A Queued Serial Peripheral Interface (QSPI; different to but has same abbreviation as Quad SPI described in § Quad SPI) is a type of SPI controller that uses a data queue to transfer data across an SPI bus. [19] It has a wrap-around mode allowing continuous transfers to and from the queue with only intermittent attention from the CPU.
The Intel QuickPath Interconnect (QPI) [1] [2] is a scalable processor interconnect developed by Intel which replaced the front-side bus (FSB) in Xeon, Itanium, and certain desktop platforms starting in 2008. It increased the scalability and available bandwidth.
The System Packet Interface (SPI) family of Interoperability Agreements from the Optical Internetworking Forum specify chip-to-chip, channelized, packet interfaces commonly used in synchronous optical networking and Ethernet applications. A typical application of such a packet level interface is between a framer (for optical network) or a MAC ...
In contrast, Uncore functions include QPI controllers, L3 cache, snoop agent pipeline, on-die memory controller, on-die PCI Express Root Complex, and Thunderbolt controller. [3] Other bus controllers such as SPI and LPC are part of the chipset. [4] The Intel uncore design stems from its origin as the northbridge. The design of the Intel uncore ...
TSX instructions are disabled in this series of processors because a bug that cannot be fixed with a microcode update exists. [11] Broadwell-U: SoC; two TDP classes – 15 W for 2+2 and 2+3 configurations (two cores with a GT2 or GT3 GPU) as well as 28 W for 2+3 configurations. [12]
SSE4 (Streaming SIMD Extensions 4) is a SIMD CPU instruction set used in the Intel Core microarchitecture and AMD K10 (K8L).It was announced on September 27, 2006, at the Fall 2006 Intel Developer Forum, with vague details in a white paper; [1] more precise details of 47 instructions became available at the Spring 2007 Intel Developer Forum in Beijing, in the presentation. [2]
Unlike the front-side bus (FSB), QPI is a point-to-point interface and supports not only processor-chipset interface, but also processor-to-processor connection and chip-to-chip connection. The X58 has two QPIs and can directly connect to two processors on a multi-socket motherboard or form a ring-like connection (processor 1 to X58 to ...
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
