audio core

here is my code by C

while(1)

{

//wait for interrupt signal

ctrl_reg = IORD_ALT_UP_AUDIO_CONTROL(ALT_UP_AUDIO_BASE);

ctrl_reg &= ALT_UP_AUDIO_CONTROL_RI_MSK;

if(ctrl_reg == 0) continue; //if there isn't read interrupt signal , continue wait

ctrl_reg = IORD_ALT_UP_AUDIO_CONTROL(ALT_UP_AUDIO_BASE);

//clear interrupt flag

ctrl_reg &= ~ALT_UP_AUDIO_CONTROL_RI_MSK;

IOWR_ALT_UP_AUDIO_CONTROL(ALT_UP_AUDIO_BASE, ctrl_reg);

//read left channel

alt_up_audio_read_left_channel(&left_reg,read_length);

//read right channel

alt_up_audio_read_right_channel(&right_reg,read_length);

// write left channel

alt_up_audio_write_left_channel(&left_reg,write_length);

// write right channel

alt_up_audio_write_right_channel(&right_reg,write_length);

}
