L2 SRAM memory mapping of C66x DSPs in TCI6638K2K

Ranjit Kumar19

Looking at the memory map of K2K these are the following locations for L2 SRAM

00 0080 0000 00 008F FFFF 1M Reserved L2 SRAM L2 SRAM

00 1080 0000 00 108F FFFF 1M CorePac0 L2 SRAM CorePac0 L2 SRAM CorePac0 L2 SRAM

00 1180 0000 00 118F FFFF 1M CorePac1 L2 SRAM CorePac1 L2 SRAM CorePac1 L2 SRAM

and so on.

My question is what it the significance of first one (ie 00 0080 0000 00 008F FFFF ) .Which DSP it is talking about.

It is not CorePac0 as CorePac0 is 00 1080 0000 00 108F FFFF

    00 0080 0000 to 00 008F FFFF - This is a local address space of L2 SRAM. The each core pac of DSP can access the its own L2 SRAM in this address space. There is no access to this address by ARM.
    00 1x80 0000 to 00 1x8F FFFF - This is a global address of L2 SRAM. The ARM and DSP cores can access the L2 SRAM of other core pacs in this address space.

    I hope it clarifies your question.
