dsp selection for LTE equipment
from the document, the TCI6618 and C6670 have the similiar function, including the coprocessors for LTE, e.g. FFT, Turbo/Viterbi decoder, CRC... etc.
These 2 chips are totally the same just name is different?
If I select the DSP type for LTE technology, 6670 is OK?
The two chips actually differ not too much.
But TCIxxxx is not public released and you should contact your local TI sales to apply for. So for a general-purpose application such as LTE, C6670 is better choice.
The major difference is the support model. TCI66x devices are not supported via the E2E forum, and instead are supported through local Field Applications Engineers, while the C66x devices are supported through the E2E Forum.
I would suggest talking to your local field applications engineer, if you don't know who that is, then please contact your local field sales representative to discuss this further.

Yes, it is okay to choose the TMS320C6670 for your LTE application. It is a powerful multi-core processor with several powerful communications-related co-processors included.

there's also a white paper discussing the C6670/TCI6618 usage in multistandard wireless base stations. Please see here.
