Directory-based cache coherenceIn computer engineering, directory-based cache coherence is a type of cache coherence mechanism, where directories are used to manage caches in place of bus snooping. Bus snooping methods scale poorly due to the use of broadcasting. These methods can be used to target both performance and scalability of directory systems. In the full bit vector format, for each possible cache line in memory, a bit is used to track whether every individual processor has that line stored in its cache.
R10000The R10000, code-named "T5", is a RISC microprocessor implementation of the MIPS IV instruction set architecture (ISA) developed by MIPS Technologies, Inc. (MTI), then a division of Silicon Graphics, Inc. (SGI). The chief designers are Chris Rowen and Kenneth C. Yeager. The R10000 microarchitecture is known as ANDES, an abbreviation for Architecture with Non-sequential Dynamic Execution Scheduling. The R10000 largely replaces the R8000 in the high-end and the R4400 elsewhere.
Clarkdale (microprocessor)Clarkdale is the codename for Intel's first-generation Core i5, i3 and Pentium dual-core desktop processors. It is closely related to the mobile Arrandale processor; both use dual-core dies based on the 32 nm Westmere microarchitecture and have integrated Graphics, PCI Express and DMI links built-in. Clarkdale is the successor of the Wolfdale used in desktop Intel Core 2, Celeron and Pentium Dual-Core processors.
Hierarchical storage managementHierarchical storage management (HSM), also known as Tiered storage, is a data storage and Data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid state drive arrays, are more expensive (per byte stored) than slower devices, such as hard disk drives, optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations.
Coffee LakeCoffee Lake is Intel's codename for its eighth-generation Core microprocessor family, announced on September 25, 2017. It is manufactured using Intel's second 14 nm process node refinement. Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores (along with hyper-threading in the case of the latter) and Core i3 CPUs with four cores and no hyperthreading. On October 8, 2018, Intel announced what it branded its ninth generation of Core processors, the Coffee Lake Refresh family.
Vortex86The Vortex86 is a computing system-on-a-chip (SoC) based on a core compatible with the x86 microprocessor family. It is produced by DM&P Electronics, but originated with Rise Technology. Vortex86 previously belonged to SiS, which got the basic design from Rise Technology. SiS sold it to DM&P Electronics in Taiwan. Before adopting the Vortex86 series, DM&P manufactured the M6117D, an Intel 386SX compatible, 25–40 MHz SoC. Vortex86 CPUs implement the IA-32 architecture but which instructions are implemented varies depending on the model.
