If you are interested in a resonably recent processor, take a look at the
Intel 80960SB. 

	Summary:	(from the data book)

	32 bit internal, 16 bit external data.
	32 bit multiplexed address bus
	5 Mips at 16 Mhz
	4 Direct interrupt pins
	F.P. performance: (in usec)

			32 bit	64 bit
	Add		0.6	0.8
	Subtract	0.6	0.8
	Multiply	1.1	2.0
	Divide		2.0	4.5
	
	Price - talk to Intel. I think I heard a price of $25 in quantity
	mentioned at some stage (But that might have been the 80960SA).
	A GNU based C compiler is available.
