Реферат: This document describes systems and techniques that enable independent clocking for configuration and status registers (CSRs). The described systems and techniques can provide a clock signal to a CSR set of an IP block with a derived clock rate an integer division slower than a clock rate of another clock signal that enables operation of the IP block, which may include communication between the IP block and an application processor. The derived clock rate is synchronous to but independent of the clock rate of the clock signal. In this way, the application processor and other entities can access the CSR set independent of clocking of the IP block. For example, the application processor can read from or write to the CSR set without waking the IP block from an Auto Clock Gated mode. By so doing, described aspects of independent clocking can reduce power dissipation associated with the CSR set.
