The ARM Cortex- A9 is a series of processors based on the instruction set ARMv7. Many mainstream processor applications need higher performance to achieve faster data rates, more media services and more new functions (such as encryption and security using rich dynamic user interfaces).
In this kind of application, consumer demand is the main driving force to promote product development, so reducing the cost of end products has become a major challenge for manufacturers. This is not just a question of competition: it is also a question of opening up new markets in developing countries, whose disposable income is far lower than that in the western world.
Extended data
Cor tex-A9 processor has unparalleled performance and efficacy, and it is undoubtedly an ideal solution for low-power and cost-sensitive devices based on single-core processors, which need high performance.
The processor-level design of ARM M11T M not only requires improving performance and efficiency without increasing chip cost and power consumption, but also requires maintaining a highly compatible software environment. Therefore, Cortex-A9 processor adopts convenient integrated IP delivery, which provides an ideal upgrade channel for existing ARM 1 1TM.
The C o r t e x-A9 single-core processor provides two low-latency Harvard 64-Bitamba &;; Reg3aximmaster interface, when copying data through memory buffer, can maintain 4 double-word writes every 5 processor cycles.
Cor tex-A9 processor provides scalable solutions for various market applications, including mobile phones, high-end consumer electronics and enterprise products, because it meets the following requirements:
1, reducing power consumption and improving efficiency and performance;
2. Improve peak performance and adapt to the most demanding applications;
3. Software and tools that can be reused when developing different devices;
4. Both Cortex-A9 processors have perfect application compatibility. By using Cortex-A9 neon;
5. The media processing engine (MPE) or floating-point arithmetic unit (FPU) can also enhance the performance in specific applications, and further expand the market application scope of these two processors.
