Abstract: One or more examples relate to generation of quality indications for a randomly generated number or a random number generator more generally. An example apparatus may include a memory and a logic circuit. Such a memory is to receive and store a previous randomly generated number and a current randomly generated number. Such a logic circuit is to: determine a relationship between the previous randomly generated number and the current randomly generated number; and generate an indication of quality of the current randomly generated number at least partially responsive to the determined relationship between the previous randomly generated number and the current randomly generated number.

Abstract: A microcontroller has integrated monitoring capabilities for network applications. The disclosed techniques can take advantage, for example, of an unused, duplicate network controller that is present in some microcontrollers by providing selection circuitry and configuration capabilities that allow the unused, duplicate network controller to be used for the purpose of monitoring frames that are transferred between network media and another network controller residing on the microcontroller. The monitored frames can then be used, for example, for debugging or other purposes, such as statistical analyzes or security enhancements.
