Deep understanding of ARM's strongest 64-bit processor ARMv8 architecture is amazing?

ARMv8 is a true 64-bit device, and 32-bit support has been added or provided for this 64-bit architecture.

The Cortex-A57 is ARM's most advanced and highest performance application processor, and the Cortex-A53 is not only the most power efficient ARM application processor, but also the world's smallest 64-bit processor. The two processors can operate independently or integrated into the ARM big.LITTLE processor architecture to combine high performance with high power efficiency. ARM's CoreLink 400 and CoreLink 500 Series system IP architecture solutions also support both processors.

The ARMv8 series is the first 64-bit series in ARM history. The Cortex-A 57 provides the latest performance for smartphone and super mobile phone power consumption. The super mobile phone refers to Samsung's Glaxay3 or Apple's iPhone5 mobile phone. Mobile phone, Cortex-A57 in the past development process code is Atlas. The Cortex-A53 is the most power-efficient application processor ever developed by ARM. It is also a good application for the big.LITTLE mentioned earlier. The Cortex-A53 is code-named Apollo during development.

Optimized for high performance, the Cortex-A57 delivers maximum performance while running on smartphones, and drives advanced computing with up to five times more power efficiency, optimized software and security architecture. The application gets a higher boost. Some people may ask what it means for the enterprise. This allows the Cortex-A57 to provide full 64-bit support for the enterprise, and users can choose four, eight or sixteen cores according to their choice. High performance while maintaining power consumption at a very low level.

The Cortex-A53 is probably comparable in performance to the familiar Cortex-A9, which is the most popular processor for mainstream smartphones, but it's much smaller. It can reduce the size by 40% in the 32nm process. If it is 20nm, it may only be the size of the current mainstream CPU1/4. So A53 may be a good choice for such a smart phone with low power consumption. But at the same time, more and more enterprise-level applications can be attracted by the low-power features of the A53. In the future, we will see many data centers may rethink the choice of enterprise-type processors.

In the figure below, you can see two lines. The blue line above represents the evolution of the ARM product roadmap. The ARM processor brings higher and higher performance. The green line below represents it. Power consumption. You can see that the birth of the left-most Cortex-A8 redefines the performance represented by the ARM processor. Gradually, the more mainstream dual-core Cortex-A9 and the quad-core that have just been launched by some ARM partners. The Cortex-A9 has achieved very high performance, but basically remains at the same power level. With the launch of the Cortex-A50 today, you will see the development of dual-core A53 and 57, official delivery will be in 2014.

The Cortex-A50 series is actually very scalable, ranging from smartphones to super phones and tablets to mobile computers to servers. In the future, they can meet different requirements for different configurations of the A53 and A57. So the A50 series reflects flexibility and scalability.

The release of the two processors A53 and A57 in the Cortex-A50 series may be the most important product release since the 25th anniversary of ARM, which is the first 64-bit product that will change whether it is mobile computing or The server, or the future market of the network, will work with more partners to provide the best experience for our customers and ARM users.

ARM organization chart (from ARM official website)

The new 64-bit processor is a milestone on the road for ARM. I believe everyone has seen some ARM partners have announced the use of ARM technology to develop some chips for network applications, and now see in the future It is possible that in this area, with the launch of new products, they will be able to move to a new market like 64-bit. The demand for the new 64-bit processor family exceeds any previous ARM chip product. I believe this will not happen overnight, but in the future ARM can use such products to meet some applications in specific areas and specific needs.

ARM wants to give you a very important concept, that is, no one size processor is suitable for all applications, so how to meet these different products in the future will bring a lot of software design and hardware design challenges. ARM also believes that through the innovation and joint efforts of ARM's partners, these products can be brought to market with some innovative ideas, and we hope to enjoy the latest ARM technology in a very short time.
