Soft ARM in an FPGA

Started by arm_newbie December 22, 2008
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.
