Lookup table sharing for memory-based computing

A computer readable storage medium comprising a computer readable program for memory-based computing, wherein the computer readable program when executed on a computer causes the computer to perform the steps of:

• receiving a request having two numerical inputs and a requested operation;
• and
• reading an operation result value from a multi-operation lookup table using a processor, wherein the multi-operation lookup table 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, wherein the numerical inputs are used as column and row addresses in the lookup table, and wherein the requested operation determines which input corresponds to the column address and which input corresponds to the row address.

A system for memory-based computation, comprising:

• a lookup table comprising result values for an operation;
• and
• a processor configured to receive a plurality of requests, each having two numerical inputs and a requested operation, to combine a first input from each of the plurality of requests into a first combined input, to combine a second input from each of the plurality requests into a second combined input, to read an operation result value from a lookup table to produce a combined result output, and to separate the combined result output into a plurality of individual result outputs corresponding to the plurality of requests.
