Abstract
Systems and methods for improved security for a core in a portable computing device (PCD), such as a core operating a high level operating system (HLOS) are presented. In operation, a monitor module on the SoC is initialized. The monitor module sends a request to the core of the SoC and the monitor module receives a response from the core. A timer in communication with the monitor module is checked. The timer is reset or disabled by the monitor module if the response from the core is received at the monitor module before the expiration of the timer. Otherwise, the monitor module applies at least one security measure to the core as a result of the timer expiring.
