60 * buffer to the DSP fifo to decoding/encoding, once IRAM buffer is empty by
62 * DDR buffer to IRAM buffer.
64 * Since the DSP fifo is only 512B, IRAM buffer is allocated by 32K, and DDR
65 * buffer is larger to 2M. That means only the IRAM 32k data is transferred
66 * done, we can wake up the AP system to transfer data from DDR to IRAM, and
