MELPe on 16-bit DSPs

Started by ahmadagha23 April 21, 2008
Hi;
As you know MELPe receive 16-bit inputs and the processing includes
some 8-bit operations. My question is that: "Would you know if a 16-bit
addressable DSP,like c55x, is used to implement MELPe how much (in
percent) of memory may be unused?"

"In the above case is there any way to use dissipated memory without
MIPs increasing?"

I saw the price of 1MW 10ns asynchronous RAM from ISSI is 17.3$ while
the 0.5MW with the same conditions is 3$. Is it true? Do you know any
else?

here is an example of implementationon C30, C55 is much more efficient...
