AI Technical Summary

Problems solved by technology

As the system has higher and higher requirements for processing performance and external interfaces, the data processing of various complex external interfaces takes up more PowerPC processing time and affects the real-time performance of the entire system. Therefore, relying solely on PowerPC processors to achieve data processing and Interface processing can no longer meet the demand
