How To Implement Virtual Memory, Part 2

Now You See It, Now You Don’t

by Jim Turley

Earlier this week we looked at one of the most useful ways to leverage virtual memory. But there are other reasons for cracking open your chip’s MMU to see what secrets it holds. One is demand paging and the other page-level protection. Both features are built in to every x86 processor, as well as most other CPUs like ARM and RISC-V. 

Best of all, these virtual memory techniques aren’t mutually exclusive. You can implement address translation and demand paging and protection if you want to. All it takes

Speeding Up Large-Scale EM Simulation of ICs Without Compromising Accuracy

Sponsored by Cadence Design Systems

With growing on-chip RF content, electromagnetic (EM) simulation of passives is critical — from selecting the right RF design candidates to detecting parasitic coupling. Being on-chip, accurate EM analysis requires a tie in to the process technology with process design kits (PDKs) and foundry-certified EM simulation technology. Anything short of that could compromise the RFIC’s functionality. Learn how to get the highest-in-class accuracy and 10X faster analysis.

Common Design Pitfalls When Designing With Hall 2D Sensors And How To Avoid Them

Sponsored by Texas Instruments

This article discusses three widespread application issues in industrial and automotive end equipment – rotary encoding, in-plane magnetic sensing, and safety-critical – that can be solved more efficiently using devices with new features and higher performance. We will discuss in which end products these applications can be found and also provide a comparison with our traditional digital Hall-effect sensors showing how the new releases complement our existing portfolio.

OneDrive Down the Road to Madness
I feel your pain. I also fell into the OneNote/OneDrive trap. I use OneNote a lot, and I naively upgraded to the newer slick-looking version a few years ago before realizing that, unlike all previous versions, it doesn't store a local copy of your notes. It's all in OneDrive ...

OneDrive Down the Road to Madness
Great article! And funny-angry-self-righteous commenter who claims "it works for me." He is clueless. I bought a new Windows 10 laptop a few months ago and copied MBs of files from my old PC to my new PC using a thumbdrive. I didn't even know the concept of ONEDRIVE existed and ...

Neuromorphic Revolution
No More "Times Lower Than" Hey Marketers and PR folks - this one's for you. In researching this article I repeatedly ran into official, presumably copy-edited materials that made claims that power was "75X lower" or "30 times less than" other solutions. This is absolutely wrong. Your audience for these materials ...
