Preventing Soft Errors and Hardware Trojans in RISC-V Cores

Abstract: Soft errors in embedded systems' memories like single-event upsets and multiple-bit upsets lead to data and instruction corruption. Therefore, devices deployed in harsh environments, such as space, use fault-tolerant processors or redundancy methods to ensure critical application dependability. Another rising concern in secure, critical space applications is the possible introduction of hardware Trojans in an untrusted phase of the manufacturing process. Besides environmental side-effects, an adversary that ha… Show more

“…First of all, the processor internal memory structures, such as register files and L1/L2 caches, must be protected with error correction codes (ECC) [39]. Single-error correction and double-error detection (SECDED) Hamming codes are commonly considered in this context because of their moderate resource and performance overheads [40]. Likewise, the internal interconnect and external communication buses are subject to ECC protection.…”
