2.4.5 Memory Allocation

Note:

The BSD demo memory usage can always be found in the MAP file.

Two memory heaps are created, one in the local core memory, and the other in shared L3 memory, occupying 256KB shared memory of APPSS and 160KB shared memory of HWASS. The usage of the shared memory depends on the configuration. At the start time, after the CLI commands have been received and configuration completed, memory usage of these two heaps is printed out on the console. A buffer is allocated from the local core memory for the group tracker algorithm.

The memory heap usage for the CLI configuration file profile_120m_40mpsec_bsdevm_16tracks.cfg which is provided in this SDK release is shown in Table 2-5.
