Scratchpad memory (SPM) is widely used in modern embedded processors to overcome the limitations of cache memory. The high vulnerability of SPM to soft errors, however, limits its usage in safety-critical applications. This paper proposes an efficient fault-tolerant scheme, called cache-assisted duplicated SPM (CADS), to protect SPM against soft errors. The main aim of CADS is to utilize cache memory...
Predictability, energy consumption, area and reliability are the major concerns in embedded systems. Using scratchpad memories (SPMs) instead of cache memories play an increasing role to satisfy these concerns. Both cache and SPM as on-chip SRAM memories are highly vulnerable to soft errors and as they contain the most frequently used blocks of the program, their errors can easily propagate in system...
Ever Increasing use of commercial off-the-shelf (COTS) processors to reduce cost and time to market in embedded systems has brought significant challenges in error detection and recovery methods employing in such systems. This paper presents a software based control flow error detection and correction technique, so called branch TMR (BTMR), suitable for use in COTS-based embedded systems. In BTMR...
