- Abstract
- In real-time embedded systems, the responsibility is the most important thing because it is related to human life. Context switching is a part of which can slow down the responsibility. We therefore should minimize the amount of state that needs to be saved during context switching. In this paper, we introduce a new architecture (Register Farm) for context switching which can exchange two contexts in one cycle time. Although it might increase the cost of MCU design and the complexity of circuit, it cannot miss any interrupt during context switching. Consequently, Register Farm architecture can make embedded systems spread out in human life because it can increase reliability and responsibility in real time embedded systems.
