66AK2H12: XMC MPAX setting

Part Number: 66AK2H12

Hi Champs,

We  need use inside of C66 core XMC Mpax address extension function on the ARM core.

because, we would like to set C66 core program to difference memory space between physical and logic address.

physical : 0x0_B800_0000

logic     :  0x6000_0000

However, according to this Table 8-1, it is not allow to from ARM  to the XMC register.

We need set XMC-MPAX physical/logic exchange before executing C66x core program.

Do you have any idea ?

  • Hi,

    The XMC is a memory controller within the C66x CorePac, it is not accessible from ARM.
    If you want to do address extension from ARM you could use the MSMC MPAX, which is a chip level memory controller, not dedicated to a specific CorePac.

    Best Regards,
