 交通灯控制器控制红（r）、绿（g）、黄（y）三种不同颜色的交通灯，这三种不同颜色灯的亮、灭分别由三个定时器（timer1、timer2、timer3）控制；  当某个定时器工作时，它所控制的交通灯亮，直到设定的定时时间到（该定时器状态由’0’变’1’），交通灯跳转到另一种状态；  clk是脉冲控制端（图中未标出）；reset是异步复位端，复位状态为红色交通灯亮；  输出端r、g、y分别表示三种颜色交通灯的亮、灭状态。 ( traffic light controller control red (R), green (g), yellow (y) three different colors of traffic lights, three different colors of bright lights, off by three timer (Timer1, Timer2, Timer3 ) control  When a timer work, it controls the traffic lights, until the set timing (the timer status ' 0 ' for ' 1' ), traffic lights Jump to another state  clk is the pulse control terminal (not shown) reset is asynchronous reset terminal, the reset state for the red traffic lights  output terminal r, g, y represent the three colors of traffic lights bright, the off state.)

Synchronous DRAM (SDRAM) has become a mainstream memory of choice in embedded system memory design due to its speed, burst access and pipeline features. For high-end applications using processors such as Motorola MPC 8260 or Intel StrongArm, the interface to the SDRAM is supported by the processor’s built-in peripheral module.
