Abstract :
The issue of soft errors is an important emerging concern in the design and implementation of future microprocessors. The authors examine the impact of soft errors on two different microarchitectures: a DLX processor for embedded applications and a high-performance alpha processor. The results contrast impact of soft errors on combinational and sequential logic, identify the most vulnerable units, and assess soft error impact on the application.
