读取外部RAM的状态机
RAM接口OE,输出使能
WR,低电平写RAM
AB【7:0】地址总线
DB【7:0】地址总线
//将RAM 0至127的数据读出并相加最后的结果存入地址254(低8位)255(高8位)
-State machine reads the external RAM RAM interface OE Output Enable WR, low-level to write RAM AB [7:0] address bus DB [7:0] address bus// RAM 0 to 127 data read-out and phase plus the final result is stored in the address 254 (8) 255 (8 high)
