Abstract: Techniques and apparatuses are described that implement a signal fingerprint. In an example aspect, a fingerprint module can monitor signals distributed between a host board and peripherals during an operation performed by the host board. The fingerprint module can generate a signal fingerprint that represents characteristics of the signals that correspond to the operation. With the signal fingerprint, the fingerprint module can improve user experience by protecting the electronic device from anomalous behavior. The fingerprint module can also use the signal fingerprint to improve the user experience and improve system performance through appropriate electronic device component selection. The disclosed techniques and systems can therefore provide electronic device operation reliability, protect sensitive data, and improve electronic device performance while reducing costs and time associated with the design and testing phases of such devices.

Abstract: Techniques and apparatuses are described that implement software-defined hardware. In example aspects, a hardware manager can enable and disable different combinations of peripherals coupled to a host device. Software can be executed on different enabled combinations of peripherals to determine which combinations best meet the requirements of a product. Combinations of peripherals can be updated with alternative or new peripherals that have new features or replace obsolete peripherals. Thus, the hardware manager can provide a modular validation platform that allows a manufacturer of electronic devices to skip a prototype phase, qualify new peripherals as replacements for existing peripherals that may become obsolete, and iterate between different combinations of peripherals to determine ideal combinations. The disclosed techniques and systems can therefore reduce resources, time, and costs associated with design and testing phases of electronic devices.
