    摘要: An efficient implementation of DSP functions in a field programmable gate array (FPGA) using one or more computational blocks, each block having of a multiplier, an accumulator, and multiplexers. The structure implements most common DSP equations in a fast and a highly compact manner. A novel method for cascading these blocks with the help of dedicated DSP lines is provided, which leads to a very simple and proficient implementation of n-stage MAC operations.

    摘要: An improved interconnect structure in programmable devices gives a new dimension to the routing architecture, where architecture is divided into various domains. It includes at least one set of input lines, each set having predetermined number of input lines; an equal number of sets of routing lines, each set of routing lines being connected to a corresponding set of input lines using a switch box; thereby forming domain based routing structures, each domain being disjoint with the other domain. Segregating FPGA routing resources into various independent routing domains is done; each domain providing connectivity to route a signal to a set of sinks.
