Default Hve to know the pin connection between cpld and fpga in my design

Hi Friends,

In my board i have SRAM, Spartan-3 FPGA ,CPLD Xc95144xl and PC104
Connector (ISA bus header). I want to pass the data stored in SRAM to
PC104 . in between that with the help of spartan-3 only data stored in
SRAM.

____ ______ ______ _______
|pc | | | | | | |
|104 | <----> | CPLD | <----> |SP-3 | <---> | SRAM |
|____| |______| |______| |_______|


This is connection between those components. between the sp-3 and sram
i passed 16 bit data line and address pin from sp-3 and some control
pins. Now i want to know how many pin shud be connected between cpld
and sp-3. so that data pass from sram to pc104.

Kindy give me some suggestions.

Regards

Senthil Chett.
