Abstract: A request for a high voltage mode is received and a high voltage timer is started in response to determining that a remaining amount of high voltage credits exceeds a voltage switch threshold value. A switch to the high voltage mode is made in response to the request. A low voltage mode is switched to in response to an indication. The request may be received from an application running on a data processing system. If the indication is that the high voltage timer has expired, a low voltage timer is started in response to switching to low voltage mode. If the high voltage request is still active when the low voltage timer expires, a switch back to high voltage mode occurs and a new high voltage timer is started.

Abstract: A method and apparatus for securely booting software components in an electronic device to establish an operating environment are described herein. According to an aspect of the invention, software components are to be executed in sequence in order to establish an operating environment of a device. For each software component, a security code is executed to authenticate and verify an executable code image associated with each software component using one or more keys embedded within a secure ROM (read-only memory) of the device and one or more hardware configuration settings of the device. The security code for each software component includes a common functionality to authenticate and verify the executable code image associated with each software component. In response to successfully authenticating and verifying the executable code image, the executable code image is then executed in a main memory of the device to launch the associated software component.

Abstract: A process and apparatus for configuring one or more integrated circuits within a device in a manufacturing process is described. In an exemplary process, a device is manufactured by assembling a chip onto a board such as a printed circuit substrate and the chip is fused from power routed across the board to the chip. The power source for the fusing can be generated from the internal power supply on the board or received on a test point on the board itself or a connection interface (e.g. a USB interface) coupled to the board. In an exemplary apparatus, a device comprises a chip with a plurality of fuses that are used to configure the device and a board coupled to the chip, with the board capable of routing power from the board to the chip and the power is used to blow one or more of the plurality of fuses.

Abstract: A method and apparatus for personalizing a software component to be executed in particular environment are described herein. According to an aspect of the invention, in response to an executable code image representing a software component to be installed in an electronic device, the executable code image is encrypted using an encryption key. The encryption key is then wrapped with a UID that uniquely identifies the electronic device, where the UID is embedded within a secure ROM of the electronic device. The wrapped encryption key and the encrypted executable code image are then encapsulated into a data object to be stored in a storage of the electronic device, such that when the electronic device is subsequently initialized for operation, the executable code image can only be recovered using the UID of the electronic device to retrieve a decryption key in order to decrypt the executable code image.

Abstract: Data processing systems with interrupts and methods for operating such data processing systems and machine readable media for causing such methods and containing executable program instructions. In one embodiment, an exemplary data processing system includes a processing system, an interrupt controller coupled to the processing system and a timer circuit which is coupled to the interrupt controller. The interrupt controller is configured to provide a first interrupt signal and a second interrupt signal to the processing system. The processing system is configured to maintain a data structure (such as, e.g., a list) of time-related events for a plurality of processes, and the processing system is configured to cause the entry of a value, representing a period of time, into the timer circuit. The timer circuit is configured to cause an assertion of the first interrupt signal in response to an expiration of the time period.

Abstract: A method and an apparatus for configuring a key stored within a secure storage area (e.g., ROM) of a device including one of enabling and disabling the key according to a predetermined condition to execute a code image are described. The key may uniquely identify the device. The code image may be loaded from a provider satisfying a predetermined condition to set up at least one component of an operating environment of the device. Verification of the code image may be optional according to the configuration of the key. Secure execution of an unverified code image may be based on a configuration that disables the key.
