摘要：
A dynamic clock frequency module includes a request evaluation module configured to generate a sum of requests to utilize a system bus from a plurality of modules. A frequency assignment module is configured to calculate a clock frequency for the system bus in response to the requests and adjust the clock frequency between at least two non-zero frequency values. A pulse stretch module is configured to increase a period of time that at least one of the requests is asserted in response to the sum.
