### A survey on Reconfigurable Computing for Signal Processing Applications

Anne Pratoomtong

ECE734, Spring2002

Motivation Applications

- 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 Applications

- Pre-Runtime Reconfigurable
- Run-time Reconfigurable (RTR)
-FPGAs base RTR

-Structure Adaptive RTR

Pre-Runtime Reconfigurable Applications

- 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) Applications

- 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 Applications

- 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.
