A survey on Reconfigurable Computing for Signal Processing Applications

Anne Pratoomtong

ECE734, Spring2002

motivation
Motivation
  • Adaptability under a variety of execution environment and constraints.
  • Development of a Robust-Large Scale signal Processing System for operation in complex non-stationary environment.
  • Cost and flexibility.
reconfigurable computing
Reconfigurable computing
  • Pre-Runtime Reconfigurable
  • Run-time Reconfigurable (RTR)

-FPGAs base RTR

-Structure Adaptive RTR

pre runtime reconfigurable
Pre-Runtime Reconfigurable
  • Computing system or device logic functionality and interconnect can be customized to suit a specific application through post-fabrication, user-defined programming.
  • Hardware Platform contains a mix variety of macro module with different characteristic connected via reconfigurable communication network.
run time reconfigurable rtr
Run-time Reconfigurable (RTR)
  • System logic and/or interconnect functionality can be modified during application execution.
  • Useful for DSP applications whose performance and functionality depend on run-time factors such as time-varying noise, runtime environment, computation resources available, or time-varying data set.
conclusion
Conclusion
  • RTR system does not fully utilize the ability to change the structure of the hardware reconfigurable component such as FPGA
  • Multiple computing hardware Vs Single computing hardware.
  • Hardware reconfiguration for the RTR system largely occur during the compile phase.
