Description: 8位十六进制频率计设计 根据频率的定义和频率测量的基本原理，测定信号的频率必须有一个脉宽为1s的输入信号脉冲计数允许信号；1s计数结束后，计数值被锁入锁存器，计数器清零，为下一测频计数周期做好准备。测频控制信号可由一个独立的发生器（FTCTRL）来产生。-8-bit hexadecimal Cymometer designed in accordance with the definition of frequency and frequency of the basic principles of measurement to determine the frequency of the signal must have a pulse width of the input signal for 1s permit pulse counting signal 1s counting after the total value was locked into the lock depositors, counters cleared for the next count cycle frequency measurement ready. Frequency control signal generator may be an independent (FTCTRL) to generate. Platform: |

Description: 系统设置一个两位BCD码倒计时计数器（计数脉冲1HZ），用于记录各状态持续时间；
因为各状态持续时间不一致，所以上述计数器应置入不同的预置数；
倒计时计数值输出至二个数码管显示；
程序共设置4个进程：
① 进程P1、P2和P3构成两个带有预置数功能的十进制计数器，其中P1和P3分别为个位和十位计数器，P2产生个位向十位的进位信号；
② P4是状态寄存器，控制状态的转换，并输出6盏交通灯的控制信号。-System to set up a two BCD code countdown counter (count pulse 1HZ), used to record the duration of each state because the duration of each state are inconsistent, so these counters should be placed in several different presets countdown of numerical output to two digital display procedures were set up four processes: ① process P1, P2 and P3 form two functions with a preset number of decimal counters, of which P1 and P3, respectively, for months, and 10-bit counters, P2 to generate a 10-bit The binary signal ② P4 is the status register, control the state of the conversion, and six output control signals of traffic lights.

Description: Implementation of GPU (Graphics Processing Unit) that rendered triangle based models. Our goal was to generate complex models with a movable camera. We wanted to be able to render complex images that consisted of hundreds to thousands of triangles. We wanted to apply interpolated shading on the objects, so that they appeared more
smooth and realisitc, and to have a camera that orbitted around the object, which allowed us to
look arond the object with a stationary light source. We chose to do this in hardware, because our initial implementation using running software on the NIOS II processor was too slow. Implementing parallelism in hardware is also easier to do than in software, which allows for more efficiency. We used Professor Land s floating point hardware, which allowed us to do calculations efficiency, which is essential to graphics. Platform: |
