Basics on 32-bit manipulation

Hi,

I am new to the Blackfin; however I'd like to use it for a comercial project (Audio). I am used to working with T.I.s 32-bit processors and reading that the B.F. has a "16/32 bit" description confuses me.

 

Questions (BF518) :

1)  SDRAM needs to be 16-bit, correct ?, if true, does that mean that the program word (instruction word size) is also 16-bit ? What tells the DSP that in order to execute an instruction that is in external memory, it would need to do one or two or multiple fetches ?

 

2) Does it make sense to use this DSP with a 24-bit / 96KHz CODEC ? or is the SHARC a better platform ?

 

3) Is there Cache in the DSP ?

 

Thanks. God bless,

 

Saul
