There is little to no hardware support for it. Octuple-precision arithmetic is too impractical for most commercial uses of it, making implementation of it very rare (if any).
==Processing Statistics==
Since an octuple precision numeral takes up 32 bytes of storage, the requirements in-order to transport this piece of data are as follows.
* [[8-bit|8-bit architecture]] – 32 separate packets<sup>1</sup> of information (at least) in order to transport this across the main data bus
* [[16-bit|x16 architecture]] – 16 separate packets of information (at least) in order to transport this across the main data bus
* [[x86|x86 architecture]] – 8 separate packets of information (at least) in order to transport this across the main data bus
* [[x86-64|x64 architecture]] – 4 separate packets of information (at least) in order to transport this across the main data bus

<sup>1</sup>statistical extrapolation since it would take 1/8 of the entire memory just to store 1 binary256 numeral, making it completely impractical.
