Who know Ti-5220 lpc algorithm?

Dear friends:

I have a source code which is LPC decoder for TI-5220 algorightm, I
only have the souce code, but hasn't any document about it, Can you give me
some imformation about this algorithm?
Thank you very much!

Linear Predictive Coding decoder for TI-5220 IC chip. Best guess that it
is a software version or emulater for the TI "speech chip" Perhaps
someone from the Texas Instruments "speech labs" would know someone who
might have worked with it about 20 years ago.

Thank you very much, Bob I, You are right, this algorigthm is for TI chips,
I have a software version about it , But I don't know it's data format, this
algorithm is different from standard LPC-10/LPC-10E, It's very difficult to
unstandard it without data format explain.

Please help me, Thanks.

Best Regards
