The two Modems share a CPU (mobile phone processor), and the CPU processes the data in the mobile phone memory (RAM) and the mobile phone memory (EMMC), thereby interacting with the external device to control the peripheral (external device).

The drawbacks of existing solutions are:

1. The traditional dual standby architecture runs dual systems, using Trustzone technology to physically isolate the CPU layer to provide a secure execution environment for encrypted data. The actual situation shows that: the traditional dual standby architecture two modems share a CPU, all data including voice service data, data service data and other data are processed by the CPU. With the rapid development of the smart machine, the amount of data in the smart machine is very Huge, a CPU will cause the data processing speed to be significantly slower, affecting the user experience;

2. Although physical isolation is performed in the CPU layer, all data is processed by one CPU, the data is easily confused, and the security and privacy of important data such as telephone contacts, short messages, security passwords, and bank accounts are not effectively protected. And can not achieve independent security in the true sense;

3. The traditional intelligent machine only has one RAM and EMMC to process huge data. When the amount of data increases sharply, it seriously affects the stability of RAM and EMMC. All the data mixed together will also affect the security of personal private data; according to experience, RAM and EMCC Data confusion can easily cause the phone to crash, affecting the security of personal data.
