Cortex-A 15 can provide the highest performance solution for the next generation of mobile infrastructure applications and demanding wireless infrastructure applications. Cortex-A7 can be implemented in a standalone multi-core configuration, providing a typical frequency of 800 MHz- 1.2 GHz. It can also be used in combination with Cortex-A 15 to implement big in Cortex-A9. Small processing, can provide the standard frequency of 800 MHz-2 GHz, and each core can provide the performance of 5000 DMIPS. Cortex-A8 single-core solution can provide cost-effective high performance. At the frequency of 600 MHz- 1 GHz, the performance provided by Cortex-A5 is greater than 2000 dmips, and at the frequency of 400- 800 MHz, the performance provided by Cortex-A5 is greater than 1200 DMIPS. Cortex-A5, Cortex-A7, Cortex-A9 and Cortex-A 15 processors all support ARM's second-generation multi-core technology.
Single-core to quad-core implementation supports performance-oriented applications, symmetric and asymmetric operating systems, and the whole processor exported to the system through the accelerator coherency port (ACP) maintains consistency. Cortex-A7 and Cortex-A 15 extend the multi-core consistency to the 1~4 core cluster of AMBA4 ACE (AMBA consistency extension), except that they have the same characteristics as the previous generation classic ARM and Thumb &; Reg In addition to the binary compatibility of the architecture, Cortex-A processor provides more advantages through the following technical extensions.
Thumb-2 is a TrustZone security extension with the best code size and performance, which provides Jazelle technology for trusted computing and improves the execution environment (such as Java,. Net, MSIL, Python and Perl).
