ADSP-2126x Memory Map
The ADSP-2126x family is composed of a variety of models that have
varying amounts of RAM and/or ROM memory. However, in general,
there are two memory spaces: internal memory space and external (DMA)
memory space. These spaces have these definitions:
• Internal memory space. This space ranges from address 0x00 0000
through 0x1F FFFF. Internal memory space refers to the DSP's
on-chip RAM, on-chip ROM, and memory-mapped registers.
• External (DMA) memory. For information on external DMA
memory space please refer to the product-specific data sheet.
