Abstract:
Integrated circuits with specialized processing blocks are provided. A specialized processing block may include one real addition stage and one real multiplier stage. The multiplier stage may simultaneously feed its output to the addition stage and directly to an adjacent specialized processing block. The addition stage may also produce sum and difference outputs in parallel. A group of four such specialized processing blocks may be connected in a chain to implement a radix-2 fast Fourier transform (FFT) butterfly. Multiple radix-2 butterflies may be stacked to form yet higher order radix butterflies. If desired, the specialized processing block may also be used to implement a complex multiply operation. Three or four specialized processing blocks may be chained together and along with one or more adders outside the specialized processing blocks, real and imaginary portions of a complex product can be generated.

Claim (Index 1):
An integrated circuit, comprising:\n a plurality of specialized processing blocks connected in a chain, wherein each specialized processing block in the chain includes:\n a first input port that receives a first input signal; \n a second input port that receives a second input signal; \n a third input port that receives a third input signal; \n a first arithmetic circuit that receives the first and second input signals; \n a second arithmetic circuit that selectively receives signals from the first arithmetic circuit and that generates an output signal; and \n a multiplexer having a first input that receives signals directly from the first arithmetic circuit, a second input that receives the third input signal from the third input port, a third input that receives the output signal from the second arithmetic circuit, and an output that is directly connected to an adjacent specialized processing block in the chain.
