11 POWER MODE APPLICATION FOR SCENARIO
In this section, we describe how to apply system power mode for a specific operation scenario to consume as the
minimum power as possible, for easy understanding. We consider a several operation scenario: Audio playback,
Video playback, and Camcorder Recording.
Note that this is only an example for understanding, therefore you can apply system power mode in a different
way if you think it is better approach.
In this description, we mention the optimal configurations in NORMAL, IDLE, and DEEP-IDLE mode. You can also
use STOP, DEEP-STOP, and SLEEP mode if necessary.

Low-power MP3 playback application can be run according to the following sequence.
1. Loading MP3 file from NAND to input buffer in external DRAM.
2. Memory-copy data to input buffer
.
3. Cache line fill for MP3 code and data.
4. Read input stream from input buffer in DRAM.
5. MP3 decoding (Include parsing).
6. Write output data to output buffer in DRAM.
7. Memory-copy output data from output buffer in DRAM to output buffer in SRAM located in Audio sub-system.
8. Enter DEEP-IDLE mode.
9. Audio codec out through I2S0 (located in Audio sub-system).
10. Exit DEEP-IDLE mode by wakeup event from I2S0 output buffer empty.
11. If file buffer is empty, go to STEP 1.
12. Else if input buffer is empty, go to STEP2.
13. Else go to STEP 4.
In STEP 8, the following setting should be made before entering DEEP-IDLE mode.
1. I2S_FIFO_CLK_SEL field of LPMP3_MODE_SEL register in CLKCON @0xE020_0308 should be set to 1’b1.
2. OP_CLK field of IISMODE register in I2S0 @0x9E20_2004 should be set to one of 00, 01, and 10.
