Has anybody tried to interface an i2s audio chip to the propellor? This is a synchronous serial protocol, not a typo of i2c! It is useful for hi-fidelity ADC & DAC chips.
I thought about connecting a I2S codec to the propeller, because it seems
to be fast enough to handle the interface in realtime.
But it would not be of much use. The Propeller is not a DSP and not
a good choice for signal processing.
Well, the MUL instruction would help. If you look at the propellor chip as a 10-bit digital audio synthesizer, there are a lot of cool synthesizer-type things that could be built with very low component count and a nice operator interface. There have been some nice sound files posted on this forum. But there are so many very cheap 16-bit audio codec chips available (AC'97 types, etc.) that I thought a cog could be dedicated to that, instead of using the cog for prop ADC/DAC.
