In the case of driver output resistance, an equivalent device size is determined for the channel-connected components and converted to a small-signal resistance using precomputed coefficients.
Academic text (1999) -
The k-coherence technique combines the propagation idea with a pre-computation stage in which the k nearest neighbors of each patch are cached, and later searches take advantage of these precomputed sets.

Etymology
Precompute is made of pre- meaning 'before' and compute meaning 'to calculate', the same part as computer. So to precompute is to calculate things 'before' you need them, like doing your homework early so a program already has the answers and runs faster.
