Computer device(s), apparatus(es), and methods enable and/or perform interface independent test boot of a System on Chip (SoC). A test Direct Memory Access hardware unit (test DMA) and an Automatic Test Equipment (ATE) hardware unit suspend a processor core of the SoC, download a test case, perform a seamless switch into functional mode of the SoC, and execute the downloaded test case. The test DMA may mediate between the ATE and internal memory in the SoC.

Interface independent test boot method and apparatus using automatic test equipment

A processor includes logic to generate a wakeup code value for a deep sleep state in which the processor is powered down, store the wakeup code value to a first location in a power domain in which power is maintained in the deep sleep state, store the wakeup code value to a second location in a non-volatile memory device, and initiate entry into the deep sleep state. The processor also includes logic to begin execution of a wakeup sequence upon waking up from the deep sleep state. The wakeup sequence includes a determination of whether a value read from the second location and a value read from the first location match. If they do not match, the processor triggers an exception handling sequence, which may include a secure boot sequence. If they match, the processor continues executing the wakeup sequence without executing a secure boot sequence.

Security mechanisms for extreme deep sleep state

A radio communication device and a method for booting a radio communication device are provided. The radio communication device can be configured to load an operating system code of a processor during execution of an authentication procedure code. For example, a first portion of the operating system code can be loaded, then the authentication procedure code can be loaded after the loading of the first portion of the operating system code. After the initiation of an authentication procedure that is based on the authentication procedure code, then a second portion of the operating system code can be loaded.

Radio communication device and method for booting a radio communication device

In various embodiments of the invention, a radio communication device and a method for booting a radio communication device are provided. In an embodiment of the invention, an operating system code of a processor is loaded during execution of an authentication procedure code.

For example, a circuit arrangement is provided comprising a clock generator configured to generate a clock signal, a circuit having a low power mode, and a controller, configured to receive, when the circuit is in the low power mode, a request specifying that the circuit should return from the low power mode and trigger the circuit to return from the low power mode when the number of clock cycles of the clock signal since the reception of the request has reached a threshold value.
