Hello everyone, I would like to know if we can use a general purpose (available off-the-shelf at popular stores) USB to JTAG cable to program a Xilinx Spartan 3 FPGA or does it *have to be* a cable (and box) specifically meant for programming a Spartan 3 FPGA (as shown on the Xilinx website)? I am hoping to hear from people who have actually used a general purpose USB to JTAG cable (...

Sorry if this is a repeat post. . . I'm trying to understand the reasons why someone would put a soft ARM processor in an FPGA. Both Xilinx and Altera have fine 32-bit offerings that have good development environments, growing ecosystems, and rich catalogs of IP. I suspect it has something to do with ARM being an industry standard or something like that, but the reality is that the ARM will...

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 "indus...
