The Abacus Conundrum

How Hard Can it Be to Count Chips?

by Jim Turley

One of the questions we often get asked here at EE Journal Galactic Headquarters and Bait Shoppe is, “What is Company X’s market share?” or the corollary question, “How big is the total market for microcontrollers, CPUs, and FPGAs?”

After charging our customary consulting fee, plus tax and 18% gratuity, and after deducting for mileage, food, lodging, client entertainment, and out-of-pocket expenses, our reply is generally, “We don’t know.”  Read More

Why You Should Whitelist in Your Ad Blocker

posted by Kevin Morris

We understand why many people have turned to ad blockers these days. With the proliferation of websites that create miserable browsing experiences, we’re sometimes tempted to install blockers ourselves.

However, we’d like you to please consider whitelisting if you use an ad blocker. (23-Mar)

An Interesting – And Challenging – Take on Tech

posted by Bryon Moyer

I ran across a series that deals with some of the less-touted possible outcomes of the technology work we do. It’s actually a few years old, but, while edgy and possibly challenging for some to watch, I also found it thought-provoking. (1-Feb)

Reviewing the $10,000 Ethernet Cable

posted by Kevin Morris

The people who buy this cable know why they need it, and it's well worth the extra investment. "Sure," some may say, "it's just data," but the ones and zeros that arrive at the end of this cable completely transcend binarity. (10-Feb)

How Does Scatter/Gather Work?

Posted on 02/20/17 at 2:13 PM by TotallyLost

What is FAR worse?

An 8-way time division multiplexor to "fairly share" memory between 6 processors and 2 DMA channels -- no priority accesses to starve another channel, no contention based allocations, just straight channel 1 gets only time slot 1, ch…

Now you might say that no one would be that stupid as to pack all accessed data into a single subchannel. With the number of sub-channels being 2^n (where n is 1, 2 or 3), it's also pretty likely that the underlying data structure to be processed will hav…
