-- 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.
