Suppose little Gauss lived in the modern age. Little Gauss’ teacher wanted to surf the internet, so he assigned all of his students the following integral to evaluate:

$$ \int_0^1 x^{100} e^{x-1} dx $$

Being the clever alter-ego of the boy who immediately saw $\sum^n_k k = {n+1 \choose 2}$, little Gauss constructed a sequence

$$ s_k = \int_0^1 x^k e^{x-1} dx $$

and with a little bit of clever manipulation (integration by parts), he found that, using $u_k = x^k$, $dv = e^{x-1}dx$, $v = e^{x-1}$

Caching ASTC Parameters to Disk

Intro

Here's a negative result around compressing and caching ASTC parameters to reduce transfer overhead.

Taking an Adreno 650 as our reference:

1. GPU - 1.2 TFlops (1200 GFlops)
2. CPU SIMD int8 - 18 GFlops
