29.4.2 AESOP Processing Procedure
Figure 29.4 shows a sample flowchart of the processing procedure.
AESOP processing procedure
Activate AESOP
Set initial values for encoding
Set data transfer mode
Initiate encoding
DMA transfer: Requests PCM data input (1024 times), frame data (1)
DMA transfer: Requests PCM data input (1024 times), from frame data (2)
Processing AESOP encoding
→ Repeated for the number of frames to be transferred
DMA transfer: Requests AAC data output (1024 times)
(generated when 4 kbytes of data are stored)
Process the processing status end interrupt
(1)
(2)
Change initial values for encoding → (1); End encoding processing → Halt AESOP; Next tune → (2)
Halt AESOP
End
