AI Technical Summary

Problems solved by technology

[0007] It can be seen from the above that the mobile terminal baseband SOC with multi-core architecture requires a large number of hardware devices and special hardware devices, the system is complex, and the design availability is not high.

If the standard changes, or the market demand changes, or the system is upgraded, the designer has to redesign new hardware to replace the original hardware. The cost is high and the research and development cycle is long, which is not conducive to adapting to market changes and upgrading optimization.
