Section 29 AESOP
Section 29 AESOP
The audio encoding special option (AESOP) is an accelerator for AAC audio encoding. The
AESOP is independent hardware that relieves the CPU of the load of AAC audio encoding. In
operation at 66 MHz, it can perform AAC audio encoding at up to 20-times the normal speed.
AAC encoder processing can be executed by the AESOP module.
