I'm trying to understand what the advantage of putting a soft
implementation of an ARM in an FPGA (Altera or Xilinx) is. The reason I
ask is both of them have entirely adequate 32-bit soft processors of their
own. Each has a nice development environment with lots of IP, growing
ecosystems, and will run easily 3x to 4x the clock speed of the soft ARM.
I suspect it has something to do with "industry standard blah blah blah" or
"good third party support" or something, but I'm trying to really
understand the technical advantages.
