SECURITY AND SAFETY MANAGER IMPLEMENTATION IN A MULTI-CORE PROCESSOR
First Claim
1. A system comprising:
- a multi-core computer processor;
wherein one or more cores of the multi-core computer processor are configured as a security co-processor for the system and for other cores of the multi-core processor;
wherein an operating system of the security co-processor is independent of operating systems of the other cores of the multi-core processor; and
wherein the security co-processor is configured to boot before the other cores and to enforce security policy on the other cores.

Abstract
A system includes a multi-core computer processor. One or more cores of the multi-core computer processor are configured as a security co-processor for the system and for other cores of the multi-core processor, and one or more cores of the multi-core computer processor are configured as a safety manager co-processor for the system and for other cores of the multi-core processor. An operating system of the security co-processor and an operating system of the safety manager co-processor are independent of operating systems of the other cores of the multi-core processor. The security co-processor and the safety manager co-processor are configured to boot before the other cores and to enforce security policy and/or safety policy on the other cores.
