Hi my requirement is in one single FPGA CHIP(virtex -4) i have to run Linux and some other digital logic which is written in VHDL.
my question is is it possible to run Linux and vhdl code simultaneously.
if it is possible how I can exchange the data between Linux and VHDL code

Of course it is.. You need to create a custom peripheral that attaches to the PLB bus and controls your custom logic. Once you do that, you can either create a custom linux driver to control the peripheral, or write a user space app that maps the peripheral's memory map to user space memory.
