Most high-speed data converters cannot be connected directly to a digital signal processor (DSP). The required transfer rates would tie up most of the DSP's I/O bandwidth. A FIFO is an appropriate solution for this problem because it can buffer a large block of data, and the DSP can read data from the FIFO in a burst mode. This is much more efficient compared to single reads for every sampled valu
