SIMD from external memory (ADSP-21161N)

Hi all,

 

Id like to run a FFT optimised for SIMD on a large amount of data in external SDRAM. I am using the ADSP-21161N processor and the reason why I am asking if its possible is because Ive read in both the compiler manual and the run time library manual that it is not possible but it is stated that its not possible for an en external bus width of 32 bits, My memory is setup to run in 48 bit mode, will SIMD still be a problem or will the wider bus width support the SIMD function? Thanks in advance!

 

Allan
