] Here is an example of System-On-Chip (SOC) from
] Flextronics Semiconductor. It is a 32-bit general-purpose
] microcontroller implemented on UMC 0.18um targetting
] embedded applications with maximum clock frequency of
] 160MHz.

This is kind of neat... You can download VHDL for this CPU and drop it on an FPGA... Good educational tool at least.

Chips based on open cores hit the market
