A programmable element for data processing comprises a crosspoint switch ( 318 ), a mathematical operation module ( 320 ), and a plurality of data hold modules ( 604,606 ). Each of the data hold modules ( 604,606 ) receives data from the crosspoint switch ( 318 ) and communicates the data to an input of the mathematical operation module ( 320 ) such that data arrives at the inputs of the mathematical operation module ( 320 ) substantially simultaneously. A first data hold module ( 604 ) communicates a first data valid signal to a second data hold module ( 606 ) upon receipt of first valid data, and the second data hold module communicates a second data valid signal to the first data hold module upon receipt of second valid data. The first data hold module ( 604 ) communicates the first valid data to a first input upon receipt of the first valid data and the second data valid signal, and the second data hold module ( 606 ) communicates the second valid data to a second input upon receipt of the second valid data and the first data valid signal.
