Input/output data rate synchronization using first in first out data buffers

An input/output data rate synchronization system comprising:

• a first data buffer that receives input data at a first rate, that temporarily stores said input data, and that outputs said input data at a second rate;
• a data processing module that receives said input data from said first data buffer at said second rate and that outputs processed data at a third rate that is different than said second data rate;
• and
• a second data buffer that receives said processed data from said data processing module at said third rate, that temporarily stores said processed data, and that outputs said processed data at a fourth rate that is different than said third data rate,
• wherein said data processing module temporarily stops receiving said input data and generating said processed data when said second data buffer exceeds a first predetermined capacity,
• wherein said data processing module increases said second rate when said first data buffer exceeds a second predetermined capacity,
• wherein said first data buffer includes a read pointer and a write pointer and wherein said data processing module determines an amount of said input data in said first data buffer with respect to said second predetermined capacity by computing a difference between positions of said read and write pointers, and
• wherein said second rate is based on a rate of change of said difference between positions of said read and write pointers.
