    摘要: Circuits and a method for correcting duty cycle distortions in an integrated circuit (IC) are disclosed. The IC includes a splitter circuit that is coupled to receive a clock signal. The clock signal is split into two different clock signals. One of the clock signals is an inverted version of the other. A delay circuit is coupled to each of the clock signals. Each of the delay circuits generates a delayed version of the corresponding clock signal. A corrector circuit is coupled to receive both the delayed versions of the clock signals. The corrector circuit generates a clock output signal with a corrected duty cycle.

    摘要: Method and circuitry for implementing high speed multiple-data-rate interface architectures for programmable logic devices. The invention partitions I/O pins and their corresponding registers into independent multiple-data rate I/O modules each having at least one pin dedicated to the strobe signal DQS and others to DQ data signals. The modular architecture facilitates pin migration from one generation of PLDs to the next larger generation.

    摘要: Methods and apparatus for providing either high-speed, or lower-speed, flexible inputs and outputs. An input and output structure having a high-speed input, a high-speed output, a low or moderate speed input, and an low or moderate speed output is provided. One of the input and output circuits are selected and the others are deselected. The high-speed input and output circuits are comparatively simple, in one example having only a clear signal for a control line input, and are able to interface to lower speed circuitry inside the core of an integrated circuit. The low or moderate speed input and output circuits are more flexible, for example, having preset, enable, and clear as control line inputs, and are able to support JTAG boundary testing. These parallel high and lower speed circuits are user selectable such that the input output structure is optimized between speed and functionality depending on the requirements of the application.
