上次的因為重點是 emulator，實作上把 memory access 簡化了
但未來我們會跟 RTL 共用一組 memory 實作，需要拆分出來做一個共同的介面

  cpu.clk(clock);
  cpu.reset(reset);

  cpu.imem_req_valid(imem_req_valid);
  cpu.imem_req_ready(imem_req_ready);
  cpu.imem_req_addr(imem_req_addr);

  cpu.imem_rsp_valid(imem_rsp_valid);
  cpu.imem_rsp_ready(imem_rsp_ready);
  cpu.imem_rsp_data(imem_rsp_data);
  cpu.imem_rsp_status(imem_rsp_status);

  memory.req_valid(imem_req_valid);
  memory.req_ready(imem_req_ready);
  memory.req_addr(imem_req_addr);

  memory.rsp_valid(imem_rsp_valid);
  memory.rsp_ready(imem_rsp_ready);
  memory.rsp_data(imem_rsp_data);
  memory.rsp_status(imem_rsp_status);
