INTEGRATED CIRCUIT COMPRISING CIRCUITRY TO CHANGE A CLOCK SIGNAL FREQUENCY WHILE A DATA SIGNAL IS VALID

摘要

Methods and apparatuses for communicating information are described. In some embodiments, a first integrated circuit (IC) provides a clock signal and a data signal to a second IC, wherein the data bits of the data signal are timed according to the clock signal, and wherein the frequency of the clock signal is capable of being changed even when the data signal is valid.

主权项

1. An integrated circuit (IC), comprising:
a first node to output a clock signal having a clock signal frequency; a second node to output a data signal, wherein bits in the data signal are timed according to the clock signal; and circuitry to modify the clock signal frequency from a first frequency value to a second frequency value while the data signal is valid.
