3、nuous requirement to provide safe, low- cost, compact systems makes applications such as automotive more prone to increasing types of faults. This may result in increased system failure rates if not addressed correctly. While some of the faults are not permanent in nature, they can lead to malfuncti

One of the recommended schemes to tolerate faults is Triple Modular Redundancy (TMR). However, traditional TMR designs typical

In addition, common mode faults have always been a concern in TMR which their effects would be increasing in compact systems. Errors such as noise and offset that impact a TMR sensor input can potentially cause
6、common mode failures that lead to an entire system failure. In this paper, we introduce a new architecture and implementation for diverse TMR in a speed measurement system that would serve automotive cost and safety demands. Diversity TMR is achieved on a single chip by designing functionally identi

Three versions of a speed sensing application are implemented on a mixed-signal Programmable System on Chip (PSoC) from Cypress Semiconductors. We introduce errors that impact speed sensor signals as defi

In aviation system applications, such as the Boeing 777, TMR is implemented across all systems to ensure reliable operation 16. In addition, as
10、automotive systems are moving towards safety critical x-by-wire systems, fault tolerant methods such as TMR are needed due to high reliability requirements. As a result, as higher standards for reliability become necessary, the cost and unit size still need to be kept at a minimum.Two of the main co
11、nstraints in automotive are cost and size. The nature of the automotive industry being focused on mass produced products makes it more cost driven. Size is also critical to reduce the overall vehicle weight. Nevertheless, TMR has traditionally been obtained by triplication of hardware functionality
12、to reduce effects of common mode errors. Traditional approaches therefore are not the most cost or size effective for applications such as automotive. In addition, memory, power, and clock signals could be either shared or physically separate while using a single chip depending on how much separatio
13、n is required. Therefore, SoCs provide a more cost effective platform on which TMR can be implemented. More of those implementations have to be studied, however, to understand how much of an advantage is gained over existing schemes.As functional safety is becoming more prevalent in automotive appli

Functional safety standards, such as the ISo 26262, have been developed to establish a baseline, which applications are required to meet. The reliability of an embedded system unit in
15、volves many different aspects such as; sensors and/or actuators, software, environment and EMC, integrated circuits, and verification and validation.Automotive Safety Integrity Levels (ASILs) have been introduced as part of the recently released ISo26262 standard to evaluate the safety of automotive
16、 systems. System electronic modules are assigned an ASIL to indicate the level of safety a module can provide. ASIL D is the rating for the most dependable systems and ASIL A for the least dependable systems. Therefore to meet a certain ASIL level, a component design must incorporate all necessary fault detection and mitigation techniques required for achieving that level 15.In the ISo26262 TMR, among other fault mitigation methods, is highlighted as
