在Verilog HDL中有两种移位运算符。 :(左移位运算符) >>:(右移位运算符) 其使用方法如下: a >> n; a n; a代表要进行移位的操作数,n代表要移几位。这两种移位运算都用0来填补移出的空位。下面举例说明: module shift; reg [3:0] start, result; initial begin start = 1; //start在初始时刻设为值...
1. Avoid clock- and reset-gating (avoid writing combinational logic on the edge part.) 2. Always blocks should: [ a. Be always_ff @(posedge clock) blocks; b. Use the nonblocking assignment operator, with a delay <= #1 ] 3. No path should set a variable more than once 4. Reset a...

The original OPL3 chip used a 14.31818MHz master clock. The sample rate was 14.31818MHz/288 = 49.7159KHz, which is quite an interesting sample rate. With 36 operator slots, that gives 8 clocks to update each operator each sample (operator logic is time-shared between slots). ...
缩减运算符(reduction operator)是单目运算符,也有与、或、非运算。其与、或、非运算规则类似于位运算符的与、或、非运算规则,但其运算过程不同。位运算是对操作数的相应位进行与、或、非运算,操作数是几位数,其运算结果也是几位数。而缩减运算符则不同,缩减运算是对单个操作数进行与、或、非递推运算,最后的...
