TMS320F28379D: RAM memory map

Part Number: TMS320F28379D

Hi TI team,

While doing the cmd file for an application, I needed more RAM.

While doing the memory calculation, I found that I have only 168KB of RAM, instead of the 204KB.

So I'm missing ~40KB of RAM.

Here's the calculation in excel. I used table 9-1 from the datasheet.

Can you please help me understand what I'm missing?

Thanks!

    Hello Ari,

    Referencing table 6-1 in the same datasheet, it seems that you may have left out the fact that the dedicated and local shared RAM are per CPU. This would be M0-1, LS0-5, and D0-1 (36 KB) per each CPU, so if you add another 36 KB you should have 204 KB total.

    Best regards,

    Omer Amir

    Yes you're correct.

    Thanks for clarifying this.
