Well, I think will not be so difficult Jeethu,
First, I will gave up in using floating point, just because
I'm more hardware than software guy :)
Then, I will carefuly define my problem. I haven't followed the subject
so I don't know if you knew what thermocouple to choose and what range do
you want to measure. There isn't an universal solution for temperature
measurement. Also cold junction compensation may be unnecesarry for
some temperature ranges, because the error induced by non-compensation may
be too small. Some thermocouples may be linearised on measuring intervals.
K is one of them. So maybe a table read with interpolation may be much
usefull. 12F675 is a nice chip and I like too. The leak of memory can be
compensated by external eeprom where a table read can be stored gently.

best regards,
Vasile
