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

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…

@Karl -- sure multiple banks/channels can offer concurrent read/write, or even multiply sourced reads/write -- but each channel still has the native single access or burst fill performance timings.

Now look at the last three figures above, where Cadenc…
