Choosing processors that address the most stringent ASIL automotive functional safety requirements

Choosing processors that address the most stringent ASIL automotive functional safety requirements

The days when it was sufficient to 'inspect in' quality by checking the product at the end of the production process are largely behind us. Nowadays, far greater levels of quality are achieved by controlling the actual production process more closely - usually leading to a reduction in overall operating costs.

While the odd defect may 'sneak through' the risks are usually tolerable, and the costs of further defect reduction are prohibitive. Generally, this level of quality is commercially acceptable for most products - if you buy an appliance that has a defect then you return it for a replacement.

However, when we are dealing with life-critical systems, such as the Advanced Driver Assistance Systems (ADAS) in modern vehicles, the 'odd defect' can cost a life. Clearly the stakes are much higher and, accordingly, a much more rigorous approach is required.

Safety within the automotive industry is governed by the ASIL (Automotive Safety Integration Level) process. This has four levels of severity (A to D, where D is the most stringent). ASIL is defined and controlled by the international standard ISO 26262, which is an adaption of the IEC 61508 standard that manages SIL levels in industrial equipment.

Functional safety systems, such as ASIL, control every aspect of the product, beginning at the very start of its life (the writing of the requirements specification falls under the ASIL scope). Every aspect of product design, development, production, operation, servicing and decommissioning require hazard analysis and risk assessment.

Since systems such as collision avoidance and pedestrian detection are considered safety-critical they must meet the appropriate ASIL specification. Toshiba has developed its image recognition processor families such as the TMPV7608XBG using its own ISO26262-certified process flow, and has designed the devices to satisfy the requirements for ASIL-C/D (Automotive Safety Integrity Level) systems.
