Functional safety involves [i] the detection of a potentially dangerous condition, and [ii] the activation of a protective / corrective device to prevent a hazardous events arising, or to provide mitigation (to reduce the consequences of the hazardous event).

To meet functional-safety requirements, systems based on a single embedded processor (for example, those intended to be compliant with IEC 61508 or ISO 26262) require an appropriate and independent “watchdog” device which can monitor this processor.

This is essential because — even when systems are designed with great care — failures may still occur due to software errors (in your code or in the operating system you use), the impact of electromagnetic interference (EMI) or “single-event effects” (SEEs), or from various forms of hardware damage.

In some cases, your system may be subject to malicious attack (for example, Stuxnet-type virus attacks).

In many sectors, the impact of such system failures — whether caused by environmental factors, errors or deliberate attacks — can be serious injury or significant loss of life.

Our MoniTTor™ technology can help you to avoid such serious system failures.

Use of MoniTTor technology can simplify:

• The creation of secure embedded systems;
• The creation of high-integrity embedded systems which are compatible with international guidelines and certification standards.

MoniTTor technology

Two MoniTTor™ protection mechanisms are available (each with full design support):

• MoniTTor Wrappers (sometimes used with designs based on Linux or other standard operating systems);
• MoniTTor Agents (usually used with time-triggered designs).
