2.2.2.8.4 Element Ordering in the TILER Container
This section highlights how elements - 8-bit data, 16-bit data, 32-bit data or 4-kiB page - are ordered in the
container. In other words, this section highlights how the path of incrementing virtual addresses is mapped
in the container.
It is interesting to note that whatever the mode, and hence the element size, the sequence for ordering the
elements in their related container is strictly similar and only depends on the related orientation. In other
words:
•
Mode is about element granularity
•
Orientation is about change of orthornormal basis for ordering the elements in the mode-specific
container
A corollary to the previous statements is that in a given mode the internal structure of an element is
unchanged whatever the orientation. In page mode for instance, the offset of a word inside a page is
invariant by orientation; the content of a page is always accessed in the same manner.
In the next sections, the natural container orthonormal basis is referenced as: (Xn , Yn) and the oriented
orthonormal basis as: (Xo , Yo).
