Detailed Description

VHDL uses the concept of "array of type".

A multi-dimensional array is an "array of array". As a result, a multi-dimensional array is a recursive data structure. The current "top" represents the current highest dimension.

A note on array indexes:

If array A has three dimension, it will be index by A(k, j, i). Incrementing "i" will reference sequential array elements. So, assuming that all bounds start at zero, the index expression will be 


      index = i + ((j  + (k * size_dim2)) * size_dim2)

?? Should the "delta" from zero also be included here, to aid in generating code for index expressions. ??
