hmmm that link explains a lot!There are definitely things that FPGA's are very fast at, but they usually have pretty specific uses. They generally aren't used as direct replacements for uC's in final development. There are very fast uC's like ARM9's and ARM Cortex if you just want speed.
Someone posted this link a while ago, and it's pretty nice for beginner FPGA.
fpga4fun.com - Welcome
I don't know of any websites that have a basic overview of ARM chips. ARM is the processor core and the different manufacturers, like Atmel, NXP, ST... add all the peripherals. Changing from one ARM7 from one manufacturer to another means you'll have to rewrite the code that access the peripherals, but they are close enough that it's not that difficult.Any site on ARMs? I like to read up on those to get a better idea....
