In this paper, the interrupt and exception based on YHFT-MP DSP are studied, and the interrupt and exception module of YHFT-MP DSP is analyzed, designed and implemented. Secondly, the verification method of system level block verification program is designed and implemented. The interrupt and exception modules are verified based on simulation and code coverage. Finally, the interrupt module is verified at the operating system level. The main research work includes the following aspects:. 1.
