Abstract: A digital glitch filter for filtering glitches in an input signal includes a first flip-flop for generating a filtered output signal, and a self-oscillating circuit for generating a self-oscillating clock signal. A first logic gate enables the self-oscillating circuit when the filtered output signal is not equal to the input signal. A ripple counter generates a divided clock signal by dividing the self-oscillating clock signal. A counter and comparator counts the divided clock signal to obtain a count number and compares the count number with a predetermined count target. A second flip-flop, which is connected to the counter and comparator, generates a valid signal, which is activate when the count number reaches the count target. The valid signal is input to the first flip-flop such that the filtered output signal toggles when the valid signal is active.

Abstract: A System on a Chip (SoC) has a first set of switches, each having first terminals for routing SoC signals and a second terminal, and a second set of switches. Each switch of the second set of switches has third terminals for routing signals with the first set of switches, and a fourth terminal. A SoC control module defines a switching configuration, and includes a first memory portion for storing a first switching protocol for the first set of switches. This defines, for a switch of the first set of switches, an electrical path between one of the first terminals and the second terminal. A second memory portion stores a second switching protocol for the second set of switches, and defines, for a switch of the second set of switches, an electrical path between one of the third terminals and the fourth terminal.
