Well my problem stated when i had my vhdl code up and running on my Spartan-3a but needed to send and receive data from it to the pc,
I need my vhdl code , so i went for a microplaze structure , problem is I cant understand how will my vhdl code and microblaze co-exist at the same time because every time i program fpga with SDK it deletes my vhdl off the fpga and vise versa with ISE, I dont want to use custom peripherals except if this is the only solution.
Some people just tell me to just use microblaze hdl files produced by edk , OK but then arent I using an unprogrrammed MicroBlaze???
And do i need to go throght all of this just to be able to communicate with my vhdl code through pc(NO I CANT USE R232 since i need a speed of 56Mbit/sec)
So here is what i don't understand:
1-IF you implemented microblaze through hardware(HDL from edk to ISE) , isnt it then an un-proggrammed processor?
2-pEOPLE TELL ME i can let microblaze and my vhdl code see each other through GPIO , again how will i implement GPIO and how to connect it to both microblaze and my vhdl code , and how to program microblaze while it in hardware in this situation.
Please any help , its kinda a mess.
