    • One or more columns of multi-function tiles are positioned between CLB tiles of the FPGA array. Each multi-function tile includes multiple function elements that share routing resources. In one embodiment, a multi-function tile includes a configurable, dual-ported RAM and a multiplier that share routing resources of the multi-function tile. The RAM includes first and second input ports coupled to first and second input data buses, respectively, and includes first and second output ports coupled to first and second output data buses, respectively. The multiplier includes first and second operand ports coupled to receive operands from the first and second input data buses, and in response thereto provides a product. In one embodiment, the most significant bits (MSBs) of the product are selectively provided to the first output data bus using bus multiplexer logic, and the least significant bits (LSBs) of the product are selectively provided to the second output data bus using bus multiplexer logic.

    • The invention comprises an FPGA having a plurality of input reference voltages and/or output voltage supplies. In one embodiment, two or more differential amplifiers in the same configurable input buffer use different input reference voltages. According to a second aspect of the invention, the I/O pad line is configurably connected to the input reference voltage line, so that any configurable Input/Output Block (IOB) can be used to supply the input reference voltage. According to a third aspect of the invention, the reference input of an I/O is configurably connected to any of two or more input reference voltage lines. According to another aspect of the invention, a single input reference voltage and/or a single output voltage supply is applied to each IOB, with the IOBs grouped into sets. Each set of IOBs has a separate input reference voltage and/or a separate output voltage supply.

    • In a multiplier architecture, all stages of a multiplication function are implemented using a uniform array of logic blocks. An exemplary multiplier circuit includes a two-dimensional array of substantially similar logic blocks. Each logic block includes a multiply block and a logic circuit driven by the multiply block. The logic circuit is coupled to implement an add function. A first portion of the array is coupled to receive the first and second multiplicand inputs, to provide a partial product bus, and to provide lower bits of the product output. A second portion is coupled to receive the partial product bus from the first portion of the array, and to provide from the partial product bus upper bits of the product output. The multiply blocks may be non-uniform arrays, e.g., logical AND gates and full adders in all but one column, with only logical AND gates in the remaining column.
    • 在乘法器架构中,乘法函数的所有阶段都使用统一的逻辑块阵列来实现。 示例性乘法器电路包括基本相似的逻辑块的二维阵列。 每个逻辑块包括乘法块和乘法块驱动的逻辑电路。 逻辑电路被耦合以实现加法功能。 阵列的第一部分被耦合以接收第一和第二被乘数输入,以提供部分乘积总线,并提供产品输出的较低位。 第二部分被耦合以从阵列的第一部分接收部分乘积总线,并且从部分乘积总线提供产品输出的较高位。 乘法块可以是除了一列之外的不均匀的阵列,例如逻辑与门和全加法器,在剩余的列中只有逻辑与门。
