DSP various version specification, requirement, feature?

[Finite]

Hello, I'm Looking for infomation related to DSP. I try google and yahoo...no luck. Any of you can fill me in about DSP?

There is general information available fro the Ti website, not sure I have never seen anything useful on the Infineon one, it appears such information is confidential and only released to the modem manufacturers. There have been a few leaked documents with a bit more info, but nothing new for several years, have a search for "ar7_dsp72_feature_control", for example.

Very good question! For my part, I think they are missing a trick here, by not releasing the source code to all their drivers. After all, if we fix or improve the code so that the platform is better supported, they are only going to sell more hardware as a result. It seems that such plain logic is very often lost on some companies.

I'm sure Ti/Infineon do give THEIR customers the detailed docs/release notes under an NDA. Their customers are the big router manufacturers Aztech, Linksys, Netgear, D-Link etc, whose only interest in firmware is providing bug fixes under warranty period - they would much rather new features were just built into new routers!

The dsp driver is a binary for the embedded dsp that does the adsl filtering/decoding, the atm driver is a Linux kernel module the source for this is needed for the likes of OpenWRT to build it into a recent Linux kernel - they have ATM 7.03 source-code.
