Exynos
Exynos, formerly Hummingbird (), is a series of ARM-based system-on-chips developed by Samsung Electronics' System LSI division and manufactured by Samsung Foundry. It is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs. Exynos is mostly based on the ARM Cortex cores with the exception of some high end SoCs which featured Samsung's proprietary "M" series core design; though from 2021 onwards even the flagship high-end SoC's will be featuring ARM Cortex cores. History In 2010, Samsung launched the Hummingbird S5PC110 (now Exynos 3 Single) in its Samsung Galaxy S smartphone, which featured a licensed ARM Cortex-A8 CPU. This ARM Cortex-A8 was code-named Hummingbird. It was developed in partnership with Intrinsity using their FastCore and Fast14 technology. In early 2011, Samsung first launched the Exynos 4210 SoC in its Samsung Galaxy S II mobile smartphone. The driver code for the Exynos 4210 was made available in the Linux kernel and support was ...

Thumb-2
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer (RISC) instruction set architectures for computer processors, configured for various environments. Arm Ltd. develops the architectures and licenses them to other companies, who design their own products that implement one or more of those architectures, including system on a chip (SoC) and system on module (SOM) designs, that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement these instruction set architectures and licenses these designs to many companies that incorporate those core designs into their own products. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a 26-bit address space that limited it to 64 MB of main memory. This limitation was removed in the ARMv3 series, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ARM Holdings
Arm is a British semiconductor and software design company based in Cambridge, England. Its primary business is in the design of ARM processors (CPUs). It also designs other chips, provides software development tools under the DS-5, RealView and Keil brands, and provides systems and platforms, system-on-a-chip (SoC) infrastructure and software. As a "holding" company, it also holds shares of other companies. Since 2016, it has been owned by Japanese conglomerate SoftBank Group. While ARM CPUs first appeared in the Acorn Archimedes, a desktop computer, today's systems include mostly embedded systems, including ARM CPUs used in virtually all smartphones. Systems such as iPhones and Android smartphones frequently include many chips, from many different providers, that include one or more licensed Arm cores, in addition to those in the main Arm-based processor. Arm's core designs are also used in chips that support all the most common network-related technologies. Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NeuroMatrix
NeuroMatrix is a digital signal processor (DSP) series developed by NTC Module. The DSP has a VLIW/SIMD architecture. It consists of a 32-bit RISC core and a 64-bit vector co-processor. The vector co-processor supports vector operations with elements of variable bit length (US Pat. 6539368 B1) and is optimized to support the implementation of artificial neural networks. From this derives the name NeuroMatrix Core (NMC). Newer devices contain multiple DSP cores and additional ARM or PowerPC 470 cores.

AT91SAM
Atmel ARM-based processors are microcontrollers and microprocessors integrated circuits, by Microchip Technology (previously Atmel), that are based on various 32-bit ARM processor cores, with in-house designed peripherals and tool support. Overview ARM licenses the core design for a series of 32-bit processors. ARM does not manufacture any complete silicon products, just intellectual property (IP). The ARM processors are RISC (reduced instruction set computing). This is similar to Microchip’s AVR 8-bit products, a later adoption of RISC architecture. Whereas the AVR architecture used Harvard architecture exclusively, some ARM cores are Harvard (Cortex-M3) and others are Von Neumann architecture (ARM7TDMI). Semiconductor companies such as Microchip take the ARM cores, which use a consistent set of instructions and register naming, and add peripheral circuits such as ADCs (analog to digital converters), clock management, and serial communications such as USART, SPI, I2C, CAN, L ...

Out-of-order Execution
In computer engineering, out-of-order execution (or more formally dynamic execution) is a paradigm used in most high-performance central processing units to make use of instruction cycles that would otherwise be wasted. In this paradigm, a processor executes instructions in an order governed by the availability of input data and execution units, rather than by their original order in a program. In doing so, the processor can avoid being idle while waiting for the preceding instruction to complete and can, in the meantime, process the next instructions that are able to run immediately and independently. History Out-of-order execution is a restricted form of data flow computation, which was a major research area in computer architecture in the 1970s and early 1980s. The first machine to use out-of-order execution was the CDC 6600 (1964), designed by James E. Thornton, which uses a scoreboard to avoid conflicts. It permits an instruction to execute if its source operand (read ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
