    摘要: A random-access memory block for a field programmable gate array includes a random-access memory array having address inputs, a data input, a data output and including a plurality of storage locations. At least two programmably invertible enable inputs are provided. Hardwired decoding logic is coupled to the at least two programmably invertible enable inputs to selectively enable the random-access memory array. A gate is coupled to the output of the random-access memory array and is configured to pass the output of the random-access memory array only if the random-access memory is enabled for a read operation, and otherwise generate a preselected logic state.

    摘要: A logic module for an FPGA includes a LUT formed from an N-level tree of 2:1 multiplexers. Each of the N inputs to the LUT is connected to the select inputs of the multiplexers in one level of the tree. Each of the data inputs at the leaves of the tree is driven by a configuration memory cell that produces either a logic 0 or a logic 1. The output of the single multiplexer at the last level of the tree forms a Y output and is coupled to one input of an XOR gate and to the select input of a two-input carry multiplexer. The 0 input of the carry multiplexer is coupled to a G input. A CI input is coupled to the other input of the XOR gate and to the 1 input of the carry multiplexer.

The multiplexer has x address inputs wherein 2x=n as is known in the art. The output of the multiplexer is coupled to Vcc through a pullup transistor. The gate of the pullup transistor is coupled to the output of an address transition detector circuit that has inputs coupled to the address inputs of the multiplexer. A sense amplifier is coupled to the output of the multiplexer.

    摘要: A random access memory circuit adapted for use in a field programmable gate array integrated circuit device is disclosed. The FPGA has a programmable array with logic modules and routing interconnects programmably coupleable to the logic modules and the RAM circuit. The RAM circuit has three ports: a first readable port, a second readable port, and a writeable port. The read ports may be programmably synchronous or asynchronous and have a programmably bypassable output pipeline register. The RAM circuit is especially well adapted for implementing register files. A novel interconnect method is also described.
