How to implement two-dimensional array using HDL?

I need to creat many tables in FPGA, and these tables are used to store two-dimensional array data. For example, when I get (x,y) value and then find the coordinate according this (x,y) value. ...

A 2-D array (N,M) can be simply mapped to a 1-D array (N*M). If N and M are both powers of two, just concatenate the address vectors. In so far, no special functions are needed.

Dear FvM:

Good idea!

But i have another question. For my application, the N=M=9, the QII can only implement memory which depth is below 65536. It seems that i shouldn't merge samll memorys to a big one, for i must find my result according N&M's value.:cry:
