A field programmable gate array (FPGA) comprising routing and logic blocks (RLBs) and segmented routing channels is disclosed. Each RLB is configurable to perform both logic functions and routing functions. A plurality of forwardly propagating RLBs (FPRLBs) and a plurality of backwardly propagating RLBs (BPRLBs) intermesh with one another to form a two-dimensional checkerboard array. Each column of the RLB array comprises a plurality of FPRLBs and BPRLBs in alternating sequence. Similarly, each row of the RLB array comprises a plurality of FPRLBs and BPRLBs in alternating sequence. The FPRLBs forwardly propagate signals and the BPRLBs backwardly propagate signals. Each FPRLB may receive a plurality of input signals from a plurality of FPRLBs in the preceding leftward column. Moreover, each FPRLB may output a plurality of output signals to a plurality of FPRLBs in the next rightward column. Similarly, each BPRLB may receive a plurality of input signals from a plurality of BPRLBs in the preceding rightward column and transmit a plurality of output signals to a plurality of BPRLBs in the next leftward column. A plurality of vertical segmented routing channels are disposed between the columns of RLBs, the vertical segmented routing channels accessible to the input and output of adjacent columns of RLBs.
A field programmable gate array comprising: (a) a plurality of forwardly propagating routing and logic blocks (FPRLBs), each of said FPRLBs having means for receiving a plurality of input signals and a plurality of output signals; and (b) a plurality of backwardly propagating routing and logic block
A field programmable gate array comprising: (a) a plurality of forwardly propagating routing and logic blocks (FPRLBs), each of said FPRLBs having means for receiving a plurality of input signals and a plurality of output signals; and (b) a plurality of backwardly propagating routing and logic blocks (BPRLBs), each of said BPRLBs having means for receiving said plurality of input signals and said plurality of output signals, said BPRLBs intermeshing with said FPRLBs to form a two-dimensional checkerboard array, wherein the columns of said checkerboard array comprise a plurality of FPRLBs and BPRLBs arranged in alternating sequence and the rows of said checkerboard array comprise a plurality of FPRLBs and BPRLBs arranged in alternating sequence; wherein each of said FPRLBs not on the periphery of said checkerboard array is communicatively connected to a plurality of BPRLBs in the same column such that said input signals and said output signals may be passed therebetween, wherein each of said BPRLBs not on the periphery of said checkerboard array is communicatively connected to a plurality of FPRLBs in the same column such that said input signals and said output signals may be passed therebetween, wherein each of said FPRLBs not on the periphery of said checkerboard array is communicatively connected to a plurality of FPRLBs in the immediately adjacent leftward column such that said input signals may be received therefrom and a plurality of FPRLBs in the immediately adjacent rightward column such that said output signals may be transmitted thereto, and wherein each of said BPRLBs not on the periphery of said checkerboard array is communicatively connected to a plurality of BPRLBs in the immediately adjacent leftward column such that said output signals may be transmitted thereto and a plurality of BPRLBs in the immediately adjacent rightward column such that said input signals may be received therefrom.
