Author liable for nothing. -- 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. --------------------------------------------------------------------- library ieee; use
