-- DESCRIPTION:
10 
--    Implements the RAM for Spartan 3 Xilinx FPGA
11 
--
12 262 rhoads 
--    Compile the MIPS C and assembly code into "test.axf".
13 
--    Run convert.exe to change "test.axf" to "code.txt" which
14 139 rhoads 
--    will contain the hex values of the opcodes.
15 181 rhoads 
--    Next run "ram_image ram_xilinx.vhd code.txt ram_image.vhd",
16 139 rhoads 
--    to create the "ram_image.vhd" file that will have the opcodes
17 181 rhoads 
--    correctly placed inside the INIT_00 => strings.
18 139 rhoads 
--    Then include ram_image.vhd in the simulation/synthesis.
