ARM Cortex-A53
The ARM Cortex-A53 is one of the first two central processing units implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Cambridge design centre, along with the Cortex-A57. The Cortex-A53 is a 2-wide decode superscalar processor, capable of dual-issuing some instructions. It was announced October 30, 2012 and is marketed by ARM as either a stand-alone, more energy-efficient alternative to the more powerful Cortex-A57 microarchitecture, or to be used alongside a more powerful microarchitecture in a big.LITTLE configuration. It is available as an IP core to licensees, like other ARM intellectual property and processor designs.

Amazon Echo Dot
Amazon Echo, often shortened to Echo, is a brand of smart speakers developed by Amazon. Echo devices connect to the voice-controlled intelligent personal assistant service. ''Alexa'', which responds to a wake term (''Alexa'', and others) when spoken by its user. The features of the device include voice interaction, audio program playback, such as music, streaming podcasts, and audiobooks, maintaining to-do lists, alarms, and scheduling reminders. in addition to providing weather, traffic and other real-time information. It can also control several smart devices, acting as a home automation hub. Amazon started developing Echo devices inside its Lab126 offices in Silicon Valley and in Cambridge, Massachusetts as early as 2010. The device represented one of its first attempts to expand its device portfolio beyond the Kindle e-reader. Amazon initially limited the first-generation Echo to Amazon Prime members or just by invitation, but it became widely available in the United State ...

VFP (instruction Set)
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses cores that implement these ISAs. Due to their low costs, low power consumption, and low heat generation, ARM processors are useful for light, portable, battery-powered devices, including smartphones, laptops, and tablet computers, as well as embedded systems. However, ARM processors are also used for desktops and servers, including Fugaku, the world's fastest supercomputer from 2020 to 2022. With over 230 billion ARM chips produced, , ARM is the most widely used family of instruction set architectures. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kryo
Qualcomm Kryo is a series of custom or semi-custom ARM-based CPUs included in the Snapdragon line of SoCs. These CPUs implement the ARM 64-bit instruction set and serve as the successor to the previous 32-bit Krait CPUs. It was first introduced in the Snapdragon 820 (2015). In 2017 Qualcomm released the Snapdragon 636 and Snapdragon 660, the first mid-range Kryo SoCs. In 2018 the first entry-level SoC with Kryo architecture, the Snapdragon 632, was released. Kryo (original) First announced in September 2015 and used in the Snapdragon 820 SoC. The original Kryo cores can be used in both parts of the big.LITTLE configuration, where two dual-core clusters (in the case of Snapdragon 820 and 821) run at different clock frequency, similar to how both Cortex-A53 clusters work in the Snapdragon 615. The Kryo in the 820/821 is an in-house custom ARMv8.0-A (AArch64/AArch32) design and not based on an ARM Cortex design. * 820: 2x Kryo Performance @ 2.15 GHz + 2x Kryo Efficien ...

The group consists of numerous affiliated businesses, most of which operate under the Samsung brand, and is the largest (business conglomerate) in South Korea. Samsung has the world's List of most valuable brands, fifth-highest brand value. Founded in 1938 by Lee Byung-chul as a trading company, Samsung diversified into various sectors, including food processing, textiles, insurance, securities, and retail, over the next three decades. In the late 1960s, Samsung entered the electronics industry, followed by the construction and shipbuilding sectors in the mid-1970s—areas that would fuel its future growth. After Lee died in 1987, Samsung was divided into five business groups: Samsung Group, Shinsegae Group, CJ Group, Hansol Group, and JoongAng Ilbo, JoongAng Group. K ...

Qualcomm
Qualcomm Incorporated () is an American multinational corporation headquartered in San Diego, California, and Delaware General Corporation Law, incorporated in Delaware. It creates semiconductors, software and services related to wireless technology. It owns patents critical to the 5G, 4G, CDMA2000, TD-SCDMA and WCDMA mobile communications standards. Qualcomm was established in 1985 by Irwin M. Jacobs, Irwin Jacobs and six other co-founders. Its early research into CDMA wireless cell phone technology was funded by selling a two-way mobile digital satellite communications system known as Omnitracs. After a heated debate in the wireless industry, CDMA was adopted as a 2G standard in North America, with Qualcomm's patents incorporated. Afterwards, there was a series of legal disputes about pricing for licensing patents required by the standard. Over the years, Qualcomm has expanded into selling semiconductor products in a predominantly fabless manufacturing model. It also develope ...

System On A Chip
A system on a chip (SoC) is an integrated circuit that combines most or all key components of a computer or Electronics, electronic system onto a single microchip. Typically, an SoC includes a central processing unit (CPU) with computer memory, memory, input/output, and computer data storage#Secondary storage, data storage control functions, along with optional features like a graphics processing unit (GPU), Wi-Fi connectivity, and radio frequency processing. This high level of integration minimizes the need for separate, discrete components, thereby enhancing Performance per watt, power efficiency and simplifying device design. High-performance SoCs are often paired with dedicated memory, such as LPDDR, and flash storage chips, such as Universal Flash Storage, eUFS or eMMC, which may be stacked directly on top of the SoC in a Package on a package, package-on-package (PoP) configuration or placed nearby on the motherboard. Some SoCs also operate alongside specialized chips, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branch Predictor
In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g., an if–then–else structure) will go before this is known definitively. The purpose of the branch predictor is to improve the flow in the instruction pipeline. Branch predictors play a critical role in achieving high performance in many modern pipelined microprocessor architectures. Two-way branching is usually implemented with a conditional jump instruction. A conditional jump can either be "taken" and jump to a different place in program memory, or it can be "not taken" and continue execution immediately after the conditional jump. It is not known for certain whether a conditional jump will be taken or not taken until the condition has been calculated and the conditional jump has passed the execution stage in the instruction pipeline (see fig. 1). Without branch prediction, the processor would have to wait until the conditional jump instruction has passed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Translation Lookaside Buffer
A translation lookaside buffer (TLB) is a memory CPU cache, cache that stores the recent translations of virtual memory address to a physical memory Memory_address, location. It is used to reduce the time taken to access a user memory location. It can be called an address-translation cache. It is a part of the chip's Memory management unit, memory-management unit (MMU). A TLB may reside between the Central processing unit, CPU and the CPU cache, between CPU cache and the main memory or between the different levels of the multi-level cache. The majority of desktop, laptop, and server processors include one or more TLBs in the memory-management hardware, and it is nearly always present in any processor that uses Memory paging, paged or Memory segmentation, segmented virtual memory. The TLB is sometimes implemented as content-addressable memory (CAM). The CAM search key is the virtual address, and the search result is a physical address. If the requested address is present in the TLB ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
