Multi-channel Event Capture Circuit in SoC System Realized by Digital Hardware

Zhang Yueling;Zhang Lei;Zhao Zhonghui;Wang Jian;214 Institute of China Weapons Group;  
In the paper,one multi-channel event capture circuit that realized by digital hardware is proposed,and it is applied in the SoC system that embedded multi-DSP.By means of the inner interrupt function and multi-timer that embedded in the large scale SoC system,the multi-channel event capture circuit can achieve capture and storage the time and the state message of the event that come from external input.And then it can read the time and state message about the event after the inner processor cores respond the interrupt.The multi-channel event capture circuit can action as an universal IP model in the SoC system,we simulate it by the interrupt function of the DSP and uniting with the whole system,we test the chip and give the result about the event capture circuit finally.
