ABSTRACT:
An improved macrocell is provided for summing product term inputs to complete a sum of products. Some or all of a macrocell's product terms can be allocated to another macrocell. The macrocell OR function remains available to sum product term inputs, even when other product term inputs in the same macrocell are allocated elsewhere. Macrocells can also by daisy-chained bidirectionally, so that the delay associated with allocating product terms between multiple macrocells can be reduced.
