Sunny Cove
Sunny Cove is a codename for a CPU microarchitecture developed by Intel, first released in September 2019. It succeeds the Palm Cove microarchitecture and is fabricated using Intel's 10 nm process node. The microarchitecture is implemented in 10th-generation Intel Core processors for mobile (codenamed '' Ice Lake'') and third generation Xeon scalable server processors (codenamed ''Ice Lake-SP''). 10th-generation Intel Core mobile processors were released in September 2019, while the Xeon server processors were released in April 6, 2021. There are no desktop products featuring Sunny Cove. However, a variant named Cypress Cove is used for the 11th-generation Intel Core desktop processors (codenamed ''Rocket Lake''). Cypress Cove is a version of the Sunny Cove microarchitecture backported to Intel's 14 nm process node. The direct successor to the Sunny Cove microarchitecture is the Willow Cove microarchitecture, which powers the 11th-generation Intel Core mobile processo ...

Ice Lake (microprocessor)
Ice Lake is Intel's codename for the 10th generation Intel Core mobile and 3rd generation Xeon Scalable server processors based on the Sunny Cove microarchitecture. Ice Lake represents an Architecture step in Intel's Process-Architecture-Optimization model. Produced on the second generation of Intel's 10 nm process, 10 nm+, Ice Lake is Intel's second microarchitecture to be manufactured on the 10 nm process, following the limited launch of Cannon Lake in 2018. However, Intel altered their naming scheme in 2020 for the 10 nm process. In this new naming scheme, Ice Lake's manufacturing process is called simply 10 nm, without any appended pluses. Ice Lake CPUs are sold together with the 14 nm Comet Lake CPUs as Intel's "10th Generation Core" product family. There are no Ice Lake desktop or high-power mobile processors; Comet Lake fulfills this role. Sunny Cove-based Xeon Scalable CPUs (codenamed "Ice Lake-SP") officially launched on April 6, 2021 ...

SSE2
SSE2 (Streaming SIMD Extensions 2) is one of the Intel SIMD (Single Instruction, Multiple Data) processor supplementary instruction sets first introduced by Intel with the initial version of the Pentium 4 in 2000. It extends the earlier Streaming SIMD Extensions, SSE instruction set, and is intended to fully replace MMX (instruction set), MMX. Intel extended SSE2 to create SSE3 in 2004. SSE2 added 144 new instructions to SSE, which has 70 instructions. Competing chip-maker AMD added support for SSE2 with the introduction of their Opteron and Athlon 64 ranges of x86-64, AMD64 64-bit CPUs in 2003. Features Most of the SSE2 instructions implement the integer vector operations also found in MMX. Instead of the MMX registers they use the XMM registers, which are wider and allow for significant performance improvements in specialized applications. Another advantage of replacing MMX with SSE2 is avoiding the mode switching penalty for issuing x87 instructions present in MMX because it i ...

Intel Core
Intel Core is a line of streamlined midrange consumer, workstation and enthusiast computer central processing units (CPUs) marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets. The lineup of Core processors includes the Intel Core i3, Intel Core i5, Intel Core i7, and Intel Core i9, along with the X-series of Intel Core CPUs. Outline Although Intel Core is a brand that promises no internal consistency or continuity, the processors within this family have been, for the most part, broadly similar. The first products receiving this designation were the Core Solo and Core Duo Yonah processors for mobile from the Pentium M design tree, fabricated at 65 nm and brought to market in January 2006. These are substantially diffe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Semiconductor Device Fabrication
Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuit (IC) chips such as modern computer processors, microcontrollers, and memory chips such as NAND flash and DRAM that are present in everyday electrical and electronics, electronic devices. It is a multiple-step sequence of Photolithography, photolithographic and chemical processing steps (such as surface passivation, thermal oxidation, planar process, planar diffusion and p–n junction isolation, junction isolation) during which electronic circuits are gradually created on a wafer (electronics), wafer made of pure semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications. The entire manufacturing process takes time, from start to packaged chips ready for shipment, at least six to eight weeks (tape-out only, not including the circuit design) and is performed in highly specialized semiconduct ...

Microarchitecture
In computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as µarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor. A given ISA may be implemented with different microarchitectures; implementations may vary due to different goals of a given design or due to shifts in technology. Computer architecture is the combination of microarchitecture and instruction set architecture. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the instructions, execution model, processor registers, address and data formats among other things. The microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detai ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Intel Codenames
Intel has historically named integrated circuit (IC) development projects after geographical names of towns, rivers or mountains near the location of the Intel facility responsible for the IC. Many of these are in the American West, particularly in Oregon (where most of Intel's CPU projects are designed; see Project code name#Famous code names, famous codenames). As Intel's development activities have expanded, this nomenclature has expanded to Israel and India, and some older codenames refer to celestial bodies. The following table lists known Intel codenames along with a brief explanation of their meaning and their likely namesake, and the year of their earliest known public appearance. Most processors after a certain date were named after cities that could be found on a map of the United States. This was done for trademark considerations. Banias was the last of the non-US city names. Gesher was renamed to Sandy Bridge to comply with the new rule. Dothan is a city both in Israel ...

Intel VT-d
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance. In 2005 and 2006, both Intel (VT-x) and AMD ( AMD-V) introduced limited hardware virtualization support that allowed simpler virtualization software but offered very few speed benefits. Greater hardware support, which allowed substantial speed improvements, came with later processor models. Software-based virtualization The following discussion focuses only on virtualization of the x86 architecture protected mode. In protected mode the operating system kernel runs at a higher privilege such as ring 0, and applications at a lower privilege such as ring 3. In software-based virtualization, a host OS has direct access to hardware while the guest OSs have limited ac ...

FMA Instruction Set
The FMA instruction set is an extension to the 128 and 256-bit Streaming SIMD Extensions instructions in the x86 microprocessor instruction set to perform fused multiply–add (FMA) operations."FMA3 and FMA4 are not instruction sets, they are individual instructions -- fused multiply add. They could be quite useful depending on how Intel and AMD implement them" There are two variants: * FMA4 is supported in AMD processors starting with the Bulldozer architecture. FMA4 was performed in hardware before FMA3 was. Support for FMA4 has been removed since Zen 1. * FMA3 is supported in AMD processors starting with the Piledriver architecture and Intel starting with Haswell processors and Broadwell processors since 2014. Instructions FMA3 and FMA4 instructions have almost identical functionality, but are not compatible. Both contain fused multiply–add (FMA) instructions for floating-point scalar and SIMD operations, but FMA3 instructions have three operands, while FMA4 ones have ...

AVX-512
AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture (ISA) proposed by Intel in July 2013, and implemented in Intel's Xeon Phi x200 (Knights Landing) and Skylake-X CPUs; this includes the Core-X series (excluding the Core i5-7640X and Core i7-7740X), as well as the new Xeon Scalable Processor Family and Xeon D-2100 Embedded Series. AVX-512 consists of multiple extensions that may be implemented independently. This policy is a departure from the historical requirement of implementing the entire instruction block. Only the core extension AVX-512F (AVX-512 Foundation) is required by all AVX-512 implementations. Besides widening most 256-bit instructions, the extensions introduce various new operations, such as new data conversions, scatter operations, and permutations. The number of AVX registers is increased from 16 to 32, and eight new "mask registers" are added, which allow for variable selection and blendi ...
