- 초록
- A multi-core processor connected to main memory or peripheral device and having dual modular redundancy mode in which each processor performs the same task includes a first processor which generates first write-in data by performing the task, and writes the first write-in data to the main memory or peripheral device after fault detection operation on the first write-in data, a second processor which generates second write-in data by performing the task, and prevents writing of the second write-in data to the main memory or peripheral device after the fault detection operation on the second write-in data, and a fault manager which performs the fault detection operation by comparing the first write-in data with the second write-in data in the mode, wherein the first write-in data is written to the main memory using first data cache, which is managed using dirty bit indicating whether to synchronize with the main memory.
