The call for efficient computer architectures has introduced a variety of application-specific compute engines to the heterogeneous computing landscape. One particular engine, the analog mesh computer, has been well received due to its ability to efficiently solve partial differential equations by eliminating the iterative stages common to numerical solvers. This article introduces an implementation of adaptive mesh refinement for analog mesh computers, which reduces the energy expended during high-resolution computations of partial differential equations. Results show a larger than 30 expended per computation while reducing precision by less than 5 ideal for green computing systems.
