Can I place the System MMU (SMMU-400) before the DRAM Memory Controller (DMC-400)?

Hi all,

 

I have two A15 CPUs and 1GByte of DRAM memory. I want to dedicate 0.5GByte of memory to each CPU. Would the following system work?

 

(A15)  (A15)

    SMMU

     DMC

 

The SMMU will map the addresses coming from the first A15 (0-0.5GB) to the first half portion of the DRAM memory (0-0.5GB) and the addresses coming from the second A15 (0-0.5GB) to the second half of the DRAM memory (0.5GB-1GB). Moreover, the SMMU will provide protection allowing each CPU to access only its portion of memory.
