What next with this audio codec project? Thank you!!!

[peacherwu]

We are working on an audio codec project with very limited experiences. So far we have implemented the algo in Matlab and ported it as a vs 2005 float-point version. We need to figure out what to do next.

All we know is a fixed-point chip would be adequate for our purpose.

We are planning to
1) convert the float-point into fixed-point C; THEN
2) estimate the computation complexity and storage need; THEN
3) choose the right chip (probably from TI)
4) we don't know

The questions are:
a) Does this make sense?

b) We are not sure what tools are available for step 2, i.e. estimating the complexity mostly?

c) After we are done selecting chip, what should we do? Contact TI for samples and development kit, and then port the c code?

Thank you in adv for any advice!!!

Hi peacherwu,
The step 2 deepends on what kind of codec you want to implement, encoder or decoder, and what kind of algorithm you use, how many mutiplicer or adder, how you can optimze your algorithm, what is your implement structure and how you can optimize your algorithm, do you need implement as realtime, etc, ...
In genearal, it is hard to say because it depends.
There is no availably estamation tools you can expect.
