need Tips on increasing performance of an I2C driver

Hi,

Can someone share some tips on how to increase the performance of an
I2C driver code .
My driver code do an EEPROM access via cpld, and performance is not as
expected.

Which CPLD, and what does "not as expected" mean ?

You could also add:

Which processor?

Hardware or bit-banged interface?

What language?

Clock out the data as fast as the I2C chip will take it.
If your micro is not upto that then increase micro clock or find a
better micro.
