Cortex-A7
The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011. Overview It has two target applications; firstly as a smaller, simpler, and more power-efficient successor to the Cortex-A8. The other use is in the big.LITTLE architecture, combining one or more A7 cores with one or more Cortex-A15 cores into a heterogeneous system. To do this it is fully feature-compatible with the A15. Key features of the Cortex-A7 core are: * Partial dual-issue, in-order microarchitecture with an 8-stage pipeline * NEON SIMD instruction set extension * VFPv4 Floating Point Unit * Thumb-2 instruction set encoding * Jazelle RCT * Hardware virtualization * Large Page Address Extensions (LPAE) * Integrated level 2 Cache (0–1 MB) * 1.9 DMIPS / MHz * Typical clock speed 1.5 GHz Chips Several system-on-chips (SoC) have implemented the Cortex-A7 core, including: * Allwinner A20 (dual-core A7 + Mali-400 MP2 GPU) * ...

Raspberry Pi
Raspberry Pi ( ) is a series of small single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in collaboration with Broadcom Inc., Broadcom. To commercialize the product and support its growing demand, the Foundation established a commercial entity, Raspberry Pi Holdings, a public company that trades on the London Stock Exchange. The Raspberry Pi was originally created to help teach computer science in schools, but gained popularity for many other uses due to its low cost, compact size, and flexibility. It is now used in areas such as Industrial Automation and Control Systems, industrial automation, robotics, home automation, IoT devices, and hobbyist projects. The company's products range from simple microcontrollers to computers that the company markets as being powerful enough to be used as a general purpose PC. Computers are built around a custom designed system on a chip and offer features such as HDMI video/audio output, USB ports, wi ...

VideoCore
VideoCore is a series of low-power mobile multimedia processors originally developed by Alphamosaic Ltd and now owned by Broadcom. Alphamosaic marketed its first version as a two-dimensional DSP architecture that makes it flexible and efficient enough to decode (as well as encode) a number of multimedia codecs in software while maintaining low power usage. The semiconductor intellectual property core (SIP core) has been found so far only on Broadcom SoCs. Technical details Multimedia system constraints Mobile multimedia devices require a lot of high-speed video processing but at low power for long battery life. The ARM processor core has a high IPS per watt figure (and thus dominates the mobile phone market) but requires video acceleration coprocessors and display controllers for a complete system. The amount of data passing between these chips at high speed results in higher power consumption. Specialised co-processors may be optimised for throughput over latency (mor ...
