#-------------------------------------------------------------------------------
# This makefile does not contain any targets, only definitions used by the
# makefiles of all the code samples.
# It is meant to be included and not used standalone.
#-------------------------------------------------------------------------------
# SYSTEM PARAMETERS
#
# You can define here the default size and address of the memory blocks of the
# system as seen by the linker, though you can't change the number and type of
# blocks here (see /vhdl/mips_cache_*.vhdl and /vhdl/mips_pkg.vhdl).
#
# The samples' makefiles will probably redefine the values, anyway.
#
#-------------------------------------------------------------------------------
# NOTE:
# A link script '/src/ion_noxram.lds' was used in previous versions of the
# project. It is no longer used. It is known to be buggy and will be removed.

### System parameters ##########################################################
# FIXME clean up parameter names
# 'CODE_BRAM' is meant to be a small BRAM (2 to 4KB) used for bootstrapping.
# 'DATA_BRAM' is a small BRAM connected to the data ports, used for debugging.
# 'XRAM' is meant to be the main external RAM, either SRAM or SDRAM.
# Default location of code BRAM is on the reset vector address
CODE_BRAM_ADDRESS = 0
# Default size of code BRAM in 32-bit words
CODE_BRAM_SIZE = 1024
# Default size of data BRAM in 32-bit words
DATA_BRAM_SIZE = 256
# Default address of BRAM -- used in some simulation-only tests, see makefiles

# Default size of data external RAM (XRAM) in 32-bit words (for simulation)
XRAM_SIZE = 2048
# Default address of XRAM
XRAM_ADDRESS = 0x80000000
### Build options ##############################################################
# Don't use gcc builtin functions, and try to target MIPS-I architecture
# This will prevent usage of unimplemented opcodes but will insert nops after
# load instructions, which Ion does not need.
# (See comment above about -G0 flag)
CFLAGS = -O2 -Wall -c -s -fno-builtin -mips1 -G0
# LFLAGS: linker options are in the respective makefiles
### Project directories ########################################################
# VHDL test bench directory, where VHDL output files will be created
TB_DIR = ../../vhdl/tb
# VHDL DE-1 board demo root directory, for vhdl output
DEMO_DIR = ../../vhdl/demo
# Root test code source directory, where python script and vhdl templates are
SRC_DIR = ..
