Supervisor Mode Access Prevention (SMAP) is a feature of some CPU implementations such as the Intel Broadwell microarchitecture that allows supervisor mode programs to optionally set user-space memory mappings so that access to those mappings from supervisor mode will cause a trap.
Raptor Lake is Intel's codename for the 13th and 14th generations of Intel Core processors based on a hybrid architecture, utilizing Raptor Cove performance cores and Gracemont efficient cores. [ 3 ] [ 4 ] [ 5 ] Like Alder Lake , Raptor Lake is fabricated using Intel's Intel 7 process.
An iterative refresh of Raptor Lake-S desktop processors, called the 14th generation of Intel Core, was launched on October 17, 2023. [1] [2] CPUs in bold below feature ECC memory support when paired with a motherboard based on the W680 chipset according to each respective Intel Ark product page.
Manufactured using Intel 7 process. Raptor Cove is used in the P-cores while the E-cores are still implemented using Gracemont microarchitecture. Emerald Rapids: successor to Sapphire Rapids, server- and workstation-only. Fifth-generation Xeon Scalable server processors based on the Intel 7 node.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
Intel’s CEO, Pat Gelsinger, is a true technologist who played an important role in the company’s storied past. Today, he’s faced with a difficult decision: whether to break up the iconic ...
Given an initial state in a state machine, a fail-fast system will check such a state and fail fast. Given a state-change in a state machine, the fail-fast system will halt the machine if the state-change is forbidden. It could be the case that the forbidden state-change is due to a wrong external input.
The Intel saga is a grim reminder that some of America’s greatest companies have succumbed to the four-wrong-CEOs disease. Consider Westinghouse, a jewel of American industry for 100 years.
