software - Proper term for electronic-ize(ing) an algorithm

Let us consider a certain computer program that converts sine values to cosine values:

#!/usr/local/bin/python

import math

for _ in range(0, 90, 0.1):
    x = math.sin(_)
    print(  math.cos( math.asin(x) )  )

Now, I want to do it on-chip/in-hardware so I make something like:

So what is this process of implementing a math algorithm on circuit is called?

Actually, I read Apple's blog

To achieve long battery life when playing video, mobile devices must decode the video in hardware; decoding it in software uses too much power. _{^{Sir Steve Jobs}}

and that got me inspired to implement some of my algrothims in-circuit. So what is this process called? ^{_{here's another example}}

What do I search for in library- hardwiring, circuitification or what exactly?
