Monitoring and compensating for real time local circuit speed in an integrated circuit |
摘要 |
An integrated circuit comprises an oscillator that generates an oscillator signal. A first counter generates a first count based on transitions of the oscillator signal. A first circuit generates a match signal based on the first count and a reference count. A second counter generates a second count that is initialized at a starting count and adjusts the second count based on transitions of a reference clock signal. An output circuit outputs an oscillator speed based on the second count and the match signal. The oscillator speed is defined by a range that is independent of a frequency of the reference clock signal.
