An Inter-subsystem Data Transfer Mechanism Based on a New Computer Architecture with Single CPU and Dual Bus

Focusing on the architecture characteristics of the new computer architecture with high-security sCPU-dBUS, this paper designs and implements an inter-subsystem data transfer mechanism based on the new high-security operating system with internal networking structure netOS-I which is only used by the sCPU-dBUS. The data transfer mechanism mainly contains inter-subsystem data transfer interface, inter-subsystem data transfer protocol and operation and management of transit cache memory.
