Are you trying to compute the sum of many signals for each time point? Or are

To only way to guarantee precision is to use enough bits for intermediate
results. Given your running sum formulation, the worst-case quantization
error for any N is
0.5*Pi + 0.25*Pm*(N+2)(N-1)/N
where Pi is the precision of inputs (the summed signals) and Pm is that of
the partial sum (notic
