减1计数器 一、设计要求 用Verilog HDL语言设计一个计数器。 要求计数器具有异步置位/复位功能,可以进行自增和自减计数,其计数周期为2^N(N为二进制位数)。 二、设计原理 输入/输出说明: d:异步置数数据输入; q:当前计数器数据输出; clock:时钟脉冲; count_en:计数器计数使能控制(1:计数/0:停止计数); updown:计数器进行自加/自减运算控制(1:自加/0:自减); load_d-a counter a reduction, design requirements using Verilog HDL design of a counter. Asynchronous requests with counter-home/reset functions can be carried out by self and self-count reduction, cycle counting of 2 ^ N (N for binary digit). Second, the principle of design input/output Description : d : asynchronous home several data input; Q : The current counter data output; Clock : clock pulse; Count_en : Counting enable control (1 : Counting/0 : Stop counting); Updown : dollars several self-Canada/reduction Operational control (1 : Since the plus/0 : Since decrease); load_d

于 RZV分布 的电流采样方法 。仿真结果证实该方法简单可行 。 -: Random pulse width modulation speed control system to solve the exchange of acoustic noise in a direct and effective way. Random zero vector distribution is a good random method, but the asymmetrical switching function so that it does not apply to the traditional current sampling methods. PWM cycle through the simulation shows that the mid-point sampling methods can not be an accurate, on average, the analysis of asymmetric mode ripple current caused by the impact on the current average value based on the proposed distribution of a suitable RZV current sampling methods. The simulation results confirmed that the method is simple and feasible.
