It is the control center system of the whole mobile phone and the control center of the logic part. Microprocessor achieves control by running the software in the memory and calling the database in the memory.
Simply increasing the number of CPU cores does not mean that it can bring about a significant improvement in performance. If we want to make full use of the computing resources provided by multi-core CPU, we need to adjust the operating system and existing applications at the same time. Moreover, the improvement of application performance by multi-core CPU depends on the ability to run multiple programs or threads at the same time.
If we look at Amdal's law, we can find that if the program has sequential code, the return of performance improvement will be less and less.
Prospect of mobile phone cpu
Recently including Texas Instruments, Intel, etc. , CPU with clock frequency as high as 1GHz has been introduced. Following the launch of TG0 1 produced in Qualcomm, Qualcomm will also release QSD8650A chipset with a clock frequency of 1.3GHz. In the future, the clock frequency of CPU will be higher and higher, the compatibility and running ability will be stronger and stronger, and the supporting functions will be better.
The heads of Qualcomm, TI and ARM all publicly stated that the potential of mobile phone CPU will be greater than that of PC in the future, and the simple dual-core can't meet the functions of mobile phones, only higher and stronger can meet the needs of all mobile phone users.
