Competition between am335x and Quanzhi a40i

      That said , What is the comparability of the two chips ? It turns out that there is no comparability , However, at any time, the United States will chip China "k Neck ", Then the chip has comparability , Let me come together !

First say AM335X:

      AM335X yes TI（ TI ） be based on  ARM Cortex-A8 Kernel AM335X Microprocessor in image 、 Graph processing 、 Peripherals and devices such as EtherCAT and PROFIBUS Has been enhanced in terms of industrial interface options .

AM335X Its advantages are as follows ：

First of all ： The device is the cheapest Cortex A8 Processing chip , This is crucial to the Chinese market , Even the decisive factor .

second ：TI A chip with the most complete public information in history .

Third ： The most clear product positioning , Industrial control MCU

Fourth ： The only integration 2 individual MAC Of MCU.

The fifth ： Support 3 An operating system Linux,Android,WinCE. In addition, it supports third-party real-time operating systems such as QNX、VxWorks Such as system .AM335X The development board has been used in industrial control 、 Medical electronics 、 Energy conservation and environmental protection 、 Intelligent Transportation 、 Energy conservation 、 Electric power system 、 Communication system 、 Textile industry 、 CNC industry 、 Automotive electronics 、 Industrial touch screen control system 、 Robot vision 、 Media processing wireless applications 、 Digital appliances 、 Vehicle mounted equipment 、 Communication equipment 、 Network terminal It is widely used in harsh environment .AM335X Series include AM3352 processor 、AM3354、AM3356、AM3357、AM3358、AM3359, They can all work up to 1Ghz The speed of .

      If you want to do something with this chip , There is a lot of information , There are many boards , The most famous is bealgebone/beaglebone black, abbreviation bbb.Bbb It is with interface piece , It is still difficult to use it directly , Yingpengfei embedded system solves this problem , stay 2015 Compatible... Was introduced in bbb Of CoM-335X, It is said that there are several versions .

 

Besides, this Full ambition A40I/T3:

         Full ambition A40i The processor represents Allwinner The latest achievements in the field of intelligent industrial control . The processor is suitable for the need for 3D graphics 、 Advanced video processing applications . Rich user interfaces 、 High quality 、 Low power consumption 、 The system is highly integrated .

A40i It is mainly used in industrial control products based on visual interaction .

A40i Chip characteristics ：

Can support MIPI DSI Monitor 、RGB Panel or dual channel LVDS Display content on the panel . Also support CVBS-OUT and HDMIV1.4;

Support double cmos Sensor parallel interface and 4 passageway cvbs-in, Capable of performing multi-channel video recording .

A40I Meet industrial standards , The operating temperature reaches AEC-Q100 Class standards .

Integrated audio codec ,24 position /192 KHz DAC The playback , Support I2S/PCM Interface to external audio codec . Ions up to 32 position /192kHz.

In order to reduce the total system cost ,A40I It has extensive hardware peripheral support , Support configuration of arrays , for example 3*USB2.0、GMAC/EMAC( Dual network )、8*UART( At most )、SATA、2*TSC、PS2、RTP、4*SDHC etc. , Support Linux3.10、Android7.1 And the system above .

From the above we can sum up a few points :

    The two will have application intersection in certain occasions , such as : Both have display interfaces , and A40I The display interface of is more abundant ,A40I The only drawback is , He didn't ETHERCAT, So I can't get involved in professional The scene Control area . in addition AM335X It has two Gigabit MAC, At the same time, the bit switch can be configured to use , and A40I/T3 All the way Gigabit MAC And 100M MAC, The two routes are independent , It can realize two independent networks , But it cannot be used as a switch .A40I There are also his highlights , It's a quad core processor , It is also faster AM335X Faster , It can also support up to 1920X1080P Video playback of , In the advertisement * field ,A40I/T3 More suitable . It's not hard to find out , The realization of human-computer interface is their intersection . Chips are the blood of industry , We have to consider alternatives ！ Especially in the near future ,TI There is a problem with the supply of semiconductors ,

The product cost is high , What should I do ？

As far as I know , Yingpengfei embedded At present, it is available in bulk A40I/T3 Core module 了 , At the same time, yingpengfei embedded also provides PREEMPT LINUX System , Yingpengfei embedded provides A40I/T3 The model number is CoM-X40I, Size and their company's CoM-335x It's the same , Very convenient for users to replace .
