The OMAP-L138 Applications Processor contains two primary CPU cores: an ARM RISC CPU for general-purpose processing and systems control; and a powerful DSP to efficiently handle communication and audio processing tasks. The OMAP-L138 Applications Processor consists of the following primary components:
• ARM subsystem and associated memories
• DSP subsystem and associated memories
• A set of I/O peripherals
• A powerful DMA subsystem and SDRAM EMIF interface
