The SoCĬommunicates with the VMCU through USB, UART, SPI, and GPIO signals. Vehicle Master Control Unit (VMCU) The microcontroller that provides the interface between the vehicle network and the SoC. Vehicle Interface Processor (VIP) See Vehicle MCU. The VHAL abstracts this vehicle network to enable AAOS to interact with The vehicle network can use any physical layer (such as CAN,
NVIDIA POWER MANAGEMENT MODED ANDROID
Vehicle HAL (VHAL) The Android API used to interface with the vehicle network. The SoC is placed into S3 power modeĪnd the CPU is powered off while RAM remains powered on. Suspend Also referred to as Suspend-to-RAM (S2R or STR). Nvidia, Qualcomm, Renesas, and Texas Instruments. System-on-a-Chip (SoC) Main processor that runs AAOS, typically supplied by manufacturers such as Intel, MediaTek, Power Management Integrated Circuit (PMIC) Chip used to manage power requirements for the host system. Media Processor (MP) See System-on-a-Chip (SoC) below. (hibernate) and RAM content is written to non-volatile media (such as flash or disk) and the entire Hibernate Also referred to as Suspend-to-Disk (S2D/S4). Hardware Abstraction Layer (HAL) A software layer that all other higher level modules must interact with in order to access General Purpose Input or Output (GPIO) A digital signal pin for general purpose use. CarPowerPolicyDaemon (CPPD) Exposes the AIDL interfaces for native processes to register power policy listener. CarPowerManagementService (CPMS) Implements the car power state machine, interfaces with VHAL, and performs the final calls to CarPowerManager (CPM) Exposes an API for apps to register for power state changes. Integrated with the embedded operating system. That allow an embedded operating system to function in a given hardware environment (a motherboard),

Board Support Package (BSP) The layer of software that contains hardware-specific boot firmware and device drivers These terms are used throughout this document: Application Processor (AP) Part of the System-on-a-Chip (SoC). Integrators areĪlso responsible for disabling wake sources and ensuring that shutdowns are not postponed
With the Vehicle Hardware Abstraction Layer (VHAL) and the kernel implementation. Integrators are responsible for integrating The VMCU, integrators must implement several components. State transitions are triggered by the Vehicle Master Control Unit (VMCU). To support vehicle-specific power management, Android provides a
