Abstract: Techniques for enabling a rapid clock frequency transition are described. An example of a computing device includes a Central Processing Unit (CPU) that includes a core and noncore components. The computing device also includes a dual mode FIFO that processes data transactions between the core and noncore components. The computing device also includes a frequency control unit that can instruct the core to transition to a new clock frequency. During the transition to the new clock frequency, the dual mode FIFO continues to process data transactions between the core and noncore components.
