3.13.4.11 I/D Multiplexor
Master ports of the ICode and DCode of each ADSP are connected to a master port.
When the ICode and the DCode access the master port simultaneously, DCode has a higher priority than ICode.
3.13.4.12 Address Map
Figure APP-106 shows a map showing how to access resource of the APP_DSP via buses.
For external access of each ADSP, there are three AHP Lite master ports, which can be seen as the Application
Processor View. ICode bus is used for instruction fetch of the code memory region (0x00000000 - 0x1FFFFFFC),
DCode bus is used for data and the debug access of the code memory region (0x00000000 - 0x1FFFFFFF), and
System bus is used for instruction fetch, data, and the debug access of the address regions (0x20000000 -
0xDFFFFFFF and 0xE0100000 - 0xFFFFFFFF). Please note that 0x22000000 - 0x23FFFFFF region and
0x42000000 - 0x43FFFFFF region of the Application Processor View cannot be accessed.
The Application Processor View's three regions: 0x0000000 - 0x0FFFFFFF region, 0x2000000 - 0x2FFFFFFF
region, and 0x4000000 - 0x4FFFFFFF region are mapped in 0x0000000 - 0x0FFFFFFF region. Then, using
address converter, the 0x00000000 - 0x000FFFFF region can be remapped, being controlled by the program, as
the APP Window, GNSS Window, and SYS Window.
