AWR1642BOOST: Ram Size of AWR1642Boost

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

What is the total Ram size of AWR1642Boost board?

Regards

  • It has total of 1.5MB memory which is distributed between MSS & DSS cores.

    Prog RAM (256kB*)
    Data RAM (192kB*)
    L3 Shared (768KB)
    L2 Memory(256KB)
    L1 data (32KB)
    L1 code (32KB)

    L3 shared memory can be assigned between the Cortex R4F of the master subsystem and the DSP core.

    Please refer AWR1642 TRM document for more detail

  • Depending upon the memory requirements of a certain application, can all of this 1.5MB memory be used?
  • Memory is distributed between MSS and DSS, as I mentioned in above post program and data RAM is fixed with MSS core (256KB and 192KB).
    DSS gets 768KB (L2 and L1 memory on top of this).

    Adding to that, if application requires more memory then I would suggest to move some of functionality to MSS and put functionalities to DSS which are highly depended on DSP processing. As an example FFT processing can be done on DSS and further tracking algo can be run on MSS core, where result of FFT is communicated to MSS over HSRAM and/or Mailbox memory.


    Please refer SDK application infrastructure for more info about inter core data transfer.
