摘要： Disclosed is a configurable logic circuit that includes at least 6 inputs and at least two outputs. The configurable logic element can carry out only a subset of all 6-input logic functions and, thus, requires a substantially smaller silicon area than a 6-LUT that can perform all 6-input logic functions. Also, the configurable logic circuit can be configured such that a first subset of the inputs drive one of the outputs and a second subset of the inputs drive another output.

摘要： An FPGA architecture has top, middle and low levels. The top level of the architecture is an array of the B16×16 tiles arranged in a rectangular array and enclosed by I/O blocks on the periphery. On each of the four sides of a B16×16 tile, and also associated with each of the I/O blocks is a freeway routing channel. A B16×16 tile in the middle level of hierarchy is a sixteen by sixteen array of B1 blocks. The routing resources in the middle level of hierarchy are expressway routing channels M1, M2, and M3 including groups of interconnect conductors. At the lowest level of the semi-hierarchical FPGA architecture, there are block connect (BC) routing channels, local mesh (LM) routing channels, and direct connect (DC) interconnect conductors. Each BC routing channel is coupled to an expressway tab to provide access for each B1 block to the expressway routing channels M1, M2, and M3, respectively. Each BC routing channel has nine interconnect conductors which are grouped into three groups of three interconnect conductors. Each group of three interconnect conductors is connected to a first side of a Extension Block (EB) 3×3 switch matrix. A second side of each EB 3×3 switch matrix is coupled to the E-tab. Between adjacent B1 blocks , in both the horizontal and vertical directions, the leads on the second side of a first EB 3×3 switch matrix may be coupled to the leads on the second side of second EB3×3 switch matrix by BC criss-cross extension.

摘要： An FPGA architecture has top, middle and low levels. The top level of the architecture is an array of the B16×16 tiles arranged in a rectangular array and enclosed by I/O blocks on the periphery. A B16×16 tile in the middle level of hierarchy is a sixteen by sixteen array of B1 blocks. The B16×16 tile is a nesting of a B2×2 tile that includes a two by two array of four B1 blocks. The routing resources in the middle level of hierarchy are expressway routing channels M1, M2, and M3 including groups of interconnect conductors. The expressway routing channels M1, M2, and M3 are segmented, and between each of the segments in the expressway routing channels M1, M2, and M3 are disposed extensions that can extend the expressway routing channel M1, M2, or M3 an identical distance along the same direction. The expressway routing channels M1, M2, and M3 run both vertically through every column and horizontally through every row of B2×2 tiles. At the intersections of each of the expressway routing channels M1, M2, and M3 in the horizontal direction with the expressway routing channels M1, M2 and M3 in the vertical direction is an expressway turn (E-turn) disposed at the center of each B2×2 tile. An E-turn is a passive device that includes a matrix of reprogrammable switches. The reprogrammable switches are preferably a pass device controlled by an SRAM bit. The interconnect conductors in the expressway routing channels M1, M2 and M3 that are fed into an E-turn may be coupled to many of the other interconnect conductors in the expressway routing channels M1, M2 and M3 that come into the E-turn by the programmable switches. Further, the interconnect conductors in the expressway routing channels M1, M2 and M3 that are fed into an E-turn continue in the same direction through the E-turn, even though the interconnect conductors are coupled to other interconnect conductors by the reprogrammable switches.
