Abstract
A specialized processing block such as a DSP block may be enhanced by including direct connections that allow the block output to be directly connected to either the multiplier inputs or the adder inputs of another such block. A programmable integrated circuit device may includes a plurality of such specialized processing blocks. The specialized processing block includes a multiplier having two multiplicand inputs and a product output, an adder having as one adder input the product output of the multiplier, and having a second adder input and an adder output, a direct-connect output of the adder output to a first other one of the specialized processing block, and a direct-connect input from a second other one of the specialized processing block. The direct-connect input connects a direct-connect output of that second other one of the specialized processing block to a first one of the multiplicand inputs.
