HIERARCHICAL MULTI-CORE PROCESSOR, MULTI-CORE PROCESSOR SYSTEM, AND CONTROL PROGRAM

摘要

In a multi-core processor system (100), processing related to protocols of the session layer of the OSI reference model is executed by the CPU group for z=0, processing related to protocols of the presentation layer is executed by the CPU group for z=1, and processing related to protocols of the application layer is executed by the CPU group for z=2. The CPU group for z=0 is connected to the CPU group for z=1 via local memory (201), the CPU group for z=1 is connected to the CPU group for z=2 via local memory (202), and the CPU group for z=2 is connected to the main CPU (101) via local memory (203). Packets are passed in hierarchical order of the OSI reference model, and therefore, the CPU group for z=0 is not directly connected to the CPU group for z=2, but is connected only via the CPU group for z=1.
