there are many document or sw /hw resources about embedded system development, specially for C51, ARM platform.
but I'm sorry, it's all chinese web site. if you don't know chinese, maybe you need get the help of dictionary.
Ha, I know the most simple way to efficient reduce the pin count is pin sharing. Smart*MPEG even sharing pin between four kinds function point.
that is to say, many functions of Smart*MPEG can't be used at same time.
And to reduce the additional ground and power pin is hard and need technology...

I am not clear why you need two I2C bus. I2C bus can be used to connect more than one devices via only two pins SDA and SCL.
-> I think the I2C bus is an important extension bus for DVB device.
You may necessary to control E2PROM, RF tuner/demodulator ,Audio DAC, Frontpanel...

we are developing an mpeg-2 decoder chip with two TS SPI/one IDE/one uart/one ethernet RMII interface/two smart card interface/16 bit flash/32bit sdram interface/pcm &spdif audio interface/3 way video DAC analog out / CEIR /two I2c /CSPI(connect to VFD ctrl IC on board) /GPIO and...
Anybody who can help me with some recommendation of powerful hdtv decoder soc solution?
and if you have datasheet to describe the chip, pls attach it as reference.
