摘要： An integrated circuit in a multi-chip package is provided. The integrated circuit may include adjustable interface circuitry configured to interface with other off-chip components. In particular, the adjustable interface circuitry may include a microbump input-output buffer operable to drive signals off of the integrated circuit and operable to receive signals from other integrated circuits in the multi-chip package via a microbump. The microbump input-output buffer may include output buffers and input buffers. The output buffers may have programmable drive strengths and may each be selectively switched in and out of use depending on the desired application. Each output buffer may include a level shifter, a buffer circuit, and multiple inverter-like circuits each of which can be turned on or off to adjust the drive strength of that output buffer.

摘要： A high-performance programmable logic architecture has embedded memory (608). arranged at the peripheries or edges of the integrated circuit. This enhances the performance of the programmable logic integrated circuit by shortening the lengths of the programmable interconnect (748). In a specific embodiment, the memory blocks (703) are organized in rows along the top and bottom edges of the integrated circuit. The logic elements (805) can be directly programmable routed and connected to driver blocks (809) of the logic block in adjacent rows and columns. This permits fast interconnection of signals without using the global programmable interconnect resources (815, 825). Using similar direct programmable interconnections (828, 830, 835), the logic blocks can directly programmable connect to the memory blocks without using the global programmable interconnect resources. The present invention also provides technique of flexibly combining or stitching multiple memories together to form memories of a desired size.

摘要： A programmable logic device includes, in addition to the usual regions of programmable logic and the programmable interconnect, at least one region of memory which has multiple independently usable write and/or read ports (e.g., two write ports and two read ports). Every memory cell in the memory region is accessible from any of these ports. This enables the memory region to be used to provide either one relatively large memory or two somewhat smaller memories, each occupying a fraction of the full memory. In the latter case, the two memories provided can have any of many different sizes relative to one another. Many different modes or combinations of modes of operating the memory region or parts of the memory region are possible.

摘要： A programmable logic integrated circuit device has a plurality of regions of programmable logic disposed on the device in a plurality of intersecting rows and columns of such regions. Interconnection resources (e.g., interconnection conductors, signal buffers/drivers, programmable connectors, etc.) are provided on the device for making programmable interconnections to, from, and/or between the regions. At least some of these interconnection resources are provided in two forms that are architecturally similar (e.g., with similar and substantially parallel routing) but that have significantly different signal propagation speed characteristics. For example, a major or larger portion of such dual-form interconnection resources may have what may be termed normal signal speed, while a smaller minor portion may have significantly faster signal speed. Secondary (e.g., clock and clear) signal distribution may also be enhanced, and so may be input/output circuitry and cascade connections between adjacent or nearby logic modules on the device.

摘要： Techniques for providing high-performance interconnect for integrated circuits will improve overall integrated circuit performance. These techniques include arranging, laying out, and fabricating the signal conductors (e.g., 405, 720) so the parasitic coupling capacitances (e.g., 425) are minimized and parasitic resistance is reduced. The techniques will minimize effects of crosstalk noise between the conductors, and thus improve overall integrated circuit performance.

摘要： A first-in-first-out memory may have first and second memory banks. A write controller may write data into the first and second memory banks. In performing write operations, the write controller may determine whether to write the data into the first bank or the second bank by evaluating a first bank empty flag and a second bank empty flag. When transitioning between writing in the first bank and the second bank, the write controller may latch a write address value indicative of the last location at which valid data was written in a given bank. A read controller may read data from the first and second memory bank. The read controller may determine when to transition between reading in the first bank and reading in the second bank by comparing a current read address to the latched write address value.

摘要： An integrated circuit system may include a first integrated circuit (IC), a second IC, and interface circuitry. The first IC is operable to output a parallel data stream at a first data rate. The second IC is operable to output a serialized data stream at a second date rate. The second data rate may be different than the first data rate. The interface circuitry may be coupled between the first integrated circuit and the second integrated circuit. The interface circuitry may be operable to convert the parallel data stream received from the first IC into a serialized data stream with the second data rate.

摘要： A programmable logic device has many regions of programmable logic, together with relatively general-purpose, programmable, interconnection resources that can be used to make interconnections between virtually any of the logic regions. In addition, various types of more local interconnection resources are associated with each logic region for facilitating the making of interconnections between adjacent or nearby logic regions without the need to use the general-purpose interconnection resources for those interconnections. The local interconnection resources support flexible clustering of logic regions via relatively direct and therefore high-speed interconnections, preferably in both horizontal and vertical directions in the typically two-dimensional array of logic regions. The logic region clustering options provided by the local interconnection resources are preferably boundary-less or substantially boundary-less within the array of logic regions.
