Abstract: A multi-phase boot operation of a virtualization manager at a virtualization host is initiated at an offload card. In a first phase of the boot, a security key stored in a tamper-resistant location of the offload card is used. In a second phase, firmware programs are measured using a security module, and a first version of a virtualization coordinator is instantiated at the offload card. The first version of the virtualization coordinator obtains a different version of the virtualization coordinator and launches the different version at the offload card. Other components of the virtualization manager (such as various hypervisor components that do not run at the offload card) are launched by the different version of the virtualization controller.

Abstract: In one example case, a cross-platform system includes a first automated test platform having a first test instrument and a first glue layer interface that exposes test functions to direct testing by the first test instrument. The system further includes a second automated test platform having a second test instrument and a second glue layer interface that exposes the same test functions to direct testing by the second test instrument. In the system, the glue layers abstract the respective and different control commands used by the different, first and second test instruments. Using the glue layers, the same higher-level test code can be executed by the control computers of both the first and second automated test platforms.

Abstract: An apparatus such as a system-on-a-chip includes memory that is distributed through multiple functional hardware circuits. Each functional hardware circuit includes memory, and each functional hardware circuit can be configured to have its memory used either by the respective functional hardware circuit or by the apparatus' master device (e.g., main processor). For those functional hardware circuits that are not needed for a given application, their memories can be repurposed for use by the master device. Related methods are also disclosed.

Abstract: In a system having a first clock domain with a first clock and a second clock domain with a second clock, the first and second clocks are monitored to determine whether one or both clocks are active. The first clock is selected to be an output clock if the first clock is active and the second clock is disabled irrespective of the clock selection signal. The second clock is selected to be the output clock if the second clock is active and the first clock is disabled irrespective of the clock selection signal. If both the first clock and the second clock are active, either the first clock or the second clock is selected according to a received clock selection signal.
