Multiplication on a common microcontroller is easy. But division is much more difficult. Even with hardware assistance, a 32-bit division on a modern 64-bit x86 CPU can run between 9 …read more Continue reading Faster Integer Division with Floating Point
Security leaders are facing big decisions about how they use their monetary and people resources to better secure their environments.
The post Consolidation vs. Optimization: Which Is More Cost-Effective for Improved Security? appeared first on Securit… Continue reading Consolidation vs. Optimization: Which Is More Cost-Effective for Improved Security?
At first glance, getting a computer program to run faster than the first electronic computers might seem trivial. After all, most of us carry enormously powerful processors in our pockets …read more Continue reading 50-Year-Old Program Gets Speed Boost
In CPU design, there is Ahmdal’s law. Simply put, it means that if some process is contributing to 10% of your execution, optimizing it can’t improve things by more than …read more Continue reading Optimizing Linux Pipes
For the majority of workloads, fiddling with assembly instructions isn’t worth it. The added complexity and code obfuscation generally outweigh the relatively modest gains. Mainly because compilers have become quite …read more Continue reading AVX-512: When The Bits Really Count
When it comes to programming, most of us write code at a level of abstraction that could be for a computer from the 1960s. Input comes in, you process it, …read more Continue reading Modern CPUs are Smarter Than You Might Realize
[Jay Carlson] has shared some fantastic guidance on how to optimize one’s home workspace, and you just might want to emulate some of his layout, especially if you routinely juggle …read more Continue reading How To Optimize Your Workspace: Analyze How You Work
This post will shed some light on how we were able to optimise one of our frontends, reducing the typical project’s run time by half. We’ll also take a look at some of the pitfalls we encountered and how we can apply our changes to other projects as we… Continue reading An Optimisation Story: Building a Code Scanner for Large Golang Apps
On a recent rainy afternoon, [Thanassis Tsiodras] decided to build his own Forth for the Arduino to relieve the boredom. One week of intense hacking later, he called it done …read more Continue reading DIY Forth on Arduino
High-level programming languages do a great job of making a programmer’s job easier, but these languages often leave a lot of efficiency on the table as a compromise. While a …read more Continue reading Honey, I Shrunk the Arduino Core
