Ch1.6: IN-place-ly rotate a pic(NxN matrix) by 90 digree in Verilog(CPP)

这个有点像DSP FPGA Chang Choo的题目,一般是放大插值,DFT,IIR之类的Verilog题目。
题目在这:Given an image represented by an NxN matrix, where each pixel in the image is 4 bytes, write a method to rotate the image by 90 degrees. Can you do this in place?
注意,这里的循环基和index需要留心注意。
关于index的选择,可以参考这个草图:
