摘要
The maximum likelihood(ML) solution is used to resolve the full spectrum of nuclear detection,which can be used to decompose the overlapping peaks with the energy difference of 2/3 FWHM.However,the practical application of the algorithm is,due to high and time-consuming,restricted.In this paper,the authors used the OpenCL platform in a heterogeneous system,to achieve the parallel computation of the RL algorithm by the parallel computing capabilities of GPU.The results show that the method can effectively improve operational efficiency.The running time is thirtieth of the original one.
