Security: Hard and Soft

Next Up: A Tortoise That Checks Your Chip for Flaws

by Jim Turley

I hate writing about security. I hate it because I wish it were unnecessary. There was a time when engineering meant making a product that did what you wanted it to do. Now it means spending a bunch of time making it not do what other people want but you don’t want. This sucks.

Most of the problem with implementing security features is guessing where the vulnerabilities are. How do you fix a bug you’ve never even thought of, much less identified? At least “real” hardware bugs are unintentional. Security hacks are both deliberate and malicious. Someone is trying to break your stuff.  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…
