the possibility of porte LLVM to the special architecture ?

I'n now finding a good compiler infrastructure for our DSP processor
the target DSP architecture that we plan to port have two special character :
1. SIMD instruction is the key of performance
  >the SIMD instruction format is simple as
      mulit register = mulit register opcode multi-register
        destination src_1 src_2
   > the register of destination and source is general register
   > SIMD load /store have no special memory alignment requirement;
2. memory access character that load/store can only access 32bits
memory space each time; In the target architecture, the " char",
"short" , "int" , "float" and "long long" are all 32bits ( 4bytes) .

If you are familiar with TigerSharc 201 DSP , you can simple consider
our architecture just as TS201.

Do you think it is easy and possible to port the LLVM to such odd
architecture .

any comment about the probelm that we use LLVM as infrastructure for
the target DSP is appreciated.
Thanks !
