ABSTRACT:
An input/output data rate synchronization system includes a first data buffer that receives input data at a first rate, that temporarily stores the input data, and that outputs the input data at a second rate. A data processing module receives the input data from the first data buffer and outputs processed data at a third rate. A second data buffer receives the processed data from the data processing module at the third rate, temporarily stores the processed data, and outputs the processed data at a fourth rate. The data processing module temporarily stops receiving the input data and generating the processed data when the second data buffer exceeds a first predetermined capacity. The data processing module increases the second rate when the first data buffer exceeds a second predetermined capacity and decreases the second rate when a difference between the second and first rates is greater than a predetermined rate.
