Multiprocessor Systems Using Dedicated External Agents
A multiprocessor system may be created with R10000 processors by providing a dedicated external agent for each processor; such a system is shown in Figure 2-2. The external agent provides a path between the processor System interface and some type of coherent interconnect. In such a system, the processor provides support for three coherency schemes:
- snoopy-based
- snoopy-based with external duplicate tags and control
- directory-based with external directory structure and control
