As an embedded motherboard customization service provider, Langruizhike believes that at present, ARM motherboards use Windows CE system or Linux system. Therefore, for many customers, the X86 platform was originally used. The software platform must be recompiled and adjusted, and the working mechanism of the ARM embedded platform must be familiarized, so the development workload in the early stage will be increased.
Advantage comparison:
(1) Performance: At present, the performance of ARM motherboards is getting closer and closer to X86 motherboards, and even surpasses it in some aspects. It is similar to X86 in several aspects such as video multimedia and data communication.
(2) Fever: The ARM motherboard does not heat up, and the temperature of the motherboard is generally room temperature, so it can be turned on and work online for many years without any problems. The X86 motherboard CPU must be equipped with a fan and cannot work for a long time, otherwise the temperature generated by the motherboard will reduce the overall performance and life of the motherboard. The working life of the fan will also affect the life of the motherboard.
(3) Boot time: The boot speed of the ARM motherboard is very fast, generally only a few seconds, and the X86 needs to be booted for a period of time before the Windows system will start up.
4) Power consumption: This is one of the biggest advantages of ARM motherboards. The power consumption of general VIA X86 motherboards is about 40W or more, while the power consumption of ARM motherboards is extremely low, such as micro-embedded industrial tablet computers ( Using ARM architecture), when the backlight is turned off, the overall power consumption of the motherboard is only about 1W.
(5) Working time and environment: The ARM motherboard is not limited by time, it can always be turned on and work without personnel to maintain, and in the case of power regulation, as long as there is a call, it will automatically start, no need for personnel to start or shut down, and The X86 motherboard needs to be maintained by personnel, and it cannot work for a long time, otherwise the life of the motherboard will be greatly reduced.
Environment: ARM motherboards are generally industrial poles and are not affected by the environment. The lowest temperature can be around -20 degrees Celsius, and the highest temperature can be around 70 degrees Celsius, but X86 is generally not good.
(6) Data security: ARM motherboards are highly integrated, and the data is generally placed inside the Flash, which is in binary format, and the internal data cannot be directly copied from the outside. And the biggest advantage is: the current ARM motherboard system is WinCE system or Linux system, which will not be infected by virus, customers do not need to worry about data leakage caused by virus infection, especially in some places with high data security requirements. ARM motherboards are very suitable, but X86 is just the opposite. Because they all use common systems such as Windows XP and 2000, and use DOM disks or hard disks, data is easily infected by viruses or stolen, so the security cannot be compared.
(7) Motherboard security: The memory and all chips of the ARM motherboard are patched, so they will not loosen when the surrounding environment vibrates, while the X86 adopts the in-line method, such as memory sticks and DOM disks, etc. , so once the time is long, there will be looseness and affect the operation of the system.
(8) Price: The current price of ARM motherboards is very low, and ARM motherboards already contain memory and storage media, so there is no need to purchase external accessories, so the overall system cost is much lower than the price of X86.
(9) Flexibility: ARM motherboards can be flexibly configured according to the needs of users, such as logo, memory size, system driver cutting, cutting of surrounding chips, loading of system software, etc., both software and hardware are very flexible. It will also greatly reduce customer costs and overall system maintenance costs and performance, which X86 cannot do. Micro-embedded WinCE industrial panel PC can be fully configured according to user needs.
Summary: After reading the above information, what motherboard do you think is better? In general, I think the arm development board is more cost-effective.
