Verilog, a hardware description language, is often used to design digital circuits, including those that can performfloating-point operations. There are several ways to convert a fixed-point number to a floating
1. 固定点数（Fixed Point Numbers）：在Verilog中，固定点数是一种特殊的数据类型，它表示一个有固定位数的整数。固定点数的优点是计算速度快，因为所有的算术运算都是在固定点数上进行的。然而，固定点数的缺点是精度较低，因为每个位都有一定的误差。2. 浮点数（Floating Point Numbers）：浮点数是一种更精确的...
Due to the shortcomings of BFP arithmetic, many application involving fractional decimal data are forced to perform their arithmetic either entirely in software or a combination of software and decimal fixed- point hardware. Providing decimal floating point improve the performance of such application. ...

一个出租车计价系统。 完成的功能是前3公里内收费10元,超过3公里按每公里2元收费。 同时记录等待时间,累计等待时间超过5分钟则加3元,以此类推。 若总公里数超过20公里,需加收10元空载返程费。 公里数、等待时间、费用均需显示在数码管上。 FPGA代码Verilog/VHDL代码资源下载:www.hdlcode.com ...
进行带符号定点数的加法运算。在Verilog中，可以使用"+"操作符进行加法运算。需要注意处理进位，以及溢出情况。4. 结果截断 根据实际需求，对加法运算得到的结果进行截断，得到最终的带符号定点数结果。四、示例代码 以下是一个简单的Verilog示例代码，实现了带符号定点数加法的功能：```module signed_fixed_point_...
real pi; // Declared to be of type real real freq; initial begin pi = 3.14; // Store floating point number freq = 1e6; // Store exponential number $display ("Value of pi = %f", pi); $display ("Value of pi = %0.3f", pi); ...
