC family FPGAs - is compared in terms of resource requirements, operating frequency, and power consumption.

Dynamic Reconfiguration Technologies Based on FPGA in Software Defined Radio System
Partial Reconfiguration (PR) is a method for Field Programmable Gate Array (FPGA) designs which allows multiple applications to time-share a portion of an FPGA while the rest of the device continues to operate unaffected. Using this strategy, the ...
