Abstract
A method for hardware-based periodic self-testing of safety mechanisms includes generating a test pattern after data processing has initiated in at least one block of a processor. The test pattern is provided to a safety mechanism. The safety mechanism generates a syndrome based on the test pattern. A fault in the safety mechanism is determined based on the syndrome.
Claims20
An apparatus, comprising:
- at least one memory;
- a safety mechanism for at least one block of a processor;
- and
- logic for testing the safety mechanism, the logic being configured to:
- generate a test pattern after data processing has initiated in the at least one block of the processor;
- provide the test pattern to the safety mechanism, the safety mechanism generating a syndrome based on the test pattern;
- and
- determine a fault in the safety mechanism based on the syndrome.
