Hierarchical bus system applied to real-time data processing

The invention discloses a hierarchical bus system, which comprises a real-time high-speed bus, a non-real-time high-speed bus, a non-real-time low-speed bus, a low-speed bus interconnection module, a high-speed bus interconnection module, a high-speed storage, an embedded processor, a real-time bus input/output module, a real-time bus data processing module, a non-real-time high-speed bus input/output module and a non-real-time low-speed bus input/output module. The real-time bus input/output module, the real-time bus data processing module and the high-speed storage are connected with the real-time high-speed bus through real-time high-speed bus interfaces; the embedded processor and the non-real-time high-speed bus input/output module are connected with the non-real-time high-speed bus through non-real-time high-speed bus interfaces; the non-real-time low-speed bus input/output module is connected with the non-real-time low-speed bus through a non-real-time low-speed bus interface; the non-real-time low-speed bus is connected with the non-real-time high-speed bus through the low-speed bus interconnection module; and the non-real-time high-speed bus is connected with the real-time high-speed bus through the high-speed bus interconnection module. By the aid of the hierarchical bus system, mega data can be efficiently transmitted and processed by the hierarchical bus system in real time, and bus bandwidth is effectively used.
