這次擴展 Dual Issue In Order CPU 把它變成 Out of Order
rtl 的部分多了：
rtl/control/free_list.sv
rtl/control/rename_control.sv
rtl/control/ooo_scheduler.sv
rtl/tops/tiny5_dual_ooo.sv

順帶擴充了 systemC 的部分，讓他也支援 Dual Issue Out of Order CPU

只加上 dual issue Out of Order CPU 實作，一樣會發現 cycle count 對不起來：

6: [PASS] random arithmetic seed 1 [normal] rtl_cycles=2868 systemc_cycles=2984 retired=256
6: [PASS] random arithmetic seed 1 [stalled] rtl_cycles=3020 systemc_cycles=3133 retired=256
6: [PASS] random arithmetic seed 2 [normal] rtl_cycles=2793 systemc_cycles=2923 retired=256
6: [PASS] random arithmetic seed 2 [stalled] rtl_cycles=2944 systemc_cycles=3059 retired=256

加上 systemC 的 Dual Issue Out of Order C-model：

7: [PASS] random arithmetic seed 1 [normal] rtl_cycles=2868 systemc_cycles=2868 retired=256
7: [PASS] random arithmetic seed 1 [stalled] rtl_cycles=3020 systemc_cycles=3020 retired=256
7: [PASS] random arithmetic seed 2 [normal] rtl_cycles=2793 systemc_cycles=2793 retired=256
7: [PASS] random arithmetic seed 2 [stalled] rtl_cycles=2944 systemc_cycles=2944 retired=256
