I2C master controller problme

[dolby.yang]

Hi,
Currently i want do a I2C master controller for AT24C512B eeprom，i searched the ip core for I2C on net, that is not fit for 24C512b ,because 24C512b random read operation need 2 word address following the device address ,i saw the i2c core on net most of them are one word address for eeprom .

So who have I2C code for this application ?

I2C ip cores belongs to nxp (now philips) contacting them would give you a better perspective of the options...

I thinks two offset is not a problem, while use opencore's i2c master, for example read a single data from i2c memory,the operation will be S(start)-a0(device address)-offset-RS(repeat start) a1-read data-nack+P, we should send CR 90 10 10 90 10 68
while you want to send two offset, you just need to send one more 10 CR to write a extra offset that mean 90 10 10 10 90 10 68
