What is the difference between c5510 and vc5510?

[ahmadagha23]

Dear friends,
I want to implement the MELPe vocoder and another control algorithm as telephony board. As you know MELPe needs large data memory. I decided to use c5510 or c6204 due to their low cost and their unified data and memory address spaice.(not limited data memory space isn't it?).
Now in your idia which of these two DSPs are proper?

What is the difference between c5510 and vc5510?

Re: DSP selection

Hello,

be sure not to violate any copyright: MELP and MELPe are covered by several patents and it is not very clear who is the owner of what.
I suggest you to contact sales representatives of TI or their third party provider which sold MELP/MELPe packets for C5000 or C6000 platform.
In general TI is not interested in selling the license of vocoders (it is a chip manufacturer) and lets you use the 2400 bps Vocoder for free if implemented on its DSP, but the situation seems not so clear for the MELPe (1200 and 600 bps) whose copyright is claimed by more than one company, so be very careful about this point if you are thinking to a commercial application.
