Self-Immunity Technique to Improve Register File Integrity against Soft Errors


Continuous shrinking in feature size, increasing power density etc, increase the vulnerability of microprocessors against soft errors even in terrestrial applications. The register file is one of the essential architectural components where soft errors can be very mischievous because errors may rapidly spread from there throughout the whole system. Thus, register files are recognized as one of the major concerns when it comes to reliability. The paper introduces Self-Immunity , a technique that improves the integrity of the register file with respect to soft errors. Based on the observation that a certain number of register bits are not always used to represent a value stored in a register.

The paper deals with the difficulty to exploit this obvious observation to enhance the register file integrity against soft errors. We show that our technique can reduce the vulnerability of the register file considerably while exhibiting smaller overhead in terms of area and power consumption compared to state-of-the-art in register file protection. For embedded systems under stringent cost constraints, where area, performance, power and reliability cannot be simply compromised, we propose a soft error mitigation technique for register files.

In this project for simulation we use Modelsim for logical verification, and further synthesizing it on Xilinx-ISE tool using target technology and performing placing & routing operation for system verification




  • Simulation: modelsim5.8c
  • Synthesis: Xilinx 9.1
