Shared memory issue

Lin Kuo-Wei

I use DM6446.  I have a question about shared memory. I read "TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide".

In this spec,"Support for non-aligned 32-bit (word) and 64-bit (double word) memory accesses" means

in DSP-side,can I only use 32-bit or 64-bit to access shared memory??

Can't I use 8-bit or 16-bit to access shared memory ??

Thanks every one
