ABSTRACT:
A system includes a first buffer configured to receive data at a first rate, and output the data at a second rate. A processing module configured to receive the data from the first buffer at the second rate, convert the data into processed data, and output the processed data at a third rate. A second buffer is configured to receive the processed data from the processing module at the third rate, and output the processed data at a fourth rate. The third rate is faster than the fourth rate to avoid a buffer underflow condition in the second buffer. In response to the second buffer reaching a predetermined capacity, the processing module is further configured to enter into a break state in which the processing module temporarily stops both receiving data from the first buffer and outputting the processed data and adjusts the second rate to avoid a buffer overrun condition in the first buffer.
