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