The Design and Implementation about One Expanded Interrupt Controller Based on the DSP in SOC Embedded Multi-core

The paper propose one SOC system that embedded multi-DSP, and discusses the interrupt function about the DSP in SOC; Thanks to the peripheral interrupt event in SOC system more than the available interrupt source of the DSP in SOC.Then designs an expanded interrupt controller based on the DSP in SOC, The result displays that the expanded interrupt can process the interrupt request coming form the external service in SOC of multi-DSP. And test the interrupt function about the SOC chip, the result indicate that the multi-DSP in SOC can response the interrupt request coming form peripheral equipment fast and exactly. It is an effect interrupt extend and interrupt control method that can apply in SOC embedded multi-core.
