1843 L3 memory
Can DSS use 2MB of L3 memory?
What shall I do?
A maximum of 768KB of ECC-enabled memory is available as shared DSS_L3 memory in the DSP
subsystem. The memory is structured into sections of 128KB, out of which can be allocated to the DSP or
master Cortex-R4F, as shown in Figure 10-2.
On-chip L3 shared memory of 1024KB, with 512KB dedicated to DSP and 512 KB of memory shared
between the DSP and master subsystems.
