/**
|
|
* Usage:
|
|
* 1. Enable SCO_CP_ACCEL ?= 1 to enable dual core in sco
|
|
* 2. Enable SCO_TRACE_CP_ACCEL ?= 1 to see debug log.
|
|
* 3. Change channel number if the algo(run in cp) input is more than one channel: sco_cp_init(speech_tx_frame_len, 1);
|
|
* 4. The code between SCO_CP_ACCEL_ALGO_START(); and SCO_CP_ACCEL_ALGO_END(); will run in CP core.
|
|
* 5. These algorithms will work in AP. Need to move this algorithms from overlay to fast ram.
|
|
*
|
|
* NOTE:
|
|
* 1. spx fft and hw fft will share buffer, so just one core can use these fft.
|
|
* 2. audio_dump_add_channel_data function can not work correctly in CP core, because
|
|
* audio_dump_add_channel_data is possible called after audio_dump_run();
|
|
* 3. AP and CP just can use 85%
|
|
*
|
|
*
|
|
*
|
|
* TODO:
|
|
* 1. FFT, RAM, CODE overlay
