Abstract
Methods and systems for memory-based computing include combining multiple operations into a single lookup table and combining multiple memory-based operation requests into a single read request. Operation result values are read from a multi-operation lookup table that includes result values for a first operation above a diagonal of the lookup table and includes result values for a second operation below the diagonal. Numerical inputs are used as column and row addresses in the lookup table and the requested operation determines which input corresponds to the column address and which input corresponds to the row address. Multiple operations are combined into a single request by combining respective members from each operation into respective inputs an reading an operation result value from a lookup table to produce a combined result output. The combined result output is separated into a plurality of individual result outputs corresponding to the plurality of requests.
