Audio DSP CPUs

10.12.6 Cortex-M33 Memory overview

Table 10 gives a more detailed memory map as seen by the Cortex-M33. The purpose of

the four address spaces for the shared RAMs is outlined at the beginning of this chapter.

The details of which shared RAM regions are on which AHB matrix slave ports can be

seen here. Further details given in Section 10.12.6.

[1] Gaps between AHB matrix slave ports are not shown.

[2] Details of this space may be found in Section 10.12.8 “APB peripherals”.

[3] Details of this space may be found in Section 10.12.9 “AHB peripherals”.
