Re: Nov 26 - Day 1: Implementing USB in Embedded Products

NO RATINGS
Hello,

I am interested in having a cpu communticate with a "smart" power supply controller, or controllers.  I am interested in using USB for interconnections between host and "device" rather than use boards communicate using ISA bus, or even PCI bus--using the PC104 format.  This would drastically reduce the number of I/O connections to the FPGA on the "device" which must communicate with the host.  I need to know if the protocol is simpiler to implement that the alternative protocols.  I don't know the USB protocol AT ALL.  So, would I gain anything using USB bus rather than ISA?  What is required in the "device" to communicate over USB?  Can I implement the protocol without the need for a CPU in my controller's  FPGA?  This question is particularly of interest to me.  I imagine the host (PC104 CPU)  has plenty of software support already to communicate, but what do I need in my smart controller ("device") to communicate over USB? 

Thank you.

Greg
