はじめに
Bluespecがgithubに公開している下記の3つCPUコア
- Piccolo: 3-stage, in-order pipeline
- Flute: 5-stage, in-order pipeline
- Toooba: superscalar, out-of-order pipeline, slight variation on MIT's RISCY-OOO
BluespecとVerilatorにてシミュレーションができます。
RISCV GCC のインストール
riscv64-unknown-elf-gcc をビルド＆インストールします。
を参考にしました。
Bluespec のインストール
Bluespecのインストールは、BluespecのAWSteria_Infraを調べる(その1) の最初にやっているのでそこを参照してください。
Bluespecのビルド後にインストールディレクトリをPATHに追加します。
Verilatorの準備
Verilatorは、v5.002 を使います。v5.002 より前のバージョンではビルドできない可能性があります。
Piccolo のビルドと実行
Piccolo の repo を clone 後、
git submodule update --init --recursive
cd builds ls RV32ACDFIMSU_Piccolo_bluesim RV32ACIMU_Piccolo_DM_verilator RV32ACIMU_Piccolo_verilator RV64ACDFIMSU_Piccolo_verilator RV64ACIMU_Piccolo_verilator RV32ACDFIMSU_Piccolo_iverilog RV32ACIMU_Piccolo_bluesim RV64ACDFIMSU_Piccolo_bluesim RV64ACIMU_Piccolo_bluesim Resources RV32ACDFIMSU_Piccolo_verilator RV32ACIMU_Piccolo_iverilog RV64ACDFIMSU_Piccolo_iverilog RV64ACIMU_Piccolo_iverilog
色々なコンフィギュレーションがあります。ここでは、RV64ACDFIMSU_Piccolo_bluesim と RV64ACDFIMSU_Piccolo_verilatorをビルドおよび実行してみます。
$ cd RV64ACDFIMSU_Piccolo_bluesim $ make all $ make test make -C ../../Tests/elf_to_hex make[1]: Entering directory '/mnt/c/Users/haray/home/src/Piccolo/Tests/elf_to_hex' make[1]: 'elf_to_hex' is up to date. make[1]: Leaving directory '/mnt/c/Users/haray/home/src/Piccolo/Tests/elf_to_hex'
ここで elf を hex に変換するプログラムをビルドしています。
../../Tests/elf_to_hex/elf_to_hex ../../Tests/isa/rv64ui-p-add Mem.hex
c_mem_load_elf: ../../Tests/isa/rv64ui-p-add is a 64-bit ELF file

Min addr: 80000000 (hex)
Max addr: 80001047 (hex)
Writing mem hex to file 'Mem.hex'
ここで elf_to_hex プログラムで elf を Mem.hex に変換しています。
以下、シミュレーションが実行されます。
Subtracting 0x80000000 base from addresses

elf_to_hex のビルド
各CPUの Tests/elf_to_hex ディレクトリにて、make を実行すると、次のようなエラーが発生しました。
$ make gcc -o elf_to_hex elf_to_hex.c -lelf /tmp/cc5Eu4vv.o: in function `c_mem_load_elf': elf_to_hex.c:(.text+0x248): relocation truncated to fit: R_X86_64_PC32 against symbol `bitwidth' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x28a): relocation truncated to fit: R_X86_64_PC32 against symbol `bitwidth' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x373): relocation truncated to fit: R_X86_64_PC32 against symbol `min_addr' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x37e): relocation truncated to fit: R_X86_64_PC32 against symbol `max_addr' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x389): relocation truncated to fit: R_X86_64_PC32 against symbol `pc_start' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x394): relocation truncated to fit: R_X86_64_PC32 against symbol `pc_exit' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x39f): relocation truncated to fit: R_X86_64_PC32 against symbol `tohost_addr' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x4a2): relocation truncated to fit: R_X86_64_PC32 against symbol `min_addr' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x4b2): relocation truncated to fit: R_X86_64_PC32 against symbol `min_addr' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x4cf): relocation truncated to fit: R_X86_64_PC32 against symbol `max_addr' defined in .bss section in /tmp/cc5Eu4vv.o elf_to_hex.c:(.text+0x4f1): additional relocation overflows omitted from the output collect2: error: ld returned 1 exit status make: *** [Makefile:7: elf_to_hex] Error 1
どうやら、2GBを超えるメモリを使いたいみたいなので、gcc コマンドのオプション -mcmodel=large を付けることでエラーに無くなりました。
$ make gcc -o elf_to_hex elf_to_hex.c -lelf -mcmodel=large
おわりに
BluespecなRISC-V CPUコアをBluespec と Verilator でシミュレーションできることを確認しました。
