Guys thanks fr your suggestions but actually I need to design an FPGA which would act as an interface with 8751 and i2c bus.
I checked Philips site but most of the block diagrams contain just a block saying i2c control logic.
I need to find out what exactly lies in that block.
when I write i2c memory, 8751 shudnt realise that ... it shud feel like its an ordinary mem. So software control is out of question.

and of course design of FPGA does involve coding in VHDL initially.
Can anybody suggests more links ?
