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:

flag	meaning
core_idx	for many core simulation this flag identifies particular core (simulation only)
FPU_FLAG	"ON" activates simulative FPU components
SIM_FLAG	"ON" activates calculation from extern libraries and accelerates simulation, "OF" makes the core synthesizable
DEBUG_FLAG	"ON" activates verbose debugging output, each register file access is reported (simulation only)

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.
