A leading CPU in used in Chinese domestic computers can leak cache data from applications and operating systems due to a flaw in the chip designer's custom architecture, researchers found. Processors ...

The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the ...

LoongLeak vulnerability in Loongson 3A5000 and 3A6000 CPUs lets any unprivileged program read disk encryption keys and root ...

The purpose of this application note is to familiarize the reader with the Level 1 (L1) CPU cache implementation in the PIC32MZ device family by bringing awareness to the hazards that can occur in a ...

I'm studying for the A+ exam, so the questions are coming in droves for now. Now that L2 cache has been integrated into the processor and runs at full speed, what differentiates it from L1 cache? I'm ...

Once again, a novel "speculative execution side-channel" attack has been discovered by researchers. They show in their paper on the attackthat it will work against modern Intel microprocessors. Intel ...

I was checking out the specs at intel.com and noticed that the P4 has something called "12K µops L1 Execution Trace Cache" which is "8KB L1 data cache" The Pentium III has 32K L1 Cache (16K for ...

Some design teams creating system-on-chip (SoC) devices are fortunate to work with the latest and greatest technology nodes coupled with a largely unconstrained budget for acquiring intellectual ...
