Memory Mapping
Overview of Memory Map Configuration
Memory map is made up of three types of views. The “SYS View” can be referred from System and I/O Processor,
the “GNSS View” can be referred from the GNSS DSP, and the “APP View” can be referred from Application
Processor. The SYS Window, the GNSS Window, and the APP Window are defined so that each of them can be
accessed to the same address from its own processor.
The SYS Window defines addresses of the master device and the slave device inside the SYSIOP and the SCU.
The GNSS Window defines addresses of the master device and the slave device inside the GNSS, the APP
Window, inside the APP, as well.
Figure Memory Mapping-2 shows memory map configuration.
