A full 8-wide in-place triple-loop Inverse DCT may be achieved -in 7 instructions. Expanding this to 16-wide is a matter of setting +in 8 instructions. Expanding this to 16-wide is a matter of setting `svshape 16` **and the same instructions used**. Lee Composition may be deployed to construct non-power-two DCTs. The cosine table may be computed (once) with 18 Vector instructions.
