Can use CCS v4.1 MQT_1_21 EVM6474 project to the EVM6472 ?

Hi,

Recently, I use the MQT in the EVMC6472 to achieve communication between multi-core, I see this site "http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/35543/123998.aspx"  

which i known the example of "1205.mqt_1_21.tar.gz" may use in the EVM6474 ,so i would like to ask whether this example can use in the EVM6472, if not , what need to modify in the process of migration ? By the way, what are the ways to achieve Inter-process communication in the EVM6472 ?

I appreciate any help you may offer!

Thanks!

    Hi,

    Although MQT uses extensively the MSGQ component of DSP/BIOS, its configurations are heavily dependend on the device. Therefore I will move your question to the C6000 Multicore DSPs so you can get more educated answers there.

    Regards,

    Rafael

    thanks !

    In the paper "Shared Memory Message Queue Transport (MQT) and Pool Modules for C647x"4834.sprab09.pdf,This document and the example application focus on C647x devices, specifically the
    C6474 device (three cores),it pointed out that

    "The SMMQT and SMPOOL modules can be ported to other C6000 chips. The following are
    some of the areas that must be modified to port the modules:
    • Create a different critical region implementation.
    • Modify the cache line sizes as described in Section 17.
    • Manage the resets appropriately in SMPOOL and SMMQT.
    • Issue the appropriate interrupts in the SMMQT. "

    But i don't know what is that mean?

    Thanks!
