No product gets built without at least one good supply chain war story – especially true in these strange times. Before we get into the details of the story, I feel it’s worth understanding a bit more about the part that caused me so much trouble: what it does, and why it’s so special.
Ethernet rules everything around us, a large proportion of our systems communicate to each other with ethernet somewhere in the line. And the fast pace race to the bottom for embedded systems means that almost all network equipment is smart to some degree these days.
If I multiply two 64-bit integers (having values in [0, 264)), the product requires 128 bits. Intel and AMD processors (x64) can compute the full (128-bit) product of two 64-bit integers using a single instruction (mul). ARM processors, such as those found in your mobile phone, require two instructions to achieve the…
