Abstract: A processing circuit includes a random access memory (RAM) configured to look up a first next state based on a first address simultaneously with looking up a second next state based on a second address. The first address is formed of a first current state and an input data and the second address is formed of a second current state and the input data. The processing circuit includes a state control circuit that receives the first and second next states, the first current state, and the second current state, and a first-in-first-out (FIFO) memory that stores selected ones of the first and second next states, the first current state, and the second current state. The processing circuit includes a multiplexer configured to selectively pass two states from the FIFO memory or two states from the state control circuit as a third current state and a fourth current state.

Abstract: A high performance field programmable gate array is described with one or more signal processing engines coupled to a programmable logic fabric. Each signal processing engine includes a signal processing unit for performing specifying tasks and a bus-based configurable connection box for routing a bus-based input to a bus-based output. The signal processing unit has a floating point unit (FPU)/multiply accumulate (MAC) for computation and register files for storing information. The programmable logic fabric is coupled to the one or more signal processing engines for routing of information between the signal processing engines.

Abstract: Logic design apparatus and method provides serial multiplexer chains in a programmable logic fabric, each element in the chain either selects output of block, or passes output from earlier element of the chain. Select line is a decoder structure or output from configurable function generator that is configured at power-on to create correct selection. Using such structure, larger multiplexer, including priority multiplexers, tristate buses or larger look-up tables (LUTs) can be created. These novel structures can implement priority, non-priority or tristate multiplexers.

Abstract: A function generator is described that can be configured as a combinational logic, sequential logic, or routing cell. The function generator couples to a plurality of selector blocks that select a wire from a plurality of inputs. The selected wires are inputs to a function generator. The function generator, when configured as a combinational logic cell, can generate any function of its inputs. The function generator, when configured as a sequential logic cell, behaves as a register, where any of the inputs can be directed to input data, clear, clock enable, or reset signals. The register is configurable to a falling or rising edge flip-flop or a positive or negative level sensitive latch. As a routing element, logic cells selects one of its inputs. The output of the programmable cell can fan out to one or more inputs of another integrated cell.
