I have several common issues:
(1) who know how to send data from FPGA to PC usb port? I found a usb ip core, but i think it's not easy to use.
(2) did any of you try convert matlab code to verilog code? is it good or not?
(3) can microblaze deal with float point calculation?
It's very difficult to solve math problems in fpga, is there any good suggestion?
Thanks very much.

hi
1)as u say u can use IP core for communicate FPGA to pc.
2)yes...matlab have a toolbox to convert matlab code to verilog..search between toolbox..u can easy find it
3)microblaze micro controllers are like the other ones(AVR,8051,...) but this type of micro controllers are powerful.i don't use it ability for computing float point.

I down load a USB controller core, it's not difficult to find it on opencores, but it's not easy to use. I am still trying it.
(1)For matlab simulink based solution, Do i need to convert it to verilog code then use ISE to compile every time?
The matlab toolbox, you need to write control file, it's not easy, and I didn't find any good tutorial to write a control file.
(2) Dose someone have some microblaze based design examples can share for learning?
Thanks very much.

if u want to use matlab simulink u have to setup ISE and make a connection between matlab and ISE.during installation ISE some library add to matlab simulink.the best tutorial is ISE getting started.its help u.some example exist in Xilinx site.
i have some micro blaze example.if i found them i share here them.

can you send some examples to me: shenhe@knights.ucf.edu

Is there anyone working with fpga board from opalkelly?
I want to use the usb port on it to receive data, don't know how to do that? any suggestions?
