摘要： Interface circuitry that is used to interface data between two different clock regimes that may have somewhat different speeds includes the ability to determine which of the clock regimes is faster. Depending on which clock regime is found to be faster, the baseline (nominal difference between data write and data read addresses of a FIFO memory in the interface circuitry) is shifted (i.e., toward the full or empty condition of the FIFO, as is appropriate for which of the clock regimes has been found to be faster). Adjustments may also be made to the threshold(s) used for such purposes as character insertion/deletion and overflow/underflow indication. This technique may allow use of a smaller FIFO and reduce latency of the interface circuitry.

摘要： The present application discloses apparatus and methods for increasing channel utilization for a high-speed serial interface of an integrated circuit (IC). A new circuit architecture is disclosed which provides circuitry that may be programmed flexibly to support a multitude of different channel bonding schemes. In accordance with one aspect of the invention, the new architecture decouples the granularity of control-signal channel bonding from the granularity of data-aggregation channel bonding. This advantageously allows optimization of configurations for both types of channel bonding. In another aspect of the invention, the logical boundaries of bonded user channels are decoupled from the physical boundaries of the PCS modules. This decoupling advantageously eliminates a rigid constraint of previous architectures.

摘要： A serial data interface for a programmable logic device includes a receiver that deserializes a plurality of channels of received serial data using a recovered clock signal or a phase-aligned received clock signal. Byte boundaries are initially assigned, perhaps arbitrarily, and the deserialized signal is sent to the programmable logic core of the programmable logic device. Programmable logic in the core monitors the byte boundaries on each channel based on the criteria, including any user-defined parameters, programmed into the logic. If a boundary misalignment is detected, a signal is send from the core to bit-slipping circuitry on that channel of the interface to adjust the boundary. The signal could instruct the bit-slipping circuitry to adjust the boundary by the number of bits needed to correct the alignment. Alternatively, the bit-slipping circuitry could operate iteratively, adjusting the boundary by one bit, each cycle, until the signal stops indicating misalignment.

In one embodiment, configurable circuitry is adapted to control an allowed data depth of a plurality of buffers. In another embodiment, configurable circuitry is adapted to control a deskew character transmit insertion frequency. In another embodiment, a programmable state machine is adapted to control read and write pointers in accordance with selectable conditions for achieving an alignment lock condition. In another embodiment, configurable circuitry is adaptable to select between logic and routing resources in the transceiver and logic and routing resources in a core of the IC in which the transceiver is implemented for controlling at least certain deskew operations. In another embodiment, configurable selection circuitry allows deskew processing to occur in a data path either before or after clock compensation processing depending on a communication protocol for which the transceiver is to be configured.

摘要： A megafunction block is provided that includes a serial interface enabling a user to specify settings of a configurable block of a programmable logic device. The megafunction block includes a register array having the capability of translating address information into actual addresses for a memory of the configurable block. Thus, as future configurations/standards are developed that a programmable logic device with the megafunction block will interfaces with, the settings for interfacing with the standards may be added to the register array. Consequently, the pin count will not need to increase as the megafunction block is scalable through the register map. Control logic verifies that the translated address is a valid address and the control logic will generate a selection signal based on whether a read or write operation is to be performed.

摘要： Circuitry for locating the boundaries of bytes in a data stream is provided. The data stream typically has comma or header information that provides an indication of the byte boundaries. When circuitry detects this information, it can align the byte boundaries and thereby provide byte-aligned data to utilization circuitry (e.g., a programmable logic device). In accordance with this invention, circuitry can select different special characters for use in detecting the byte boundaries, where the special characters are different lengths. Circuitry aligns the byte boundaries based on the selected special character when enabled by a control signal. Once aligned, circuitry can provide a signal indicating which special character was used to align the boundaries. Another advantage of the invention is that it eliminates alignment problems associated with system latency. Circuitry automatically locks alignment to a first instance of a detected special character independent of an external control signal.
