Intel don't have vpintersect. Its micro-coded dog slow but its such an obscure operation and of little use if any. I'd rather AMD re-invest the hardware into speeding up useful operations, shave 1 cycle off divide or square root or something.

I found a jpeg2000 reference PDF somewhere. It may as well have been written in Mandarin. I got as far as extracting the width and height. Its much more advanced than jpeg. Forget about writing a decoder.

Human hearing is excellent. Good directional perception and sensitivity. Eyesight is the weakest sense. Poor color sensitivity, low light sensitivity, blindspot. The terrible natural design flaws are compensated by natural nystagmas and the brain filling in the blanks.
