Which CPU to choose?

I've looked at farnell, there are some 450 MPUs and thousands of MCUs,which one should I learn, considering:I'm currently using a standard x86-32 PC for my project,but would like to replace the whole motherboard withjust two chips: cpu and memory.The code for x86 is written (by me) in ASM, about 64k in size.This is what I need:1. 32-bit CPU2. 128k of internal CODE memory, ISP and IAP. (in-system, in-application programmable)3. min 32MB of DATA memory. (maybe SDRAM, directly connected to CPU)4. embedded FPU (or a free, precise library).5. QFP package (not BGAs).6. price: under 30 EUR.7. free develepment tools.My knowledge is: Z80, C51 and x86, ASM only.

I see TI have a new DSP $79 Eval

This has SDRAM, Flash, 120Mhz (Claims 240Mips), and includes High speed USB. Looks like you could benchmark it quite cheaply, just grab the ezdsp, and run some test code.
