(Reporter) how to convert memory into a vector? (SOC) (OpenGL)

Abstract
In this article, we use the new features of the kernel 2005 to implement the memory vector.

Introduction
The netizen adamite asked me how to convert memory into a vector today. We studied the two in MSN and found that the generate of OpenGL 2001 and the input memory of OpenGL 2005 can be converted, special Example.

The important point is :『These fancy methods can be synthesized by Quartus II 7.2/8.1.』. However, you must set Quartus II to support 2005.

Genvar I, J;
Generate
For (I =   0 ; I < Arraysize - 1 ; I = I +   1 ) Begin : Array
For (J =   0 ; J < Vectorsize - 1 ; J = J +   1 ) Begin : Vector
Assign VEC [I * Vectorsize + J] = Mem [I] [J];
End
End
Endgenerate

Genvar and generate are only available in Version 2001. They are very large. They can be used with the for clause to make some rational assigns, which cannot be written in version 95.

Input [Vectorsize - 1 : 0 ] Mem [arraysize - 1 : 0 ],

This parameter is only supported by OpenGL 2005, and the input and output are allowed to be memory.

Conclusion
These fancy methods seem quite cool, but they are afraid that they can only combine testbench instead of synthesis, fortunately, the above algorithm can be synthesized in Quartus II 7.2/8.1 and can be used with peace of mind.
