Abstract
The present invention, generally speaking, relates to taking advantage of existing outputs from logic groupings that neighbor a digital signal processing block in a programmable logic device to expand the functionality of the digital signal processing block. The outputs from the logic groupings are used as dedicated routing interconnects that provide additional inputs into the digital signal processing block (e.g., into function specific blocks) such that the signal processing block receives additional signals. These additional signals can be input into the signal processing block via the dedicated routing interconnect without significant addition of input interconnection resources that are silicon-area expensive.
