It is not exaggerated that Cortex-A15 is a processor that has so far performance in the ARM 32-bit processor. It is basically only able to see its figure on the flagship phone or tablet, and for the development board, If you want to carry the Cortex-A15 processor, it is a bit too expensive, just as the mainstream open source hardware platform, the Raspberry Part 2, banana panel, etc., basically in low power, high-performance ARM Cortex-A7 is host. Of course, we don't rule out the exception. As recently, the pavilion has got a performance powerful open source hardware board Cubieboard4, completely breaking this "rule" - equipped with the general UltraOcta A80 eight-core SOC (Cortex-A15 * 4 + Cortex-A7 * 4) direct high-end open source hardware market.
CubieBoard4 hardware introduction
CubieBoard4, also known as "CC-A80", a high-performance development platform, which is launched by Furnish sugar electronics, I believe that many hardware enthusiasts are not strange to this company, which may have already contacted this company CubieBoard1 / 2 before this / 3 A few generations of products, of course, CubieBoard4 is obvious than the previous generation of products, and the performance improvement is obvious. Let's first come together.
"Rough" packaging, positive printed with CC-A80 characters, very conspicuously highlighting the focus of board, A80 application processor.
The A80's performance is powerful, and the Cubieboard 4 has a wide range of features. In order to release the functionality of the board, the power supply is equipped with a 5V / 4A output power adapter, which is still less in the open source hardware board.
Open the Cubieboard 4 box, the big and small accessories are really a "dazzling full", overall, Cubieboard 4's accessories mainly include:
Cubieboard4 CC-a80 x1
Acrylic housing x1
RTC battery x1
40 * 10 * 10 heat sink X1
5G / 2.4G dual frequency antenna X1
USB OTG line TYPE A Motherlet Micro 3.0 Gloduck X1
USB data line Type A Glutter Transfer Micro 3.0 公口 x1
Conductive silicon x1
Screw bag x1
The heat-insulating silicon and heat sink from the fitting can see that the main control of the board is still very large. The maximum frequency of the highest frequency may require support for heat dissipation conditions, but special intimate is Cubieboard4 provides an acrylic housing, allowing engineers to do not have to endure The impulse of the bare plate. The layout of the CubieBoard4 has a substantially a medium in the front, and there is only one 8GB of EMMC storage on the back. Refer to the following figure, we will see the board resources of CubieBoard4.
CubieBoard4 onboard resources:
Total A80 SOC, CPU: ARM Cortex A15X4 UP TO 2.0GHz, A7X4 UP TO 1.3GHz; GPU: PowerVR 64-Core G6230
2GB DDR3 memory, 8GB EMMC Flash memory
USB 2.0 X4, USB 3.0 OTG
Onboard RTC battery, TF card slot, power button, infrared receiving head, microphone input interface, headphone output interface
WiFi + BT, reset button, LED light X2, external antenna interface, brush button
VGA interface, Gigabit Ethernet, HDMI interface, power interface, lithium battery interface, extended IO port
For the peripheral of the development board, the CubieBoard4 is equipped with VGA and HDMI interface in video output, and the author is unexpected, the card is actually equipped with the OTG interface of USB3.0, as shown in the details of the following.
Obviously, the Cubieboard 4 is equipped with a rich audio and video output function to make the board of entertainment, such as home theater, games, HD tip boxes, etc. (Next)
MCU development board recommended:
STM32 F4 Getting Started Suite A STM32 F4 Series ARM Cortex-M4 kernel's microcontroller is complete and cost-effective development board.
MB9BF524K Getting Started Suite A low-cost evaluation board based on spansion FM3 microcontroller MB9B520M series.
LPC4088 Evaluation Board A development board that requires advanced communication and high quality graphic display based on NXP Cortex-M4 LPC4088 microcontroller.
Of course, we are most curious or have the performance monsters of the cubieboard4 Monster A80 SOC? From the basic information, the full-state A80 uses a 28 nm HPM process with a size of 19mm * 19mm, FCBGA636 Balls encapsulation, using 4 core Cortex-A15 and 4 core Cortex-A7 BIG.LTIILE architecture, as shown below.
From the A80 SOC brief system block diagram, we are not difficult to find that A80 has a high-performance processor internally integrated eight-core, but also integrates the 64-core high-performance PowerVR G6230 GPU, supports H.265 format, 4K resolution coding, decoding, Support for three-screen output, in addition to this, A80 also integrates rich resources, especially with multimedia's resources, equipped with rich display interfaces, such as HDMI, LCD RGB, MIPI DSI, LVDS, etc., also equipped Image input interface, including CSI and MIPI CSI, etc., we can still see that the A80 side focus is in multimedia handling this domain compared to other peripheral interface resources.
Of course, this does not mean that the A80 is poor in other respects. On the contrary, A80 is absolutely an excellent application handling SOC in a single board computer evaluated by the panel network. In this way, it is said that you have no impression, we look at other board computers in the current market, for example, the newly fireful banana sent, and it is also equipped with all the best to process SOC A20, this Compared with both, we can see the advantages of A80:
First, the performance of the CPU is upgraded from 2 core A7 to 4 core A7 + 4 core A15
Second, GPU upgrade, upgrade to 64 core PowerVR G6230 GPU
Of course, in addition to the superior performance, A80 has a lot of functions, from the globbessing of the entire board, there is not much chip, but the board's peripheral resources are very rich, mainly in the A80 application processor. Ultra high integration can support so many features, from the overall application direction, A80 is a high-performance flat-board solution for the entire market.
Sink installation
Cubieboard 4 provides us with a complete set of accessories. If you don't use it, you are quaint, after you understand the performance and functionality of CubieBoard4, we will assemble the Yarik box, but before this, we must first for Cubieboard 4. Install the heat sink, as shown in the figure below, first apply the thermal silicon in the fitting on the A80 SOC.
The heat sink is then fixed, and the spring buckle can be fixed by the spring sides of the corner.
Install the heat sink, then put the acrylic housing, the whole Cubieboard 4 looks very eye-catching, how can a cool word.
After the assembly is completed, we can power on the board. Connect the required peripherals to the development board, such as HDMI output, mouse keyboard, etc., aspect can be freely operated, and we will follow the system experience of CubieBoard4. For details, please look forward to it.
summary
Introduced the super performance open source board CUBIEBOARD4 launched by Furnish Sugar Technology, onboard full-time, based on 4 core Cortex-A15 + 4 core Cortex-A7, performance is far from the forefront of the current open source hardware board, even if it is Compared with Fangtue Electronics, the performance is far ahead than the CubieBoard1 / 2/3. In addition to the powerful performance, CubieBoard4 is equipped with rich features, a variety of peripheral interfaces, such as HDMI output, VGA video output, Gigabit Ethernet, board of wireless modules, and wireless modules of WiFi + BT, aspect users DIY wireless intelligent hardware products, In addition, in the official website of Cubieboard, there is a wealth of information, familiar with the user, developing Cubieboard4, providing the necessary guarantees, interested friends can go to Fuganda Electronic Official website to buy.
