我们可以用np.inner(v, w)来得到这两个向量的点积,但是由于一维数组的形状为(m,),我不喜欢使用它们,因为在(m,)中失去了第二维,如果我们使用2D数组定义v和w,则不喜欢使用它们: v = np.array([[1], [3], [5]]) w = np.array([[2], [4], [6]]) 我们可以通过转换这些向量中的一...
与未压缩数组(unpacked arrays)不同,它存储为一组连续的位,没有未使用的空间。 可以看到向量在存储时是连续存储的,与后文要介绍的未压缩数组不同 packed arrays的维数定义在变量标识符之前 unpacked arrays的维数的定义在变量标识符之后 5.数组(unpacked arrays) SystemVerilog允许声明网络、变量和用户定义类型的一维...
For example, let's say that I have a packed 2D array. localparam [0:2][4:0] TEMP = {5'd4,5'd9,5'd20}; So my array has three rows and each row is a 5-bit number. So, when I am trying to do something like this, it doesn't quite work !!! logic [1:0] arr; assign...
本声明如下: reg [7:0] register_file [3:0] = 0; 产生此错误: Error (10673): SystemVerilog error at simpleprocessor.v(27): assignments to unpacked arrays must be aggregate expressions 首先,我使用的是Verilog,而不是SystemVerilog,那么为什么它给了我一个SystemVerilog错误?第二,造成这个错误的原因是...
Muultidimensional Packed Arrays 多维打包数组仍然是一组连续的位,但也被分割成更小的组。 Example #1 下面显示的代码声明一个占用32位或4个字节的2D打包数组,并循环访问段并打印其值。 moduletb;bit[3:0][7:0] m_data;// A MDA, 4 bytesinitialbegin// 1. Assign a value to the MDAm_data =32'...
For dynamically-sized arrays, like queues, dynamic, and associative arrays, you need to make sure each array element gets sized before accessing the next layer. int c[][$][int]; initial begin c= new[4]; // creates an array of 4 empty queues foreach(c[i]) repeat(i+1) c[i]....
similarly a 2D array of bits would be declared as: logic [#cols-1:0][#rows-1:0][#bits-1:0] bt1; A nice feature of using packed arrays instead of unpacked arrays is you can treat the array variable in assignments as a rows*bits wide bit vector and assign all the array value...
(2) You can't use multidimensional arrays in ports in verilog. Use DATA[255:0] instead and manually assign bit fields. (3) Use the <CODE> block feature of this forum. It makes your code MUCH easier to read and understand. Translate 0 Kudos Copy link Reply ...
