Does anyone know if this exists?
A chip with 8 I/O's on one side and 8 on the other... Any of the 8 I/O's on one side could be mapped to any of the 8 on the other side. Preferably it would be controlled with some sort of serial protocol and have the ability to be remapped on the fly.
I tried some google searches, but could not find anything. I heard a FPGA could accomplish this, but I don't know a lot about FPGA's and it seems that would be overkill.
