Abstract
Methods and apparatus relating to provision of core tightly coupled lockstep for high functional safety are described. In an embodiment, a master core, coupled to a slave core, executes one or more operations to support Advanced Driver Assistance Systems (ADA) or autonomous driving. The master core and the slave core receive the same input signal and core tightly couple logic causes generation of a signal in response to comparison of a first output from the master core and a second output from the slave core. The generated signal causes an interruption of the one or more operations in response to a mismatch between the first output and the second output. Other embodiments are also disclosed and claimed.
