Description

This project is based on an implementation of MIPS I specified core by Steve Rhoads: plasma

Interface

entity plasma is

  generic(

   core_idx : natural := 0;

   FPU_FLAG : string := "OF";

   SIM_FLAG : string := "ON";

   DEBUG_FLAG : string := "OF"

  );

  port(

   clk : in std_logic;

   rst : in std_logic;

   instr_addr : out std_logic_vector(31 downto 0);

   data_addr : out std_logic_vector(31 downto 0);

   rd_mask : out std_logic_vector(3 downto 0);

   wr_mask : out std_logic_vector(3 downto 0);

   instr_stall : in std_logic;

   data_stall : in std_logic;

   instr_in : in std_logic_vector(31 downto 0);

   data_to_cpu : in std_logic_vector(31 downto 0);

   data_from_cpu : out std_logic_vector(31 downto 0)

  );

end entity plasma;

generic flags controls choice of intern components:

Intern structure

Simulative test

1. execute create_workspace.sh

2. go to (automatically create) directore "workspace"

3. execute "run.sh" script

The program executes an encoding algorithm that converts an .bmp file to .jp2 file (JPEG2000 format). Source code is from openJPEG project. The folder test/program contains simulation output (file "memory_out.mem") and a script "check_output.sh" can generate a binary from this output. By replacing the file "test.bmp" and executing script "create_test.sh" the given .bmp file will be converted by simulation run.
