definitions 96 A DG can be transformed to a space-time representation by interpreting one of the spatial dimensions as temporal dimension(时间维度). For a 2-D DG,the general transformation is described by i'=t=0,j'=p I,and t'=sTI,i.e. j':processor axis t':scheduling time instance 2021年2月 92021年2月 9 definitions  A DG can be transformed to a space-time representation by interpreting one of the spatial dimensions as temporal dimension(时间维度).  For a 2-D DG, the general transformation is described by i’=t=0, j’=pT I, and t’=sT I, i.e. j’ : processor axis t’ : scheduling time instance
