Related to Board Support Packages (BSP) for embedded systems, mark the incorrect statement. A Board Support Package (BSP) provides a standardized interface between the hardware and the operating system. Having Board Support Packages (BSP) allows the aplication SW to be ported to different architectures. Board Support Package (BSP) provides a standarized interface between the hardware and the operating system.

What is the leading paradigm of federated architectures. Limit weight of systems. Maximize Fault-tolerance. One function, one system. Partitioned systems are mandatory.

Mark disadvantages of federated architectures: Not fault-tolerant. Problems with spare parts logistic. Increased power consumption. Each box has a specific function, with specifically development hardware and software. Data is not shared among various systems. Significant maintenance costs. Increased weight and power consumption. Difficult to implement.

Mark advantages of integrated architectures: Not fault-tolerant. Sensor data shhttps://static.daypo.com/images/document.pngared among several systems. Reduced weight and power consumption. Easy maintenance.

The DO-254 hardware design processes generate the design data and resultant hardware item. These processes are: Validation, verification, configuration management, process assurance and certification liaison. Requirements capture, conceptual design, detailed design, implementation and production transition.

The DO-254 hardware supporting processes generate the design data and resultant hardware item. These processes are: Requirements capture, conceptual design, detailed design, implementation and production transition. Validation, verification, configuration managment, process assurance and certification liaison.

Tick the right statements: Possible. The planning and supporting processes run sequentially and the development process is continued throughout the project. The planning and supporting processes run in parallel and the development process is continued throughout the project. The supporting and development processes run sequentially and the process is continued throughout the project. The planning and development processes run sequentially and the supporting process is continued throughout the roject.

A Derived Requirement is an Additional requirement resulting from the hardware design processes, which may not be directly traceable to higher level requirements. Select the options that refer to derived requirements: At each phase of the development activity, decisions made as to how particular requirements or groups of requirements are to be met. The consequences of these design choices become requirements for the next phase of development. Low Level Requirements.

The conceptual design process produces a high-level design concept that may be assessed to determine the potential for the resulting design implementation to meet the requirements. This may be accomplished using such items as, select all that apply: Functional block diagrams. Design and architecture descriptions. Circuit card assembly outlines. Chassis sketches.

DO-254 Validation and Verification. Tick the right statements: The verification process provides assurance that the hardware item requirements are correct and complete with respect to system requirements allocated to the hardware item. The validation process provides assurance that the hardware item implementation meets the requirements. Validation provides assurance that the requirements are correct and complete. Verification provides assurance that the implementation meets the requirements.
