Abstract: A security command protocol provides secure authenticated access to an auxiliary security memory within a SCSI storage device. The auxiliary security memory acts as an authenticated separate secure storage area that stores sensitive data separately from the user data area of the SCSI storage device. The security command protocol is used to access the auxiliary security memory. The security command protocol allows a trusted execution environment to transport sensitive data to and from storage in the auxiliary security memory. The regular execution environment does not have access to the security command protocol or the auxiliary security memory. The security command protocol and auxiliary security memory eliminate the need for additional secure storage components in devices that provide the security features of firmware TPM.

Abstract: A debug controller monitors a tip-ring-ring-shield (TRRS) socket, within a form factor device, to detect whether a debug unit is transmitting a request for a TRRS socket debug connection. The form factor device also includes a system on chip (SoC), a switch, and an audio codec. The SoC includes the debug controller and a software debug interface. The switch couples a right audio lead and left audio lead of the TRRS socket to the audio codec. If the debug controller detects the request from the debug unit, then the debug controller instructs the switch to establish a TRRS socket debug connection. The switch establishes the TRRS socket debug connection by coupling right audio lead and left audio lead to the software debug interface instead of the audio codec. This establishment of the TRRS socket debug connection eliminates the need for manual configuration of the TRRS socket debug connection.

Abstract: Embodiments disclosed herein generally relate to the collection and correlation of power consumption data for mobile devices. Power consumption data for a mobile device is collected and correlated with system activity by monitoring what processes are being run on the CPU and measuring the power being consumed within the mobile device. The power being consumed within the mobile device is measured via a plurality of power monitors, such as sensors, disposed within the mobile device and buffered using an auxiliary microcontroller that resides separately from the CPU. Further, in some embodiments, temperature data also is measured via a temperature sensor.
